Using a Core i7-975 Extreme overclocked to 4GHz on an Asus Rampage II Extreme motherboard, we measured temperatures using Core Temp 0.99.5. At idle, the CPU’s four cores averaged 39 degrees Celsius with Intel’s reference cooler, 35 C using Thermalright’s Ultra-120 eXtreme, and 34 C using Noctua’s NH-U12P. With an eight-thread, 64-bit Prime95 workload running, the Intel stock cooler was no longer able to keep our 4GHz setup stable. Thermalright’s cooler crested at 80 C, while the NH-U12P ducked in at (a still hot) 78 C.

"More important than the NH-U12P SE2’s 2-degree victory is the fact that it’s simply a more complete package. The cooler supports all modern socket interfaces and includes two 120mm fans, all at a price that’s just slightly higher than Thermalright’s celebrated enthusiast air cooler."
