Hello, I have a cooler master hyper 212 cpu cooler. It came with it's own fan, but it is making a hell of a lot of noise. This is the one: http://www.scan.co.uk/products/cool...-with-120mm-quiet-fan-lga775-1155-1156-1366-a It evens calls itself a quiet fan, but it is not at all. If I stop the fan rotating pc is nearly silent. I want to replace this fan with a quieter one. Can I just use a standard 120mm case fan? The fan dimensions are 120X120X25. Thanks in advance, Tom.
