Every module has a certain amount of health (visible in the repair shop or when you compare multiple mods from the variants tab on the info screen), found in the attributes tab of the info window for the module. When the amount of heat damage sustained is greater than the module health, the module will 'burn out' and be forced Offline until it is repaired in a station's repair shop. Heat damage and module health are non-integer numbers, and so even if a module has sustained 39.99/40HP in heat damage, it will still operate. Burned out modules cannot be repaired and reactivated in space, and must be taken to a starbase or citadel to be repaired. Module heat damage can be repaired either in a starbase Repair Shop, or by being Tethered to an Upwell Structure.

=== Rack Heat ===
  
−
As an overheated module cycles, it causes heat to build up in its rack (high/mid/low). Every time an overheated module's cycle ends, it has a chance to deal heat damage to one or more modules in the rack (including itself more than not). Every module has a fixed amount of heat damage it can deal on a cycle, which can be found in the attributes tab of the module's info window. The tachyometer-looking heat displays around the capacitor in the central HUD display both the heat built up in the rack (from 0-100%), and a kind of damage multiplier, from 1-4, that increases the number of different modules in that rack which can sustain heat damage from a single cycle. Heat buildup in racks is linear, and is based on the number of modules overheated at one time, the type of the modules (not visible in-game, but visible in out-of-game data sheets as 'heatAbsorbtionRateModifier'), and the size of the ship (larger hulls build up heat slower, also not visible in game but found on data sheets as 'heatGenerationModifier'). However, heat dissipation is not linear, it's based on how hot the rack currently is. This means that it is most dangerous to leave large numbers of modules overheated continuously, and safer to use overheating on individual modules in short bursts of a few cycles at a time, waiting for the rack heat to dissipate in between.
+
Module heat damage is handled on a rack-by-rack basis, with the High Power, Mid Power, and Low Power modules each being handled independent of each other. As overheated modules cycle, they build up heat within their racks. The three segmented bars in the center HUD, between the capacitor and hitpoint bars, are the heat indicators for the racks (in order left-to-right of low|mid|high). Rack heat generation occurs continuously while modules are overheating, at a rate based on the number of modules being overheated, the type of those modules, and the size of the ship overheating them. Larger ships generate rack heat more slowly than smaller ships.

Two modules overheated, and next to each other in the same rack will damage each other as well as themselves, causing them to burn out that much faster. Care has to be taken whilst fitting a ship to try and fit modules that are likely to be overheated away from each other. Note that whether or not modules are 'next to each other' is determined on the fitting screen, and not the location of the buttons on your screen in space. Moving the buttons around has no effect on heat transfer. Minchurra has shown the effects of spacing modules with experimental science: [https://www.youtube.com/watch?v=nvpi95zHl90&feature=youtu.be How does module spacing affect heat damage?].

Some people fit offlined modules in between modules they plan on overheating to act as a 'heat sink' and limit the transfer of heat. Of course, this means a slot isn't being fully used, and could be a waste, so a balance has to be struck (however, this can be a good option for utility slots, eg. the 8th high slot on a ship with 7 missile or turret hardpoints). What happens is, if the RNG for the splash damage hits the offlined module or the empty slot, no damage is done and you can effectively overheat longer. Note that empty and offline slots are effectively equivalent for overheating purposes, so there's no need to place modules you won't ever online. However, an online module instead of an offline module will increase the rate at which modules burn out. Minchurra has done a nice bit of science about this: [https://www.youtube.com/watch?v=7V3ueIUBr3U Turning down the heat (Overheating part 2)].

The values from these tables cannot be found in game. They must be found on outside sources.

