I had long been searching for a new CPU fan. In my PC tinkers an i7 920. Clearly there are lots of good fan but my housing (Thermaltake V9 Black Edition) has a large 230mm fan on the side, so that "normal" CPU fans were happy times too large. For this reason, I then chose this fan. I already have a beQuiet PSU and therefore knew of the good quality and the good service of beQuiet. The assembly was not hard. Although the motherboard has to be removed, but that's almost all CPU fans needed (except the housing allows mounting when installed). On this occasion I would like to warn any kids to trust on Youtube, with regard to the amount of thermal grease required. The thermal paste is only to offset the minimum unevenness in metal and in no case be an extra layer between cooler and CPU. So all it takes very little of it. I have the fan installed so that it hangs just over the RAM-bars. I was the fan in my case is not installed in any direction, but that is likely to be different in other cases. I was only a little skeptical as to whether the four heatpipes would be sufficient to derive the heat. But compared to the boxed fan I had before the following picture emerges: boxed: 42 ° C / 83 ° C (idle / full load with Prime95) beQuiet: 32 ° C / 58 ° C (idle / full load with Prime95) In addition, the fan is inaudible. The boxed fan was at full capacity relatively loud. In the beQuiet fan I hear really no difference. The only thing I still hear the hard drives :) I would buy the fan at any time and recommend it to others.
