Noctua NF-F12 iPPC-2000 PWM, Heavy Duty Cooling Fan, 4-Pin, 2000 RPM (120mm, Black)

Replaced all 5 fans in my PC after one failed (not noctuas). 1 of the new fans was DOA but amazons is replacing for me. New fans are good cpu temps are down 5-10 degrees under load for me.

If these things spin at over about 950 rpm, which they will, they make a loud whining noise. There’s nothing to indicate on the store page that these are server fans, and are not just a reasonably colored version of noctua’s other fan at the same price point besides a one letter difference in model name. They’ll work if volume isn’t an issue, but be aware that these are not quiet fans.

Its a fan, it blows air. These are higher RPM fans so they can get loud. At low speeds, they are quiet. Personally, I will deal with a little noise if it means that my system will stay nice and cool when I am doing video conversion, etc.

Loud. Like 60 decibels loud. Be careful

These fans are awesome. Dropped my idle temps by 5 degrees, and under load temps dropped 3 degrees. Although under load you would think the pc case is ready for take off.

Just recently received these and theyre amazing at what they do. I had just got an EVGA 360 CLC and their fans are loud even at 900 rpm so I replaced them with these and the results are just great. These are silent at 1400 rpm, and slightly noticeable at higher ranges but not even close to jet engine loud at 2000 rpm. The amount of static pressure and air it pulls is good for radiators and dust filters.

Excellent performance

Used it in my QNAP 1079Pro when I upgraded my CPU. Its a bit quieter and it moves more air to keep the new processor cool

so i ordered this because the other 140mm fan was too large to go up front on my NH-D15 cpu cooler, all the reviews says its very quit, well my fan must be faulty because it starts of quit but after pc boots up to windows it goes to full speed and is very loud, its the only fan i can hear, if you use the noise canceling adapter the fan wont run at all, contacted noctua support and havent heard from them back yet, i am hoping its just the fan and maybe i can get it replaced.

Overall very happy with these fans. the noise level is low and they do their job well. Noctua makes high quality products and these fans are no different.
