After the fixed with self-tapping screws, very quiet case fan atelco my computer needs to be replaced after 2 years, I hit upon the ARCTIC fan. Although the cooled fine, but when audible noise of extremely annoying frequency. Now he is in the tub and by a Be Quiet! Shadow Wings fan replaced with screwless anti-vibration mounting. It is again a haven of peace -almost even better than when Neurechner.
