It's relatively rare to see good looking Pentium 4 heatsinks. Because the size requirements are so large for these types of heatsinks most manufacturers tend to shy away from all-copper solutions which would weigh on the PCB like a brick. But as problems occur when the transistors and other minute electronics on a silicon die begin to reach high temperatures computer stability, and even the lifespan of the processor can be affected by overheating. Thus it makes sense that manufacturers and consumers are always on the lookout for new and innovative ways to keep CPU temperatures down.

The Coolmaster IHC-H71 fulfills this role by bringing highly conductive copper, heatpipes, and a good sized fan together. The large copper heatsink features twin heatpipes coming from the base, poking out the side, and then wrapping back in towards the upper fins. The fan is a nice weighty 6000RPM, but not incredibly noisy. The big question is of course how much of an effect the twin heat pipes have on the overall performance of the heatsink, and thermal tests are the only answer to that question, so let's begin.
