Noctua NF-A9 PWM, Premium Quiet Fan, 4-Pin (92mm, Brown)

I purchased the 4 pin and the flex and they work great.

It was easy to install, and it runs so quiet. Its more quiet than my RGB Corsair fans. I decided to upgrade another old fan to a Noctua, and Im confident its going to be great.

This is the most quite fan I have ever installed in a PC build. (And I’ve built at least a dozen PCs in my life). Keeps my components cool. Noctua is on a whole never level of quality. They are reasonably priced as well. Only possible complaint might be the tan and brown color and lack of RGB. This is not important to me and I like the way the fans look in my case, but I know some people would prefer black or clear with lights.

Runs quietly and produces a lot of air , about 50 cfms

Wow, this is so quiet that when I installed it to replace my foxconn 92mm exhaust fan (that was too loud and whiney) at first I thought it wasnt working. I can only hear it a tiny bit in the dead of night. It even lowered my cpu temp by 1 degree at heavy load. Im also using a Noctua NF-A8 PWM case fan on my Ryzen 3600 cpu so my HP Pavillion PC is now nearly as silent as my laptop (however my cpu temps went up a few degrees under heavy load with the lower powered Noctua 80mm fan so no overclocking with my current rig). Noctua fans are definitely worth the money for people who need a quiet computer.

Very Good Quality Computer fan.

I switched out all my fans and the CPU cooler for Noctua products. Under no load I cant hear the system at all. At full load its whisper quiet. Need I say more?

Great quality fans as always from Noctua.

Easy, quick install. Whisper quiet. I only hear the fan at the initial startup of the computer. After that, youd have no idea it was on, but it moves air very quietly. Im happy.

It works well.
