Yate Loon D12SL-12 PTS on BGears 120>140mm adapter
Pretty much about the same as the 140mm fans in noise level per CFM. While the 140's do have a general CFM per RPM advantage, they also produce more noise per RPM. Really not much if any difference other than a slightly different tone. Actually I much prefer the 120mm yate myself, it's smooth at all volts, where the 140mm is nice down at lower RPMs, but has issues up high with the blade resonance thing.
If the shroud effect is zero, it seems on a radiator there is little to no difference in noise level per CFM between 140mm and 120mm fans. This is probably why there is some hesitation for fan makers to go to 140 sizing...also probably why we see fewer high speed 140s. Anyhow, this 120 does great on the 140mm radiator, particularly with noise quality where it's smooth all around.
