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

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%.

So I finally finish my build and used these in push on h110i cooler and what an awsome difference. Thank you Noctua for building such great fans. Temps are down 8c from my other build and these fans are so quiet because they dont have to work as hard to push air. Very pleased.

Very quiet

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.

The product met my expectations

Very loud whisper/buzzing noise from Motor. I bought 4 for my case, I have them wired into a PWM splitter and every single one makes the same identical buzzing sound. You can hear it from about 3 feet away even. I have them set up for 1115 rpm lowest and they go up from there. The noise kicks in at about 1000RPM. I was expecting quality with these 30$ fans, the air flow is excellent, but its this buzzing sound that each fan makes. As A test I put my old corsair PWM fans that came with my h110 and no hissing. Only when these are installed I hear hissing sounds. Get noiseblockers instead

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

Crappy design

Works great all temps dropped about 18c in my Lian Li lancool 205 case. They have a hum when computer is on but not ear busting at all.

best fan quite at lower rpms and lets you really ramp them up to get huge air flow
