Noctua delivers the NH-U12S for testing - one of a pair of new tower coolers with some new tricks up their sleeves.

Noise Level Results

With one fan on the tower, and the PC at idle, the fan will spin near 400 RPM, and is dead silent unless you can get your ear into the flow, and you can hear the wind pass your ear - that's it.


In the middle of testing is where I took this reading from the cooler, and the fan was much closer to 800 RPM to get the 26dB rating.

What sort of shocked me is that I either got special fans with this cooler, or there may have been an issue with my original NF-F12 PWM fans. While testing the NH-U12S with one of the NF-F12 PWM fans I was sent this time, I only got to a reading of 40dB with these tests.
