Overheating

Overloading (sometimes also called overheating) a module allows you to get more output from it for a short time. As the name suggests, overloading 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 overloaded module could be the difference between losing your ship and killing your enemy. Good pilots know when the risk is worth the possible reward.

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

Skills

Overloading in action. The repper in the lowslots is not active but is primed to overload when it is reactivated. The buttons for overloading the full mid and low racks have lit up because the pilot has overloaded all the modules that can be overloaded in these racks. The Damage Control in the second low slot is an example of a module which cannot be overloaded.

The skill requirements for Overloading were lowered significantly with the Dominion expansion (in December 2009) bringing it within the reach of relatively new players (and therefore more of Eve University's pilots).

The skill required to be able to overload your modules is called Thermodynamics. Thermodynamics requires:

• Engineering 5
• Energy Management 3 (down from 5 before Dominion)
• Science 4

Engineering level 5 is quite a time sink, but is highly recommended for new pilots because the extra 5% percent of powergrid makes it easier to maximize fittings on any ship. The Thermodynamics skill itself reduces heat damage to your modules by 5% per level.

Support Skills

• Nanite Operation - Requires Mechanic 5 and provides a 5% reduction in Nanite Repair Paste consumption per level.
• Nanite Interfacing - Requires Mechanic 5, Nanite Operation 3 and provides a 20% increase in the damage repaired by Nanite Repair Paste per level.

Controlling Overloading

You can begin overloading 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 overload 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 overload many modules as fast as possible. You can choose to overload 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 overloading 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 overloading is very powerful in the right circumstances.

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

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 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 overloaded generate heat. This heat builds up relatively quickly over time, and causes damage to the module, and any module next to it in the same rack. Heat damage is what limits the use of overloading and has to be balanced between the need for the extra boost, and the risk of losing the module entirely.

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) and overloading does a set amount of damage, found in the attributes tab of the info window for the module. When the amount of heat damage is greater than the module health, the module will 'burn out' and cease working until it is repaired in a station's repair shop.

Two modules overloaded, 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 overloaded 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.

This is because in addition to taking the listed heat damage in the info tab, each overloaded mod has a percentage chance to damage other modules in the rack. This "splash damage", when multiplied by having more than one module overheated, can lead to very rapid heat damage. The tachyometer-looking heat displays around the capacitor in the central HUD display a kind of damage multiplier, from 1-4, that increases the amount of heat damage taken the more heat is built up in the rack.

Some people fit offlined modules in between modules they plan on overloading 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.

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. As a rough rule of thumb, 1 minute, and 1 unit of paste repairs 10 points of heat damage. 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.
