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

Very quiet even when idling, as a rear case fan, at about 870 - 900 rpm and lowered case temp.

I replaced an old heat sink fan with this 92 mm fan. It’s So quiet, I have to replace the rest of the fans with noctua now too!

The best 90mm fan you can buy on the market period. Ive tried artics, thermaltakes, corsairs, etc and none can even reach the level of quiet and performance of the Nf-A9. Even at max rpms its still very quiet.

Super quiet and works perfectly

I was a bit concerned about the caompatiblity of this fan for the Dell SPX 8940. Many review has issue of Dell BIOS error with the fan installed. I also ran into the BIOS error. But with try and error, I finally found a way to install it w/o error. The XPS 8940 will alway check h/w whenever you make any changes. The Noctua fan is incompatiable with Dell, then it will give error after the switch. However, with the Y-adapter, i installed both the Noctua and the original Dell fan, and it pass the inspection w/o error. You can disconnet the Dell fan, but I use the extension cord and mounted the Dell fan to the front. The temperature of my two hard drives lowered by 5 degree C which were running very hot.

great fans but they were supposed to come new and I am missing the 4 pin y cables. please send me the missing cables and review will change. you have also been contacted via the support line on your website

Nice little fan, cannot even hear it, I should check if its even working, hah!

This fan is used as an exhaust fan on a Asus prebuild that is as loud as a car. This is my first time buying a quality 92mm fan and I am shocked how quiet this fan is. Even at full RPM you can barely hear its noise.

It runs nicely. Does what I expected it to do. Responds to UEFI adjustments. I used it in my first PC build. I had no idea what I was doing with the rubber mounts and ended up just bolting it on to the rear exhaust with screws. With an industrial 2k rpm 120mm and an rx480 i doubt this is going to be something I notice. Good 4 pin PWM fan, one of two in my system. Been a few days. Runs fine so far.

Slightly better air pressure compare with the older B9 version. It also come with rubber padding. However, once add air filter the the air flow drops to very low.
