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.
The CoolIT PURE is one of the best coolers we have tested to date and even holds the new record for load temps. On the idle side the modified Noctua NH-12P with two fans is still the king, but when overclocking it's the load temperature you need to be concerned with.
At first I was disappointed with the testing results in this test, but then realized that the unit was placed much closer to the meter. After I re-ran the tests at the correct distance, everything fell into place as it should. As you can see on the chart, there are very few coolers on the market that are as quiet as the CoolIT PURE.
