Chad's CPU Cooler Test System Specifications



I would 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 more information.



Thermal Results




With the CPU at stock levels, the Eisbaer 240 CPU is only 4.5 degrees out of the lead. The Alphacool is slightly bested by the EK Predator at this point, and a couple more AIOs as well. Still, 49.5 degrees is well ahead of most of the pack on our chart.





With our overclock applied, we find the Eisbaer 240 CPU drops behind a few more AIOs, sealed and open loops, but again, it falls in the top third on our charts. Of course, if Alphacool had shipped the Eisbaer with 80-90 CFM fans that make your ears bleed, they may have shown better against those that show as more efficient coolers.



Noise Level Results




The pump was spinning at 2600 in all of our tests, and we are pleased to report that there was not any noise associated with it from a foot away. As for the fans, however, with them controlled to the same level as all the rest, and spinning at 1050RPM, we heard 34 dB of noise from the pair at this point in testing.




In both this chart and the one we just saw, the Eisbaer gains ground on many other coolers on the list, with the lack of noise produced to keep our processor well within safe operating temperatures.


Our fans topped out at 1660 RPM, and while at this speed, we heard only 45 dB from them. Considering most other AIOs are in the 60 dB range, a lot of potential customers will appreciate this aspect.
