Summary: I bought this for my cabinet, I already have a cm 80mm and thermaltek 90mm high rpm fan-but the cooler master fan doesn't perform well in the matter of pushing out air. Thus this fan. Super-fast and pushes out air nicely. This fan looks cool also and acts likewise! Definitely is silent, which is always a plus in case you already have case fans. Prompt deliver and nice packaging by Naaptol, thanks.
