Passive Cooldown

There is no official name for this game mechanic, so its title is pure conjecture.
 * The title for this article is conjectural.

A weapon's Passive Cooldown is the rate at which the weapon automatically expels heat that has been built up after firing the weapon continuously but not to the point of overheat. Prior to beginning its Passive Cooldown, a weapon briefly undergoes a Passive Cooldown Delay. All weapons in DICE's Star Wars Battlefront II, except for lightsabers, share this mechanic.

Passive Cooldown is often expressed as how quickly heat is expelled per second.
