Alpenfoehn Brocken ECO 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




While we expected a couple of degrees of performance boost on the Sella with the Brocken ECO, our stock testing shows that our fifty-three degree result is right in line with the Sella. The performance gained from a second fan shocked us a fair bit. Even with this low level of power going to them, once the second fan was added we got the results down to 51.75 degrees, which is only about five degrees away from the best cooler money can buy currently.




As we applied the overclock, the gap widens from first place, but the results are still admirable for a 120mm fan based contender in this list of monsters. As shipped, with one fan, the results were 74.75 degrees. With the second fan added, we notice a slight drop in performance, with only slightly more than a degree change in overall temperatures.



Noise Level Results




With 7.5 volts going to the fans, and a reported speed of 955 RPM, we found the fan only produced 32dB of noise at close range. From any distance in a closed chassis, this fan will likely not be the loudest fan at idle.




Once we allowed the fans to spread their wings with 12 volts going to them, we found them spinning at 1470 RPM, and delivering 50dB of noise into the room. Of course, this last number is quite large when it comes to coolers these days, but the reality is that this range of noise will only be heard on the hottest nights, or in the longest of gaming sessions.
