Today Guru3D reviews five heatpipe based CPU coolers from Noctua, CoolerMaster Z600, Tuniq, OCZ Vendetta 2, Coolink. Over the past month or six several new heatpipe based coolers where introduced onto the market. And I already can disclose this .. not one single cooler was doing a below average result. So for this test I decided to go a little more extreme. We'll crank up the usual system requirements a notch by using a fairly high-end PC as we take a Core 2 Duo Q6600 Quad Core processor and then overclock it to 3600 MHz to see how well these coolers still do.
