I purchased this fan to replace the standard fan supplied my Corsair Carbide 500 housing. After years of "wind noise" of my PC I was tired of this noise and have replaced one by one all the components. After the case a graphics card "GeForce GTX760 (Twin Frozr)" by MSI, a Samsung SSD840Pro instead of a normal hard drive, a power supply "BeQuiet Dark Power Pro 10 550W" and a "BeQuiet Shadow Rock Pro" CPU cooler had taken their seats , were only the case fans to hear. And I really need to warn everyone Silent Fan ... SILENT can be addictive! A 140mm fan and two 120mm fan of BeQuiet (yeah, I can only recommend this brand and JAAA, there are other good brands like Noiseblocker etc.) were therefore ordered, and now really is absolute silence in the room. If I want to know if my PC is running, I have under my table look for the LED of the PC case, because hear is nothing. And before anyone asks, of course, the temperature values in the green area. The motherboard does not come about 34 ° C, the CPU (i5 4670K a) creates even under long hours of servitude no 55 ° C. In other words ... there were again among the worlds retrofitted and installed fans. Price-performance is my feeling after TOP, I would recommend the product.
Oh, yes ... I lied a little. In my room, it is not totally silent. The 3m remote Synology server hums softly now audible to me in front of him. But the well is still there! * Gg *
