Review on ARCTIC BioniX F120 White Gaming Case Fan with PWM Sharing Technology (PST), Ultra-Quiet Motor - 200-1800 RPM by Ken Perry

Will I buy again? Absolutely! To be honest they push a lot of air out so there is some noise, especially if like me you have multiple fans. I have 8 fans, 4 of them replaced. They push MUCH more air than my previous fans that came with the case. The bearings are of good quality, play-free and rotate freely. I expect these bearings to last well above average. Fans are great! The ones I received don't have a backlight. For me that's a plus, I work and play a lot on the computer and don't want too much light to distract me from my peripheral vision. This is exactly what I was looking for. I like the ability to daisy chain them and the fact that the speed can be controlled from the motherboard. Unfortunately, my motherboard doesn't regulate the speed, but that's easily fixed with a switch, and it's not the fan's fault. However, note that you may need a BIOS update or a manual switch. Plan the required cable length when ordering. I ordered extension cords when ordering fans.
