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

The fans are quiet and of good quality. The Dell 8940 computer I bought these for controls the fan speed, which means the original Dell fans were quiet too. I wasted to use the Noctua FC-1 to increase the speed of these fans = better cooling. You can’t do this on the Dell system I have. Bummer!

Works well. As described.

If you are thinking about buying this, just go ahead... I am very happy with the noise level

Fairly quiet, comes with an assortment of cables. I’m not sure if it was worth the extra money.

The best 90mm fan you can buy on the market period. Ive tried artics, thermaltakes, corsairs, etc and none can even reach the level of quiet and performance of the Nf-A9. Even at max rpms its still very quiet.

I used this fan to mod a heatsink that was making a strange ticking noise. So far so good, noise and performance are as expected.

Great fan but needed to check for noise, then return until received a quiet fan.

I bought three 92mm PWM fans to test, this Noctua NF-A9, the CoolerMaster SickleFlow 92, and the Arctic F9. The noise level on all at full speed is about the same (within 1dB from a foot away), with the Noctua the quietest, and this Arctic F9 the loudest. But, you will likely not hear any of them if they arent running at full speed.

Quiet and reliable.

Used this fan for a rear exhaust fan.
