The change in the spacing will create an oscillation in the amount of air that passes around the blade tips, which will create noise due to the blade tip losses affecting the pressure ratio above and below the blade. Also, if you notice, the housing is not perfectly circular. It is probably worsened by the comparatively large spacing between the blade tip and the housing. My guess would be the design of the hub spokes on the SP120Ls are one of the largest sources of noise. I run (as I think I mentioned earlier) a pair of Gentle Typhoons, and from what other people have tested, they are significantly better performance wise (for the same RPM) and make far less noise (for the same performance or RPM). its worthless having a fan on the pull side.Ĭlick to expand.From what I've heard from others the retail SP120 quiets are way better, but I have not seen them in person. but pleaseĭo some research about where fans make pressure. at idle is 28 degrees with 14 degree ambient Great cooler. and its sitting on 300 rpm and cant even hear it.

and it is beautifully silent and keeps temps under 42 at full loadĪt night I put it into quiet mode as well. So I ended up putting one SP quiet edition on the push side hooked it up to the PWM and during the day I have it set to fixed RPM of 55% which is 600 RPM. as the air has to pass through the blades to have the pressure changed! the pressure is made on the outlet side of the fan meaning buying a high SP fan and putting it on the pull side means you only draw in low pressure area. they made no difference except pull only temps went up because. I bought some SP 120mm PWM quiet editions. even on the new ones they still use the performance versions. So make sure you turn them down.ĭon't bother with the stock fans. infact having slower flowing water/fluid helps maximize the cooling anyway, at the waterblock level and for heat transfer at the radiator. on 3000, you hear cavitation and other noise. so the older ones used to just be on 90% pump speed all the time. These new GT and GTX come with variable speed pumps. I Know its a retarded way, and I was confused too!
the GT and GTX naming schemes indicate newer models. if people are looking at getting a corsair AIO.
