Noctua succeeded in designing a cooler that performs and restores some silence to your machine. The mounting system is one of the best I have used for Air Coolers, it is simple and provides very consistent mounts. Be prepared to struggle a bit with the wire fan clips if you have a large heatsink on the northbridge/IOH, but expect this for all coolers that use the wire clip fan mounting system. All in all, the Noctua NH-U12P handled the load from our 920 D0 at 1.275V (toasty little guy to say the least) under control and kept pace with high performing coolers. The one major advantage for the Noctua was the silence of the stock NF-P12 fans, which is a welcome feature.
