Noctua NF-F12 PWM chromax.Black.swap, Premium Quiet Fan, 4-Pin (120mm, Black)

They move enough air and are almost inaudible. A worthwhile upgrade to my loud Corsair liquid cooling system. These fans dont move quite as much air when run full throttle as the stock fans, but theyre close enough. My CPU temps are within 1 - 2 degrees of maximum temperature as with the stock units without the turbo whine of the stock fans. By far the loudest noise my gaming system makes now is the GPU fan spooling up, and since its buried in the case, its quite tolerable.

Just like the title says, two of the three chromaxes I ordered are failing after six months. The fans will spin up and then come to a halt and tick like a fan thats not getting enough start current, but if you unplug them and plug them back in, they will start up again. Definitely not the kind of quality Ive come to expect from Noctua. Stick with the normal colored ones, those never die.

Awesome Fans ... very quiet and very silent. superb cooling.

ok, so this was the last item I installed on my new PC build. They took forever to arrive (well Amazon forever.... 10 days). Anyways I just got them yesterday. I installed 10 of them in a Corsair Obsidian 1000D. 8 to suck air in through the front and 2 to suck air out the back. I also installed 3, 140mm sized fans of the same make and model on the top of the tower to suck hot air out. That gives me a total of 13 Noctua Chromax fans installed in my PC case. I also have 3 Be Quiet fans installed inside the case on the CPU dual tower air cooler. Thats 16 fans plus my GPU fan running inside the PC case.

The most important thing to know is that these are 4-pin fans, meaning they need PWM control from the motherboard. I initially installed these on my old motherboard that only had 3-pin connectors and these suckers were LOUD. They ran at full speed and it sounded like a server. Once I got a motherboard that allowed support for the 4-pin connectors, these have turned out to be the most quiet fans that Ive heard in a computer, and I work in IT deploying a bunch of desktops. When you *do* hear the fans, its a low hum as opposed to a whine or like a badly tuned turbo. I have been recommending these to others that I know who are looking to upgrade their builds.

Very nice fan from Noctua again! The packaging is great, and the fan itself feels extremely high quality and durable. Under normal computer use the fan is pretty much inaudible and under gaming it has a very VERY slight hum. Definitely better than the Corsair ML120 Pro fan I had before as those things were loud. My only gripe with this fan is that the cable is a bit stiff and not that long so I had to route it differently than I had originally planned. You can always buy fan extensions directly from Noctua as well and theyre relatively cheap so I wont knock off a rating for that.

Bye bye brown. I needed a fan for another build and decided to upgrade my main desktop with a black fan for the Noctua NH-U12S CPU cooler. Same quiet performance just not brown. I did miss that it only comes with 4 of each color of the vibration pads although going back and reading, I see where they mentioned buying an additional set for matching color. I did not get that the first time around. It was not a problem for me as I used the black set as the other color.

Easy to install. Color customization is easy.

I lost my packaging and got stuck with the fan after realizing how this may cool well but it has a resonant tone that it constantly produces, somewhere between a hum and just NOISE. F this, not what I expected from Noctua.

Bought this to replace a 140mm CPU fan for ram clearance issues. Works well and temps are about the same even with the smaller fan.
