Test System & Test Results
TweakTown uses a different method for testing CPU heatsinks which allows for an even playing field across all product tests. We feel that by using the same ambient temperature and strict lab-like testing procedures we are able to accurately compare one product to another. More information on our testing procedure can be found in the T.E.C.C. article here.
While this isn't the best scoring cooler in the temperature chart, it still performs better than stock and will allow for a bit of an overclock as you can see. I don't think that this would tame a Q9650 or an i7 920 with 4.0GHz plus in mind. The fan just won't keep up with the heat.
On the quiet end of things the NV120 PWM does come out as one of the better performers. Noctua quiet, this cooler isn't, but not too far from it. Almost inaudible at idle and while at full load it's barely discernable over my graphics cards fan 3 feet away.
