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.
At idle, the Yasya puts up a top five performance. Now, just to explain a bit, in order to keep things fair and level, I took the fan controller and set it to "high" and left it there. We control the fan and CPU voltage in our testing, so it was the only way I could compare apples with apples.
The same settings were used for the load testing and the Yasya and the 110 CFM of awesomeness didn't disappoint. The Yasya pulls just ahead of the Noctua NH-D14 and falls just short of the similarly priced Zalman.
Again with the fan controller maxed and our standard voltages applied, the 38 dB of noise level is quite reasonable. This number is completely subjective with a controller in play. If you don't mind a few degrees increase, you can set the fan to a basically inaudible level.
At a full 1900 RPM the fan is still very tolerable, not the worst by any means. To be honest, I expected it to run a fair bit louder judging by the specs of the fan. At load you can again set the controller as you would like, but there is a more dramatic cost of temperatures at this level; some four to five degrees.
