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.
At idle and load the Auras TwinW is comparable to the stock Intel heatsink. I was expecting better performance from the cooler but this is not the first time I have been disappointed with the performance of a heatsink this month.
In our Sound Pressure Level Test we see that the cooler does outperform the Intel Stock Cooler. The full 12-volt load is comparable to many of our other tested heatsinks.
