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.
As you can see by the temperatures, Scythe makes a great showing in the charts. With a max temperature of 57.2° Celsius the Mugen 2 can play ball with most of the top end coolers, give or take a couple degrees; this depending on your choice of fan arrangement, whether one or two and the amount of airflow your case provides. Either way you slice it, the Scythe Mugen 2 is more than capable of handling the job it is built to do.
Temperatures with coolers are based on a lot of things and one major thing is high CFM fans. Scythe sends a 74 CFM fan that is really good at cooling as well as keeping the noise at bay. In this testing the fan was at a maximum of 51 dB during the load testing, which is a win win in my book. Not only can it cool, but it doesn't sound like a vacuum cleaner trying to accomplish it.
