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

Strongest fan and quietest fan Ive ever used. One of these puts out enough air to force air out of every grill in my PC case on full speed. However, on full speed, this thing is pretty damn loud. Its probably tons quieter than any other fan that puts out a ton of air at the same RPM, but just worth noting that if you use this above 40%, its going to be loud and your silent PC wont be silent anymore. With that, if a little noise wont bother you, two of these on a 280mm radiator would rule. Theyve got excellent flow and a super high static pressure.

Quiet and powerfull. It is a lot for a fan and they never go on sale. I run these on a h100i cpu cooler and clocked it up 1ghz per core for a whopping 56C temp during a benchmark and the fans never hit top speed.

These fan do 2 things great push a lot of air and operate at quiet speeds if set correctly.

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.

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.

Expensive for a single fan but its worth it for the silence, they are able to move A LOT of air before becoming audible.

Great Fan moves a lot of air, high pressure and even at max 2K RPM is pretty darn quiet, you actually need to listen for the fan. WHen I decide to upgrade and I think I will try one of the 3K fans to see if there is a big difference in sound. But someone who wants fan that can move air and is next to silent get these

Bought two of these, and had a problem with one of them. I contacted Noctua and within less than a week, the broken fan was replaced with a brand new one.

Good lord, how did I manage to go this long with out finding these fans! Ok so this set is a 2000 RPM, 185 CFM, 140mm fan in black with brown rubber shoulders which can be removed. This is so if you want it solid black you can buy a set of rubber screws to mount this fan with for the same silence youd get with the brown rubber shoulders if you dont like the color.

These are great cooling fans for those that dont want to RGB their rig.
