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

Solid fan to upgrade noctua low profile cpu cooler

Wow, I can’t belive how much of a difference these made. I wish I could upload two videos for the before and after. I can’t even hear them from my desk and the fans are more quite then the water pump now! I should have made the upgrade years ago! (Video is of two of them running max speed and the occasional gushing is noise from the water pump for comparison!)

Great fit for my CPU heat sink.

Im using this on a mini itx (K39 case) with some overclocking, replacing the original Noctua LH 9i fan. Improved the heat dissipation by a fair amount and its so quiet even at max. speeds. The only thing thats loud is the graphics card fan . Go for it if youre in the market looking for one.

Added this to a D9L

Noctua are the best fans Ive ever used.

Very Good Quality Computer fan.

Whisper quiet, used inside server in my bedroom. Loudest thing now is my enterprise hard drive. Server runs day and night without fail.

I bought this to put a Noctua NH-U9S CPU cooler into a push-pull configuration. It works perfectly for that purpose.

Installed Noctua fans for my case and CPU on a build a couple years ago. Still cant hear the unit running. Best fans Ive ever used. Super quiet.
