Apart from the idle mode, most of our systems work in full load. Intel's stock cooler had, as expected, the worst performance with 71 celcius. On the other hand, Titan's Amanda had a superb performance with 52 celcius at full load, with stock voltage. I assume that this kind of performance can be achieved only with a water cooling system, however Amanda makes it possible. The Asus Silent Knight II came second with 55 celcius, while Scythe Infinity/Mugen and Noctua NH-U12F came third, but with the additional fan installed. If we don't count those models, the Tuniq Tower 120 and Zalman CNPS9700LED came third, while Akasa AK-965 and Noctua NH-U12F fourth..

Overclocking our system to 3.60GHz, will unveil more interesting details about the behavior of each cooler. This time we have a tie at the first place, Titan's Amanda and Noctua's NH-U12F (with 2 fans), came first. In the second place we find Asus Silent Knight II, Tuniq Tower 120 and Zalman's CNPS9700LED. The Noctua NH-U12F and Zaward's Vivo (2 fans) came third.

Lastly, lowering the cooler's rotation speed, we can see which cooler performed the best with the lowest produced noise. This time, the Noctua NH-U12F came first, while the Asus Silent Knight II and Zalman's CNPS9700LED second. Again coolers with PWM and Titan's Amanda results are not posted, due to reasons explained earlier.
