Review on ARCTIC BioniX F140 - 140mm Gaming Case Fan with PST Technology, Ultra-Quiet Motor, Computer, Fan Speed: 200–1800 RPM - Grey by Jeff Rhodes

First of all, I would like to address the people who are looking at this fan and are using the Corsair Commander Pro fan/LED hub. These fans will NOT work with Commander Pro. They will give some crazy rev signals and stay below 600-800 rpm. But they are of excellent quality, quiet up to about 1000 rpm, but not so annoying up to a maximum of about 1900 rpm. A window mounted air conditioner or box fan would be louder. They perfectly match the fan curves of my Asus Prime z390A motherboard and fit perfectly in my Phanteks P600S case. The supplied unpainted screws are self-tapping screws and are suitable for the job. In my case, they spin at around 1400 rpm and while I can hear them, they're drowned out by the game's volume. They lose a few revs (20-30 rpm) when the pre-silencer cap is on on my case, but they aren't pressure-optimized, which is to be expected. Despite removing the cover, they don't seem to have any issues with the fabric mesh or dust filter on the front. and female plugs so you can connect them together. 3 of them together work fine on one fan hub per MB. Overall I am very happy with them and would buy them again.
