Deepcool RF120 RGB - Fan Noise

Generally, I quite like this fan. It has a good blade design, good frame design (no huge gaps, wide compatibility), and doesn't have annoying resonances/ticking. On top of that, the RGB is quite nice, and this is all at a reasonable price, as Deepcool products tend to be. Keep in mind though that the RF120 is 12V RGB (4 pin) - if you want 5V ARGB, you want the CF120, which is otherwise the same as this. My particular unit is from a Deepcool Gammaxx GT RGB cooler.
