Review on Noctua NF S12A PWM Premium Quiet by Chris Shields

Very cool fan, so quiet I had to turn on SpeedFan to make sure it worked! The temperature also dropped a lot, I have a Corsair Hydro Series H55 Quiet Edition Liquid processor. Cooler" which only had a 3-pin cooling fan header and was making such loud noises (full RPMs due to the 3-pin connector) that I bought it to exploit its PWM capabilities and swapped out the fans Don't worry about buying 4 pin splitters, this kit includes many extra connectors/splitters/extenders that you don't need Great buy and well worth the money.
