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

I purchased this fan as a rear exhaust fan for my desktop since the one I purchased didnt come with one, and it does the job very well. It doesnt move quite as much air as I would like, but its darn near silent so Im very happy with the purchase.

Much quieter than the stock fan in my NAS. If your NAS uses a fan which bothers you, replace it with this one. Even on high it is only half as loud as the stock fan. My NAS is a Netgear ReadyNAS NV+.

After installing these fans I had to check my case again to make sure these bad boys were spinning. Moves air but stays super quiet.

Nice little fan with great RPMs and silent as well. Im using this for a second fan on my CPU. Because of airflow in the case, I have one fan blowing air towards the heatsink, and this fan is blowing outwards right to my exhaust fan. Since that change, my CPU temps went from 60 - 65 C with heavy gaming to 55 - 60 C.

Well made fan, quality materials. Moves a good amount of air and pretty quiet. Can be used as case ir cpu fan. Dont care for the color like other reviewers, but color is secondary to quality. Noctua makes superior fans, period.

Dropped it into my Hp 8300 Slim Factor as a replacement for the cpu fan. The fan itself is the right size, though its not a perfect fit. Quieter then previous fan, no issues here.

This fan is so quite that I can actually hear my power supplys fan now.

Works great! Came with lots of cable choices! Not as quiet as I had hoped.

Theres not much to be said here. Its a Noctua fan and you buy it because its a Noctua fan.

I used this fan to replace the 14mm fan on a low profile cpu cooler. It runs quietly and keeps an 84 watt I5 cool under full cpu loads.
