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

Noctua fans are of the highest quality. Been using this for some time in my custom Dell Vostro 230 build and it works just great for my liquid cooler and case fan in one :)

Extremely quiet, and moves a good deal of air

This is the most quite fan I have ever installed in a PC build. (And I’ve built at least a dozen PCs in my life). Keeps my components cool. Noctua is on a whole never level of quality. They are reasonably priced as well. Only possible complaint might be the tan and brown color and lack of RGB. This is not important to me and I like the way the fans look in my case, but I know some people would prefer black or clear with lights.

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

Top quality is an overused phrase; the best available at any price is a better description for all Noctua fans. I replaced every one of my high-end gaming rig fans (six case fans, two GPU fans - for the GPU water cooler, and two CPU fans - for the equally-incredibly awesome Noctua CPU twin tower heatsink cooler).

Pops right in. I didnt use the anti-vibration screws that it came with because I dont read instructions and I had no idea what they were. I used the included screws and there is absolutely no vibration. Almost silent and moves lots of air. I use mine as an external case fan and replaced my OEM fan. I would give it 5 stars but for some reason it has a slight delay in startup, which causes my motherboard to throw an error code on startup and I had to disable the alert in BIOS. I monitor my system temps but, for a less experienced user (who, lets be real, probably wouldnt be buying themselves a new fan, let alone a Noctua) disabling a fan failure alert in BIOS would be an issue.

No wire brackets to mount secondary fan to heatsink radiator... so the fan is USELESS!! $

Bought these thinking high quality well or over priced fans must be good. I bought these to power by usb. After finding out they have barely have any flow I use a Silver stone 1500 watt psu to see if it was lack of power making them so lame. No change they barely make any flow. I spent over $30 for these little no flow useless fans. Guess what they are silent . They make no noise and barely push any air. Money wasted. I bought a $4 usb no name brand fan to replace the useless fans and they are same size. The only thing different is they flow so good they could probley could puss these fans of the table with air flow. I cant imagine who would depend on these to cool a cpu. No time to send back so Im beat out of $30 plus. Dont believe the hype. I would rather buy fans a quarter of the price that offer better performance.I use my computers 24/7 Over the years I think one went bad. out of 30.. I really feel bad for the guy that uses this to cool a cpu. Now these useless fans are somewhere in a box forgotten about.They just remind me of being robbed.

Lo mejor que hay en ventiladores

Great fan. Quiet as advertised. The higher price is for the quiet sound and the quality of the product, which is great. The rubber corner mounts practically eliminate any vibration you might have between your case and the fan. This product also comes with several pin connectors, rubber screw-less mounts, screws, and documentation.
