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.
With idle and load temperatures so close together, we see that the PWM fan does a good job of changing RPMs to meet the need. The overall performance of the Gyre is decent, but nothing special. To compare it to other coolers the Gyre performs similar to the Xigmatek 92mm cooler.
In the acoustic test we see that the Gyre is actually very quiet when compared to other coolers and much better than the stock Intel and AMD coolers.
