Built a system for a mate last month thats in need of better cpu cooling. In the case is a i5 750 with stock cooling and a Gigabyte GA-H55M-UD2H. The motherboard places the cpu socket more towards the direction of the PSU that most motherboards, so regular slim tower coolers don't seem like they'll fit. What options are out there that would fit, offer better cooling than the god awful stock cooler, and allow for some overclocking in this case?
