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 decisive moment for Sunbeamtech's innovative Core-Contact Freezer lays here. Of all of the coolers we have tested, the CCF is the best to date in load temperatures. The shocking part is that the CCF beats the Noctua NH-U12P at load even when in used with two fans. At idle the CCF is only beaten by the Noctua and that is only by a small margin. And when it comes down to it, no one really cares too much about a 2 degree difference at idle unless you are going for the world's fastest overclocked idle processor award.
In the acoustic footprint test the Sunbeamtech Core-Contact Freezer was proven to be very quiet. While we have tested coolers with a lower acoustic footprint, the CCF is relatively quiet for an enthusiast cooler.
