Hey guys im using a Powercolor HD6950 1GB and im trying to find the cheapest way to water cool it. i thought of getting a H80i CPU cooler and see if i can use it on the GPU or not. but this would be the first time watercooling so i pretty much have no experience whatsoever so im relying on the PROS on how to do this the cheapest way possible. will one 120mm rad give enough cooling? or do i need more? i dont OC cuz the games i run are not so demanding and does not get the heat up too high. maybe 60 celsius max on Payday 2 on a hot afternoon. so guys. it would be great if i get an insight whether using a cpu waterblock on a gpu wont be a prob or not, and whether the rad is enough to provide sufficient cooling for the waterblock.
