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.
