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

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

These fans move an incredible amount of air through my radiator. Im very pleased with my purchase overall.

These fans were nothing but disappointment to me. I was told that Noctua Made QUIET fans but it appears I was wrong. These fans were Loud compared to my Case fans. The only reason I gave it two stars is because it did give good airflow in my 750D case. but other than that the fans for bad for cost and silence.

Ive purchased Noctua products in the past and generally have been happy with what Ive received. I bought 2 of these for a new computer case since I was replacing an aging Thor v2. The first one I opened was packaged right (fan cable was wrapped around and tucked into the bottom of the box), while the second was not. The second was backwards and the wire was just laying on top. Not that big a deal, but I guess I was expecting a better packaged product. Also, only one of the fans came with mounting screws. Again, not a huge deal but consistency would be nice. Overall, theyre nice fans. They are not quiet once nearing full speed, but I knew this going in so it was no surprise.

Best in class! Cant get no better product to move airflow w high static pressure out there. Worth every penny they cost!

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.

Spins at more than 2000 RPM, low noise level even at max RPM. Well built, always perfect out of the box. Many fans are great but none are as good as the Noctua 120mm. Yes they cost more, yes they are hard to find in different sizes. You get what you pay for and as an overclocker they are as important as your primary cooling solution weather it’s an AIO or an open loop. The accuracy is also very reproduce-able. When you set the fan speeds they are within about 10%.

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.

Needs a powerful PWM signal to spin, I cant daisychain the PWM through any other fans, even if Im drawing the power from elsewhere. 5 corsair fans will run off that PWM signal, but I cant run any one of them at the same time as this fan.

Love these fans! Although at 2000rpm are wind tunnels but its 2000rpm!
