Noise Level Results
Something that really is stellar on the PH-TC90LS is the fan included with it. Verifying the RPMs during the testing, at around 1050 RPM I got the result of 26dB. Considering what I remember of 80 and 92mm fans from the old days, this is much better than what most will offer.
Even when I added 12V to the fan, as in forced it in BIOS not to use the PWM controls, I verified the fan speed at 2434 RPM, and I still only got a 33dB result. So not only do we get a truly compact cooler that can handle its business, we also get one that can do it all silently and not distract you while say watching a movie.
