Noise Level Results
In our idle configuration I found the PH-TC14CS to bit a bit quieter than its predecessor, the PH-TC14PE. Again like with the Noctua, the directionality of the flow being blown at the motherboard, it deadens some of the noise that tower coolers dump right out the back.
The same thing happened once I had 12V going to the fans, they just didn't make the meter go as high as the same fans on a different cooler design. That being said 52 dB is not that bad and most enclosures will make the slight hum I heard from them be less apparent once the door is shut.
