Have the BeQuiet! built in my gaming PC and let him over the mainboard (PWM - silent) run. It really does not stop him and that's a good thing. There are no vibrations to hear.
Installation is simple, since he works without screws using the supplied "plugs" (5 pieces - one as a spare). The Quatität how not expect otherwise from BeQuiet! is great !!!
Strong buy recommendation for a 120mm fan with PWM. Super: D
