be quiet! Light Wings 120mm PWM - Fan Noise

https://www.bequiet.com/en/casefans/3450
Overall I quite like this fan; it has a very low minimum RPM, a nice ARGB implementation, a good frame/blade design, and most importantly, good acoustics. No resonances or motor noise to be heard here. Compared to other be quiet! fans, I like the frame design of this one, the outlet side is genuinely fully square, so there is a real seal, unlike the huge gaps that are left by the Silent/Pure/Shadow Wings series.

Compared to the high-speed version, this one has 7 deeper blades, which are less swept. I expect this to have decent performance at higher impedance, but the performance of the high-speed version is probably better on radiators. On lower impedances though, this fan is going to be fine.
