So I have read about 10000 threads and still cannot make up my mind on which heatsink to use. I bought a San Ace 120X38 today to use on the heatsink but not sure what to go with. I have the megehalem right now but am not 100% sure it will fit this board with the Fan. I can get the Venomous X and not 100% if that will be a good heatsink. What is everyone who has this MB using when overclocking?
