a set amount of power goes into a video card. that amount of power doesnt change just because you put a new heatsink on it. also, the percentage of power that gets transformed into heat doesnt change when you put a new heatsink on it. this is all within the circuitry, before the power ever even makes it to the heatsink.JVM wrote:Do you have any reference to point to that states what you say about heat? In particular, a passive video card reaching 90C and video card being cooled with a load temp of around 60-65C not having a different effect on case temp?
if you have like a v-1 ultra with an 80mm fan on it keeping a card a cool 50c or so. that same amount of heat still goes into the case, its just not at the video card anymore, its someplace else in the case. then lets say you got the stock heatsink on it and it gets up to 80c. its still outputting the same amount of heat as with the V-1 ultra, except that the heat is being moved more slowly away from the card into the rest of the case.
all a heatsink does is MOVE X amount of heat from position A to position B. it doesnt change the amount of heat produced in the first place.
