be quiet! Pure Rock CPU Cooler Review

Test System Setup




I would first like to thank ASUS, InWin, Patriot and Fractal Design for supplying products for me to test with.


To see our testing methodology and to find out what goes into making our charts, please refer to our CPU Cooler Testing and Methodology article for that information.



Thermal Results




As we allowed the system to idle, we saw a temperature of 27.25 degrees, which is right on the average for most air coolers. When we loaded the system at stock clocks, we found the Pure Rock delivered us a 54 degree result. This is still hugely better than the stock cooler, and for its cost in comparison, the top of the list is only some 10 degrees better for maybe ten times the investment in some cases.




Moving to the overclocked settings, we were now seeing an idle temperature of 29.75 degrees, and as we applied the load, the temperature climbed a bit. This left us with a 75.42 degree average, and while not tremendous against the list of coolers here, for a 130W TDP cooler, it will handle anything that the intended market for this cooler can throw at it.



Noise Level Results




With only 7.5V applied to the fan, we saw a maximum speed at this point of 1150 RPM. At this speed, our meter was reporting a minimal 26 dB of noise from a foot away.




What we like even more, is that even allowing the fan to do its worst when it comes to noise pollution in the room, all this fan could muster was 38dB, and our fan was reportedly running at 1715 RPM; slightly over spec.