==== Rack Heat Dissipation ====
 +
 
 +
Rack heat dissipates continuously, at a rate proportional to how hot the rack is, via a very simple formula: Heat Dissipation per second = (Current Rack Heat %) * 1%. (For Example: at 60% rack heat, the rack will lose heat at 0.6%/second). This heat dissipation occurs regardless of how many modules are currently being overheated. As a result, rack heat generation may appear to be nonlinear, as rack heat will rise more slowly the closer the rack is to 100% heat (from the increased dissipation). Also as a result, if only one module on a ship is being overheated, a large enough ship may never reach 100% heat on that rack. Rack Heat is '''not''' immediately removed when a ship is docked ''or Repaired'', it continues to dissipate at the normal rate; as a result, if a ship is docked to repair heat damage and immediately undocked, its racks may still have heat left in them even if its modules have been repaired.
 +
 
 +
=== Module Heat Damage ===
 +
 
 +
Every time an overheated module's cycle ends, that module has a chance to deal Heat Damage (not to be confused with the Thermal Damage dealt by ship weapons) to itself and other modules on the same rack. The amount of damage a module will deal to other modules on an overheat cycle is visible in game in a module's Show Info window, under the name <code>Heat damage</code>. These values are generally higher for smaller-ship modules, lower for larger-ship modules, and somewhat proportionate to the modules' cycle times. (Faster-cycling modules generally have lower heat damage.) This Heat Damage value is the value which can be reduced by the skills listed at the top of this page. This is also the value which is increased by the negative system effect of [[Wormhole_space#Red_Giant|Red Giant Wormhole systems]]. Modules will not always deal heat damage to themselves or others on every cycle ending, but when they do deal heat damage they will always deal exactly their listed amount of damage. Modules which have sustained heat damage will start to show red outlines around their icons in the hotbar (more red indicating more heat damage). The red outline will flash when a module sustains further heat damage from additional overheat cycles.
 +
 
 +
Module heat damage can be repaired in three ways:
 +
 
 +
* Docking in a Starbase with a Repair Shop, or an Upwell Structure, and either bringing up the Repair Shop window from the starbase menu, or right-clicking on the damaged ship (or modules if they are unfitted) and selecting <code>Get Repair Quote</code>. Repairs in an NPC-owned station cost ISK.
 +
* Tethering to an Upwell Structure. While Tethered to an Upwell Structure, the Tether effect will repair module heat damage as well as the more visible shield/armor/hull/capacitor repairs it grants. However, this repair can be inconsistent at times, and either may not repair all damaged modules or may not repair them fully.
 +
* Consuming Nanite Repair Paste. Right-clicking the icon for a damaged, not-actively-cycling module in the hotbar will bring up a menu, containing the option <code>Repair</code> and a number in parentheses. That number is the amount of Nanite Repair Paste that will be consumed to perform the repairs. Selecting this option will begin to slowly repair the module (but will not immediately remove the Paste from cargohold. Paste used in repairs is removed from cargo when the repair completes.) While a module is being repaired, the module cannot be activated, and no other modules on the ship can be overheated. Repairs can be cancelled from the same right-click menu. Cancelling a repair before it is complete will stop the repair at its current point, and remove repair paste from cargo based on how far the repair got. It is not possible to begin repairing a module if there is not enough paste in cargo to fully finish repairing it. Note however that it ''is'' possible to repair a module while it is being reloaded. This is a commonly recommended tactic for use on Ancillary repair modules and Rapid missile launchers.
 +
 
 +
 
 +
=== Module Burnout ===
 +
 
 +
Every module has a certain amount of hitpoints (visible in its Show Info panel as <code>Structure Hitpoints</code>). In almost all cases, this value is 40HP, however for certain capital ship modules like Doomsday Weapons the value is in stead 99999HP or 999999HP (indicating that these modules effectively cannot be burned out by other modules' heat damage). If a module sustains heat damage exceeding its structure hitpoints, the module will 'burn out', being forcibly set offline. A burned out module cannot be repaired with Nanite Repair Paste, and cannot be set online again until it has been repaired. Ideally, burned out modules should be repaired via a starbase or structure repair shop, however if a burned out module is partially repaired by being Tethered to an Upwell Structure, it can be brought online again while still in space. Burned out modules do not automatically re-online after being repaired; they must be manually reactivated.
 +
 
 +
=== Module Heat Damage Odds ===
 +
 
 +
As was mentioned, modules being overheated can, but may not always, deal heat damage to themselves and other modules. The odds of this happening is based on several factors:
 +
 
