If you ever need a silent and long lasting fan with excellent design and looks, then look no further....because there are such quality case fans developed in Germany. Just got myself the NB-Black Silent Pro PK-3 Ultra Silent Fan a couple of months back and i am now using it as my rear exhaust fan on my Cooler Master HAF 932 build. This is a premium class fan and you guys should check out their whole range of fans especially the NB - Multiframe S-series. Check out the image gallery and a video i did with the fan on my HAF 932 case.
