In judging the risk of heat damage '''rack heat is more important than the extent of damage already sustained''' and '''the rack heat indicators can matter more than heat damage on a module button'''. If a rack is completely cool, it is usually safe to overheat for a cycle or two even with quite damaged modules: sometimes modules take no damage at all from a single cycle of heat when the rack starts out entirely cool. If, by contrast, a rack is very hot, it is quite risky to overheat even a module with little heat damage, as at high rack heat levels, damage will stack up very quickly. | In judging the risk of heat damage, '''rack heat is more important than the extent of damage already sustained''', and '''the rack heat indicators can matter more than heat damage on a module button'''.

Since the proximity of modules to each other affects their risk of heat damage, '''spreading out and separating active modules in a rack can mitigate heat damage'''. | Since the proximity of modules to each other affects their risk of heat damage, '''spreading out and separating active modules in a rack can mitigate heat damage'''. | ||
