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.
After testing the G-Power 2 Pro I was left with the need for more. I honestly thought that the unit would perform closer to the Noctua cooler. The G-Power 2 Pro is a very capable cooler and I would be the first to put it on the front line of a CPU overclocked system, but it was just shy of dethroning our current champ.
The cooler performed on par with other coolers in its class when it came to silent operation. At idle and mild use speeds the G-Power 2 Pro is silent. Even when the heat is on, the cooler is quiet outside of the case.
