Its been a long time since we have tested a Coolermaster heat sink here at OC3D, in fact I think the last one may well have been the V8 many moons ago. Hoping to build on the success of their competitively priced cooler, the Hyper 212S, they have now released its bigger brother the Hyper 612S. Ear marked as a cooler for those of us that enjoy a silent running PC the expectations are high.... Except the noise and temperature levels we want them low! Ok I'm rambling lets just move on before I dig a bigger hole.
