Alpenfoehn Brocken 2 CPU Cooler Review

Test System Setup




I would first like to thank ASUS, InWin, Corsair, 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.



Thermal Results




At the stock level of testing, we are quite surprised to see that the Brocken 2 is beat out by the Brocken ECO that has much less cost associated with it. While the 54.5 degree average result we found in our testing is still very respectable, we are still at a loss as to how to spin this in a pleasant manner.




When the OC is applied, the story changes slightly as we now find the Brocken 2 just ever so slightly outperforming the ECO. The 74.5 degree average here keeps well away from the throttling zone, and is within a degree or two of other nice single tower coolers that allow access to everything on the motherboard.



Noise Level Results




Here is where this cooler does stand out as a top performer though, and that is in the lack of noise dumped into the room while cooling the processor. With only 7.5 volts running through the fan, we saw speeds of 750RPM, and at a foot away, noise is almost non-existent as the 25dB result shows.




Even when we set the Wing Boost 2 140mm fans free with 12 volts of power to them, the sound levels stay consistently low. While the Brocken 2 noise levels are certainly not the best on the chart, getting into the top ten is good work in itself. With only 40 dB heard at full speed, AIDA64 reported 1200 RPM, rather than the 1100 that is specified. At this level, you can rest assured that the GPU fan will likely be much louder at load than this cooler is.