 +
* The '''Rack Heat''' of the rack being overheated. As Rack Heat rises, the odds of heat damage instances occurring increases, and the odds of larger numbers of modules being damaged by one proc increases. In the past, this was erroneously believed to be a simple 1-4 multiplier on the number of modules that could be damaged at once, but in reality it acts as a percentage chance for a given module to receive heat damage, after the results of the other factors. (It is theoretically possible for every single module in a rack to be damaged by a single overheat cycle, however in practice this is highly unlikely.)
 +
* The '''placement of modules''' in the rack. Modules that are being overheated have the highest chance to deal heat damage instances to themselves and to immediately adjacent modules. Every additional module slot of distance away from an overheating module reduces the chances of that other module being damaged, to the point that modules on opposite ends of a rack have the lowest chances to damage each other. If a module is on the far end of a rack, or has only empty slots to one side of it, it may attempt to deal heat damage to the nonexistant modules off the end of the rack, which will result in the module itself erroneously flashing to indicate heat damage being dealt, and no heat damage actually being dealt in that direction. The result of this is that in a rack where only a small number of modules will be overheated, the best slots to place those modules is either on one far end (for one overheating module), opposite far ends (for two), or as evenly spaced across the rack as possible (for more); and the worst slots to place overheating modules in is either the center of the rack (causing it to damage all other modules in the rack) or adjacent to another to-be-overheated module (as they will damage and burn each other out). Note that these module placements apply to the fitting screen, not the hotbar; the placement of module buttons on the hotbar does not matter.
 +
* The number of '''Online''', versus '''Offline''' or '''Empty''', slots in the rack. Based on [https://www.youtube.com/watch?v=7V3ueIUBr3U research performed in 2017] by Minchurra, the odds for a module to damage not just other modules but also ''itself'' is related to whether or not it is adjacent to other online modules, versus being adjacent to offline modules or empty slots. As per his research, a module which has multiple adjacent Online modules is significantly more likely to damage itself while being overheated, than a module with multiple adjacent Offline modules (or empty slots).
 +
* The '''ship''', and the number of '''slots''' in the rack. Every ship hull has three hidden attributes (named <code>heatAttenuationHi</code>, <code>heatAttenuationLow</code>, and <code>heatAttenuationMid</code>). In general, the values of these attributes correspond to the number of slots in the rack, with the numbers being higher for racks with more slots. Higher values of these attributes represent greater chances for heat damage to ''not'' be dealt in a cycle, either to the source module or an adjacent module. This reduction is usually cancelled out by the rack having more modules in it for heat to bounce between, but it also means that if a ship has only one overheated module in a long but entirely empty rack, that one module will have an extremely long lifespan.
 +
 
 +
=== Heat Sinking ===
 +
 
 +
Not to be confused with the module which increases Energy Turret damage, Heat Sinking is the commonly discussed practice of including either empty slots or unused modules to absorb heat damage in a rack and increase the lifespan of other modules in the rack. As has been demonstrated by the above section, this can be an effective and valuable strategy, including one or more empty slots or offline modules in a rack of otherwise hot modules. This is most commonly done in a ship's high slots, as mid and low slots are generally seen as far too valuable to sacrifice, but as has also been demonstrated, there are both correct and incorrect ways to heat sink a rack. The correct way to heat sink a rack of modules (usually weapons) is to spread the weapons as far apart and as evenly as possible, and then evenly intersperse a set of either Offline modules or Empty slots in between the guns. (Don't give up a Turret or Launcher Hardpoint just to get a better heat sink though. You still want to have the full set.) The incorrect way to heat sink a rack is either to leave all of the modules lined up next to each other (as the fitting system will usually do by default), or to evenly intersperse additional Online modules across the rack (as Online modules will echo heat damage).

a class on:

Overheating (sometimes also called overloading) a module allows you to get more output from it for a short time. As the name suggests, overheating isn't something you can do indefinitely. Eventually you will burn your module out, making it inoperable.

However, if used with care or in an emergency, the benefit gained from an overheated module could be the difference between losing your ship and killing your enemy. Good pilots know when the risk is worth the possible reward.

Overheating -- and knowing how and when to do it -- is a very important skill in small fleet and solo PvP.

Skills

Overheating in action. The repper in the lowslots is not active but is primed to overheat when it is reactivated. The buttons for overheating the full mid and low racks have lit up because the pilot has overheated all the modules that can be overheated in these racks. The Damage Control in the second low slot is an example of a module which cannot be overheated. The red indicators between the capacitor and hitpoint bars are the heat accumulated in the low/mid/high racks, and the red shown on the module icons is the overheat damage sustained by the module.

