Heat
With Revelations part deux came a new feature named Heat. With heat came the possibility of overloading your modules for an extra boost when you are in dire straits. When you need to squeeze a few more shield hit points out of your shield booster, or you need to deal just a little bit more damage to your opponent.
However, there are side effects to overloading. Once you overload a module, it will start to generate heat. Prolonged exposure to heat will damage and eventually offline your modules rendering them unusable until they have been repaired. Heat is thus an emergency tool when you need that dash of extra power.
Heat is distributed over racks, which cover your High, Medium and Low power slots. Heat will spread over the rack causing heat damage to some or all modules on the rack. This means that you can damage many modules while only overloading one module. Multiple overloaded modules will cause increased heat consumption on the rack and faster damage to your modules. It is thus advised to tread this with caution.
Modules cause different amount of damage and can be seen by hitting show info on the module. There you can also see what you gain from overloading it.
Operating Heat
Your modules have a circle around them. If they are capable of overload, you will notice that there is a button in the top ring as shown by the picture below.

Once activated, the part of the ring will glow green indicating activation. Your heat consumption is measured above the Capacitor and lists the three racks.
Once modules start getting damage, the rest of the ring around them will start glowing red. A module will be off lined once the ring is completely red.
Heat will dissipate slowly, and over time.
