thinking of using a h60 sealed unit to cool my cpu instead of a fan, i read there just as loud as the fan fr the rad is noisy, but was going to replace it with a gentle typhoon 1850rpm, has any1 got a similar set up? its £60 with £15 for the fan, or is it better to go for an over clocked bundle (i5 3750k) and keep the fan suplied rather than faffing about?