The skill required to be able to overheat your modules is called Thermodynamics (3x, 4.5M ISK). This skill reduced the heat damage from overheating by 5% per skill level. This is a starting skill for characters made after the September 2015 Vanguard update, but before the September 2019 update. (Older and newer characters will need to train the requisites and this skill on their own.)

Support Skills

Additionally, Tactical Destroyers and Strategic Cruisers have skills which improve their ability to overheat modules.

  • (Racial) Tactical Destroyer - Provides 5% reduction to heat damage from overheating per level.
  • (Racial) Strategic Cruiser - Provides 5% reduction to heat damage from overheating, and 10% increase in damaged module repair amount per second, per level.
  • (Racial) Core Systems - Provides 5% reduction to heat damage from overheating per level, when the associated electronic warfare Subsystem is fitted.

Controlling Overheating

You can begin overheating a specific module by clicking the green light at the top of the module button. You can turn it off the same way -- note, though, that it won't turn on or off until the next cycle begins. Alternatively you can right click the module and choose to overheat it. You can also use a keyboard shortcut: by default you can overheat by holding down shift and pressing the key(s) required to activate a module normally.

In some circumstances, you may need to overheat many modules as fast as possible. You can choose to overheat an entire rack (all the highslots, all the mid slots, or all the low slots) via the small buttons to the left of each rack.

The effects of overheating vary depending on the module. Most weapons will generate more damage (in the region of 15%). Tackling modules like webifiers get more range (about 20%). Propulsion devices like Afterburners boost your speed even more (roughly 50% more). With such benefits, it is easy to see that overheating is very powerful in the right circumstances.

Not all modules can be overheated - cloaking devices and damage controls can't, for example.

Red Giants

Wormhole space systems with the Red Giant effect have a significant impact on overheating modules. On the one hand, the system effect increases the magnitude of module overheat effects (listed below), however on the other hand, the system effect also increases the damage inflicted by modules when they overheat, reducing margin of error and causing modules to burn out faster. Overheating in Red Giant systems must be done much more selectively than in other regions of space.

Notes

  • Shield Boosters and Armor Repairers have multiple effects.
  • Weapon DPS bonuses aren't uniform: missile launchers and long-ranged turrets (artillery, beam lasers, and railguns) fire faster, while short-ranged turrets (autocannons, pulse lasers, blasters, and disintegrators) get more raw damage-per-shot. Both ultimately result in more DPS, but it's worth noting that overheating won't give you a bigger alpha strike when you're using missiles or long-ranged turrets.

Heat

Modules that are overheated generate heat. This heat builds up in the ship (separated by module racks), and causes damage other modules in the same rack. Heat damage is what limits the use of overheating and has to be balanced between the need for the extra boost, and the risk of losing the module.

Rack Heat

Module heat damage is handled on a rack-by-rack basis, with the High Power, Mid Power, and Low Power modules each being handled independent of each other. As overheated modules cycle, they build up heat within their racks. The three segmented bars in the center HUD, between the capacitor and hitpoint bars, are the heat indicators for the racks (in order left-to-right of low|mid|high). Rack heat generation occurs continuously while modules are overheating, at a rate based on the number of modules being overheated, the type of those modules, and the size of the ship overheating them. Larger ships generate rack heat more slowly than smaller ships.

Module Type Rack Heat Generation/second
Afterburner, Microwarpdrive 4%
Armor Hardener, Shield Hardener 2%
All other modules 1%


Hull Size Rack Heat Generation Rate
Frigate, Interdictor, Command Destroyer[1] 100%
Destroyer 85%
Cruiser, Industrial, Mining Barge 75%
Battlecruiser 65%
Battleship 50%
Carrier, Force Auxiliary 40%
Dreadnought, Supercarrier, Orca, Rorqual 35%
Titan 25%
  1. ^ Most T2 ships have the same heat generation as their T1 variants. T2 Destroyers are the exception.

The values from these tables cannot be found in game. They must be found on outside sources. Module heat generation rates can be found on modules, under the attribute heatAbsorbtionRateModifier, and hull heat generation modifiers can be found on ship hulls, under the attribute heatGenerationModifier.

