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

I replaced the stock fans in the two XEONs of a Supermicro motherboard. Very quiet, keeps CPU temp at 40C during memtest86_

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.

Dell shipped the worst, loudest stock fan in my gaming XPS. It would drown out everything and I cant believe they would ship a fan that loud.

Quiet smooth efficient

Well built, very quiet

Excellent fan-super easy to install dropped my overall Temperature down by 10 degrees! Also this fan is decently quiet (About average when at full blast) with a great airflow.

Noctua has shown me through 4 fans and a Processor Cooler that they are capable of letting my PC run extremely quietly and very well cooled with relative ease. My only hope is that the lifespan matches the quality.

Very quiet, this replaced an old 92mm fan on my CPU cooler in my HTPC. Im seriously considering swapping out the case fans with Noctua.

No noise, I have to look to see if it is running. Highly recommended!

I heard these fans were quiet, but I did not expect it to be this good. Same RPM as a Be Quiet! brand and I barely here the Noctua compared to it. Just holding and touching it, you feel the difference in quality. One big difference between Noctua and Arctic is noise and also accessories. Both fan brands have short leads, but come with 2 different length extension and a splitter. Noctua is now my brand!
