Noctua NF-A14 iPPC-2000 PWM, Heavy Duty Cooling Fan, 4-Pin, 2000 RPM (140mm, Black)

server fan with increased rpm for exhaust in my new build Noctua rules the computer fan world just the best you can get

If goes at full speed you can still heard it, but on low speed barely can heard it

I ordered these fans to replace my Corsair H115i’s stock rad fans. They sit above the top bracket to which my rad is mounted and I am speechless. I thought the idle noise I heard was the front intakes...turns out it was the stock SP140MM fans. When I swapped them, I actually put my ears up to the vent to make sure they were spinning. I am serisouly at a loss for words. Not only do these fans keep the rig 4-5 degrees cooler, they are silent. These were the best investment I have made into this rig post-build. I am very pleased by the performance.

Fan works fine, but it is far more noisy than I would like. Will be replacing soon.

Excellent fans from Noctua, they are so much better attached to my Corsair rad then the Corsair fans were. The original fans were noisy and made clicking sounds, I thought the pump was going bad.

Pros:

Excellent power not loud at all.

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.

They move a lot of air. The noise isn’t motor whine or misbalanced blades, but the whoosh of a lot of air moving. Cool things off more than a Noctua 200mm fan it replaced. They get LOUD at high speed, but even at a quieter lower speed they do well. I like to have them set where they really spin up at certain temps so I know things are getting hot before things get too hot.

This review is based on a comparison of the NF-A14 industrial 2000rpm model vs the NF-A14 standard 1500rpm pc version. I purchased this to see if I could eke out some better cooling performance at the cost of increased noise. Problem was is the type of noise this fan produces wasnt what I was expecting. I figured it would just be more air flow or wind noise but the motor itself is what is annoying. It buzzes at lower rpms and whines at speed. And the performance gained was marginal. Just really not worth it over the quiet pc version. To be fair to Noctua, they do have a disclaimer on their website about the noise of these fans, its just not the type of noise youd expect. Id recommend if performance is your only concern and you really dont mind loud fans, then skip these and grab the 3000rpm versions. Theyre even louder but theyll also cool much better.
