At 126mm x 57mm x 157mm (5" x 2.2" x 6.2") the PH-TC12DX heatsink is tall enough to cause some problems with small cases but is tall enough it will not interfere with your RAM like some other large coolers can.  With only two screws to secure the heatsink [H]ard|OCP had no troubles installing it on the motherboards they tested it on.  When they tested its ability to remove heat they were more than impressed, with a pair of fans this air cooler outperformed Corsair's H80i, a feat made even more impressive by the fact that it operated more quietly as well.  At $60 it is also cheaper and well worth considering on your next build.

"Phanteks has high hopes for its sweetly named PH-TC12DX CPU air cooler. OK, maybe not that sweet, but with a patented "Physical Antioxidant Thermal Shield" and "Cold Plasma Spraying Coating Technology" technology this thing has got to be greatest heatsink and fan combination ever made, right?"
