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

Very pleased

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.

Honestly I did not know what a quality fan was.........nice, nice , nice, ugly, but nice....

Great as always!

Great quality fans as always from Noctua.

Im currently in the process of building an ultra small expandable PC, and I had purchased a Noctua NH-l9i cpu cooler. I had been able to achieve a stable clock rate of 4.6 GHz, unfortunately in testing the cpu would hit the thermal throttling point. I wanted to see if I could push the overclocking boundary a bit, so I replaced the thin fan with this one. Theoretically, this should have worked. This fan has a higher CFM rating as well as a higher static pressure rating. In actual use, this was not the case. In the end, Ive returned to the thin fan. Now Just because this fan didnt meet my particular needs, Im not knocking it too much. If what you need is a smallish fan to quietly move lots of air, this will do the trick nicely.

Super smooth and quiet cpu fan.

Im using this on a mini itx (K39 case) with some overclocking, replacing the original Noctua LH 9i fan. Improved the heat dissipation by a fair amount and its so quiet even at max. speeds. The only thing thats loud is the graphics card fan . Go for it if youre in the market looking for one.

I like Noctuas fans, but I knocked off a star because they are so high-priced.

Great fan for “lighter” applications. It did not move enough air (rpm too low) to keep my ram cool in my HP xw8600. My ram was baking at 200 degrees, and I don’t know what my mobo needed to do to get this fan to go above 1070 rpm to address the situation.
