The CoolerMaster Hyper TX 3 delivers results that are much better than the stock cooling solution on all counts. The idle temperatures range from 10 degrees Celsius lower on the idle overclocked test to a massive 25 degree Celsius improvement while under load in the overclocked testing. That is a 30% improvement! At the stock clock speeds and voltage the Hyper TX 3 still delivers a 19 degree Celsius improvement over Intel's cooler. The Noctua and Thermalright Coolers are much more capable when the voltages start creeping up but then again the price is quite a bit higher for that cooling performance.
