ARCTIC BioniX F120 - 120 mm Gaming Case Fan with PWM Sharing Technology (PST), Very quiet motor, Computer

I really enjoyed these I order 2 120's and 2 140's however my CPU isn't good enough to run all 4 fans. However, I was able to keep one installed and just the one alone works great really keep the temperature down as is really quiet I would recommend.

Works. Works well. The motherboard controls the speed so its not super loud.

Would I buy again? Absolutely!To be fair, these push a lot of air so there will be noise, especially if you have several fans like I do. I have 8 fans and replaced 4 of them. These push a LOT more air than my prior fans did that came with the case.-The bearings appear to be good quality without a bunch of slop and turns freely. I would expect these bearings to have a significantly better than average life expectancy.-The fans are beautiful!-No lights on the ones I got. To me that's a plus, I work and play a lot at my computer and I don't want a bunch of light distracting me from my side vision. That's exactly what I was looking for.-I like being able to daisy chain these and the fact that the speed can be controlled by the motherboard. Unfortunately for me, my motherboard isn't adjusting the speed but that's easy enough to fix with a switch and it's not the fault of the fan. Just keep in mind that you may need a bios update or a manual switch.-When ordering, plan out the length of the wire leads that you will need. I ordered extension cables when ordering the fans.

Quiet, work well and great flow. Excellent purchase!
