EverCool K803-925CA air cooler heatsink
 

we can see that this EverCool K803-925AC is doing very well at our low heat setting which for an aluminium heatsink that does not have a copper core is very good indeed. Only as we start to increase the temperature higher than this EverCool K803-925AC is intended to be used at does it start to lag behind and especially so at our highest temperature test which is a rather harsh test.
