Review on Enhance PC Cooling with Scythe Kaze Flex 120mm Case Fan - 2000 RPM, Single Pack by Sam Duppa

I ordered these fans to replace my old mix of Cooler Master, Roswell and other unknown fans to keep cooling consistent and to be honest they work MUCH better than I did for 12 -dollar fan expected. I have everything 100% via a Coolermaster fan hub and yes it is noisy but it is not motor noise as others have said, it is actually the sound of quite a bit of air being pushed through the system/fans. On one of the 6 fans, only one had an issue and this is the only one of the 6 that has noticeable motor hum. See if the seller can help me here. otherwise, GREAT FANS are definitely worth the money if you are looking for higher static pressure fans.