Rack Heat Dissipation

Rack heat dissipates continuously, at a rate proportional to how hot the rack is, via a very simple formula: Heat Dissipation per second = (Current Rack Heat %) * 1%. (For Example: at 60% rack heat, the rack will lose heat at 0.6%/second). This heat dissipation occurs regardless of how many modules are currently being overheated. As a result, rack heat generation may appear to be nonlinear, as rack heat will rise more slowly the closer the rack is to 100% heat (from the increased dissipation). Also as a result, if only one module on a ship is being overheated, a large enough ship may never reach 100% heat on that rack. Rack Heat is not immediately removed when a ship is docked or Repaired, it continues to dissipate at the normal rate; as a result, if a ship is docked to repair heat damage and immediately undocked, its racks may still have heat left in them even if its modules have been repaired.

Module Heat Damage

Every time an overheated module's cycle ends, that module has a chance to deal Heat Damage (not to be confused with the Thermal Damage dealt by ship weapons) to itself and other modules on the same rack. The amount of damage a module will deal to other modules on an overheat cycle is visible in game in a module's Show Info window, under the name Heat damage. These values are generally higher for smaller-ship modules, lower for larger-ship modules, and somewhat proportionate to the modules' cycle times. (Faster-cycling modules generally have lower heat damage.) This Heat Damage value is the value which can be reduced by the skills listed at the top of this page. This is also the value which is increased by the negative system effect of Red Giant Wormhole systems. Modules will not always deal heat damage to themselves or others on every cycle ending, but when they do deal heat damage they will always deal exactly their listed amount of damage. Modules which have sustained heat damage will start to show red outlines around their icons in the hotbar (more red indicating more heat damage). The red outline will flash when a module sustains further heat damage from additional overheat cycles.

Module heat damage can be repaired in three ways:

  • Docking in a Starbase with a Repair Shop, or an Upwell Structure, and either bringing up the Repair Shop window from the starbase menu, or right-clicking on the damaged ship (or modules if they are unfitted) and selecting Get Repair Quote. Repairs in an NPC-owned station cost ISK.
  • Tethering to an Upwell Structure. While Tethered to an Upwell Structure, the Tether effect will repair module heat damage as well as the more visible shield/armor/hull/capacitor repairs it grants. However, this repair can be inconsistent at times, and either may not repair all damaged modules or may not repair them fully.
  • Consuming Nanite Repair Paste. Right-clicking the icon for a damaged, not-actively-cycling module in the hotbar will bring up a menu, containing the option Repair and a number in parentheses. That number is the amount of Nanite Repair Paste that will be consumed to perform the repairs. Selecting this option will begin to slowly repair the module (but will not immediately remove the Paste from cargohold. Paste used in repairs is removed from cargo when the repair completes.) While a module is being repaired, the module cannot be activated, and no other modules on the ship can be overheated. Repairs can be cancelled from the same right-click menu. Cancelling a repair before it is complete will stop the repair at its current point, and remove repair paste from cargo based on how far the repair got. It is not possible to begin repairing a module if there is not enough paste in cargo to fully finish repairing it. Note however that it is possible to repair a module while it is being reloaded. This is a commonly recommended tactic for use on Ancillary repair modules and Rapid missile launchers.


Module Burnout

Every module has a certain amount of hitpoints (visible in its Show Info panel as Structure Hitpoints). In almost all cases, this value is 40HP, however for certain capital ship modules like Doomsday Weapons the value is in stead 99999HP or 999999HP (indicating that these modules effectively cannot be burned out by other modules' heat damage). If a module sustains heat damage exceeding its structure hitpoints, the module will 'burn out', being forcibly set offline. A burned out module cannot be repaired with Nanite Repair Paste, and cannot be set online again until it has been repaired. Ideally, burned out modules should be repaired via a starbase or structure repair shop, however if a burned out module is partially repaired by being Tethered to an Upwell Structure, it can be brought online again while still in space. Burned out modules do not automatically re-online after being repaired; they must be manually reactivated.

