Noise Level Results
When the PC is at idle and the PWM has control of the fans, you really don't hear much noise. Checking with AIDA64, the fans were only turning at 700 RPM and made slight jumps near 1000 if the heat did build up. This is how the SA SB-E Extreme is able to come in so low in the idle noise levels.
When the fans are let loose and spinning at 2523 RPM the noise levels jump exponentially. 69 decibels of noise is quite annoying for day to day running, but that noise comes with goodness. Even though these are some of the loudest 140mm fans I have ever used, there is no denying the temperature results that come with it.
Everything comes at a prices, and with this cooler, noise was not a concern when shooting for the stars.
