Noctua NF-A15 PWM, Premium Quiet Fan, 4-Pin (140mm, Brown)

Replaced my old cpu fan with 2 of these bad boys. Very nice fans, they move alot of air and are very quiet.

This fan ( and the whole unit ) actually WORKS to cool off a Threadripper ( 3960x, 3070x ), since I did not have any decent water cooling for ZEN2 artchitecture. I have not tried the IceGiant though - because it think its WAY too big. One note,... the Noctua fans DONT allow you to put in ALL ram. But the IceGiant will.

Highly recommended. This is a top-notched product.

This fan is quite and has a lot of power of moving air. It 4 pin (pwm) fan makes it excellent for it to be attached to the mobo if you dont have a fan controller.

Spins faster, is quieter, and better preforming than any fan Ive ever had.

I dont have alot of cpu fans to compare but, this thing works very well. I bought 3 120mm for my case intake 1 140mm for exaust. These are very quiet fans. I also have the cpu cooler. I get temps lower than some loops i have seen. Running R73800x at around 33c :) I also get over 4.5 boosts:)

Great, quiet fan. Stock color is the cheapest I could find, though not desireable for me. Oh well. Function over fashion.

I use in conjunction with a Noctua NH-U14S and it worked very well. I also have 120 mm Noctua fans and they are also very quiet. By comparison the Corsair fans in my 900D case are noisy.

I have a Noctua cooler and added this for a push pull set up. Works well. No complaints. Noise level is really good to.

Just installed this as a case fan to replace an ultra sleek (very thin) from a different manufacturer. Needed a thin fan to fit on the side panel of my case but got annoyed with the noise. This fan is rated for better air movement and pressure than my previous fan and you can definitely feel it. Best of all ... ITS WHISPER QUIET! Noctua has me sold. All my future fans will be from this company. And as an added bonus, when building your own computer warranty is not something to be overlooked. This one has a 6 year. Would definitely recommend this!
