My main reason for buying was mainly the noise of my standard CPU fan who simply bothered increasingly at work. I had to turn the online radio, so I tones the nerve noise and do not fall into the madness. :) After the good reviews that I've read about the Alpenföhn chunks so, I did not seem to get the cost around it and started buying the new fan for my AMD Phenom 2 X4 945 (AM3 socket) ... The incorporation took place without major problems. Even if one is a little inexperienced, you can install the fan alone, even if it can sometimes be for fumbling. The motherboard must be completely removed in order to attach it to the back of the counter-holder can again. Therefore, a little more time and rest (about 2 hours) should be scheduled during the first installation. The entire construction of Alpenföhns is huge and I had in mind despite previous dimension that he did not "Sharkoon Rebel9" fits in my case. It worked with an estimated 1.5 cm remaining leeway. The cooler is pressed through 4 screws neatly on the contact surface. The contact surface is completely covered. After switching on you only heard a barely perceptible humming noise through the fan, very pleasant. Top! And the cooling capacity varies around 30 ° in the idling mode. My boxed fan was even in idle to just 45 °. When he came to 55 °, CPU Smart Fan Target turned first really high and it was unbearable (while gambling was often the case). I can only recommend it to fans. However, it's just huge and does not fit in any case! Before necessarily measure and gather information on the Internet about the dimensions of the PC case and pull a few centimeters for Board and bearing surface. One shortcoming is there anyway: namely, the orientation of the fan is with me only up or down is possible. Actually rather bad, because most housing (including mine) but are open to the front and to the back, rarely upwards. Optimal would be if the air can escape directly. Given the good temperature values I would recommend this anyway ...
