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

I bought this to reduce the fan noise from my computer. It works well, and the CPU fan is almost silent.

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

Its a very easy swap for your stock fan on a PC and it helps with airflow and esp. that loud fan noise! Very pleased with it.

Great fit for my CPU heat sink.

Replaced the fan on my NZXT G12 with this Noctua 92mm works awesome love it!

I bought the NH-U9S for my CPU a couple of weeks ago and decided I wanted a push/pull system for the fans on the heatsink instead of just having one pull fan. So I bought this fan as the second fan. This fan is great Noctua quality and is identical to the fan that came with the NH-U9S. This fan has a Y cable that comes with it. This cable is necessary in my case because I can now connect both fans to the same CPU fan header. The only other option was to connect one fan to the CPU fan header and one to the CPU op header but the OP Header runs at a constant rate....which I did not want.

It came with every other stuff. Now I am waiting for other parts which Noctua Center send it to me so I can add the 2nd fan to my NH-U9S .

Im rating this a 3 of 5 since it should have just come with the NH-U9S and Noctua didnt even ship the appropriate fasteners with the NH-U9S, when I bought that. Great fan and great assembly overall. I just dont like how Noctua complicated the product.

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!
