This is an excellent case fan. The only reason why I gave it a 4.8 instead of a 5.0 is because it is a loud fan. Currently I have two of these fans in the front of my case sucking air. In the back of my case I have two Antecs that came with my PlusView 1000AMG case. This is a great fan if you want to cool your system. Installation is incredibly easy. If you are building a new system or if you just want to make your current system cooler, get this fan for a Case Fan. It is a great fan. My CPU and Case are both running very cool.
