Testing of the Scythe Rasetsu

Over time, we’ve found that we have been able to get a better overclock out of our i5 655K (4.2GHz) with a very respectable 1.4v, so we used this for testing the Rasetsu. To do so we allow the system to sit idle for one hour and then measured the temperature. Afterward, we load OCCT and run a 30 minute bench session with priority set to high, then recorded the temps at the end. Each core was recorded for more detailed performance information. 

Results

In the testing we saw the Rasetsu out perform the older Yasya by just a degree or two max. Besides the cooling numbers we also realized that both had their own advantages over the other. The Rasetsu because of the way the fan is positioned cools down the surface of the motherboard and surrounding components; however, that also means that the heat stays in the case, since the Yasya blows air out the rear of the case where the Rasetsu does not. And lastly, the Rasetsu can fit in the some cases where the Yasya can’t not due to its height.
