I didn't read enought and bought the GPU and didn't realize it was overclocked. I'm using a Bitphoenix Prodigy and I have a optical drive so I only have two 120mm fans in it. Is that enough to keep this thing cool or is there a way to remove the overclock? I'm not into overclocking due to the risk and how much this GPU costs. Ill just be gaming casually and using it for movies and work. What should I do? Am I ok with it how it is?