Module Heat Damage Odds

As was mentioned, modules being overheated can, but may not always, deal heat damage to themselves and other modules. The odds of this happening is based on several factors:

  • The Rack Heat of the rack being overheated. As Rack Heat rises, the odds of heat damage instances occurring increases, and the odds of larger numbers of modules being damaged by one proc increases. In the past, this was erroneously believed to be a simple 1-4 multiplier on the number of modules that could be damaged at once, but in reality it acts as a percentage chance for a given module to receive heat damage, after the results of the other factors. (It is theoretically possible for every single module in a rack to be damaged by a single overheat cycle, however in practice this is highly unlikely.)
  • The placement of modules in the rack. Modules that are being overheated have the highest chance to deal heat damage instances to themselves and to immediately adjacent modules. Every additional module slot of distance away from an overheating module reduces the chances of that other module being damaged, to the point that modules on opposite ends of a rack have the lowest chances to damage each other. If a module is on the far end of a rack, or has only empty slots to one side of it, it may attempt to deal heat damage to the nonexistant modules off the end of the rack, which will result in the module itself erroneously flashing to indicate heat damage being dealt, and no heat damage actually being dealt in that direction. The result of this is that in a rack where only a small number of modules will be overheated, the best slots to place those modules is either on one far end (for one overheating module), opposite far ends (for two), or as evenly spaced across the rack as possible (for more); and the worst slots to place overheating modules in is either the center of the rack (causing it to damage all other modules in the rack) or adjacent to another to-be-overheated module (as they will damage and burn each other out). Note that these module placements apply to the fitting screen, not the hotbar; the placement of module buttons on the hotbar does not matter.
  • The number of Online, versus Offline or Empty, slots in the rack. Based on research performed in 2017 by Minchurra, the odds for a module to damage not just other modules but also itself is related to whether or not it is adjacent to other online modules, versus being adjacent to offline modules or empty slots. As per his research, a module which has multiple adjacent Online modules is significantly more likely to damage itself while being overheated, than a module with multiple adjacent Offline modules (or empty slots).
  • The ship, and the number of slots in the rack. Every ship hull has three hidden attributes (named heatAttenuationHi, heatAttenuationLow, and heatAttenuationMid). In general, the values of these attributes correspond to the number of slots in the rack, with the numbers being higher for racks with more slots. Higher values of these attributes represent greater chances for heat damage to not be dealt in a cycle, either to the source module or an adjacent module. This reduction is usually cancelled out by the rack having more modules in it for heat to bounce between, but it also means that if a ship has only one overheated module in a long but entirely empty rack, that one module will have an extremely long lifespan.

Heat Sinking

Not to be confused with the module which increases Energy Turret damage, Heat Sinking is the commonly discussed practice of including either empty slots or unused modules to absorb heat damage in a rack and increase the lifespan of other modules in the rack. As has been demonstrated by the above section, this can be an effective and valuable strategy, including one or more empty slots or offline modules in a rack of otherwise hot modules. This is most commonly done in a ship's high slots, as mid and low slots are generally seen as far too valuable to sacrifice, but as has also been demonstrated, there are both correct and incorrect ways to heat sink a rack. The correct way to heat sink a rack of modules (usually weapons) is to spread the weapons as far apart and as evenly as possible, and then evenly intersperse a set of either Offline modules or Empty slots in between the guns. (Don't give up a Turret or Launcher Hardpoint just to get a better heat sink though. You still want to have the full set.) The incorrect way to heat sink a rack is either to leave all of the modules lined up next to each other (as the fitting system will usually do by default), or to evenly intersperse additional Online modules across the rack (as Online modules will echo heat damage).

Repairing Heat Damage

If a module has been damaged by heat, but not destroyed, then in-space repairs can be made using Nanite repair paste. This isn't excessively expensive, but the costs can add up if you use it a lot. Repair is done by right clicking the damaged module and selecting repair. As a rough rule of thumb, 1 minute, and 1 unit of paste repairs 10 points of heat damage. Likewise, frigates should carry 100 units in their cargo hold, cruisers and battle-cruisers 200 units, and larger vessels 300 units. Several skills can be trained to speed up repair time, and reduce the amount of paste required. If a module is destroyed (burned out) then it can't be repaired with nanite paste and will have to be repaired in a station with a repair shop.

You can't use a module while it's being repaired, and you can't overheat anything while any module on your ship is being repaired.
