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

As is mostly the case with Noctua they designed a good fan here. Does exactly what I need for its size and is very quiet at the same time. Far quieter at full speed than many others. Not for the faint of wallet though.

Fairly easy installation. Quiet and well made

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

My Dell PC was getting hot playing some quasi graphic intensive games. The factory fans were just not cutting it, so after reading some reviews, I picked up one of these fans and installed it. The installation, overall, was very easy. I like the fact that they give you a splitter so that you can either add it as an additional fan or use your old fan as a secondary, which is what I did. It was harder to remove the factory fan than it was to install this one.

Great fans, super quite.

Es muy silencioso, queda muy bien como segundo ventilador del disipador.

Solid fan to upgrade noctua low profile cpu cooler

Im using it as a second fan on my NH-U9S. It moves a bunch of air for the size and it is virtually silent.

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.

A bit more expensive than most fans of the same size, but they are rather quiet and will move air effectively. I have a pair in the front of a rack-mount computer case and it does the job well, quietly.
