Test System & Test Results
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.
In the idle testing the low RPM and CFM of the fan, as well as lack of fins shows; the Rasetsu ends up right in the middle of the group here with a 51.9°C temperature.
At full go, the Rasetsu again plays into the averages of all the 120mm powered air coolers. In reality, with the bent over, blowing at the motherboard style of cooler, in that grouping it is the second best option behind the Noctua NH-C12P SE14, yet the Rasetsu is $20 cheaper.
Noise levels at idle tested along the lines as the other Scythe coolers with the Slip Stream on them.
Same goes for the full on testing of the fan. There is a fair bit of a hum to be heard, but it isn't anything compared to some I have tested along the way.
