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

The best fans on the market for noise control, precise operation and long lasting use. These fans move more air then others of the same size. The computer designed blades cut down on fan sound.

Run Silent! This fan does exactly that and more, draws more air out of my case! Excellent craftmanship and a quality product.

I have a small, 6-can thermoelectric (Peltier) cooler 'fridge' and the original fan was dying on it. I found this as a replacement. It has the same physical dimensions, a greater CFM flow rate, pulls less current and is quieter than the original fan was. A replacement fridge would have cost from ~$40 to $80 and replacing the fan cost $16.95 so, pretty good deal. It came with a 4-pin extension cable. It has rubber mounts at the corners which, I'm guessing, help with vibration (noise). Looks exactly like the picture and seems to be a quality piece of gear.I cut the cable at the old fan and pulled it out. I used the extension cable (in case I want to use the fan for something else later), cut off the end and soldered the black (ground) and yellow (+12v) wires to the black and red wires in the fridge. Voila! Back in business. The speed control is done by using the PWM wire (blue) and if you don't hook it up, the fan runs at full speed. Actually, I'm getting a 2-for-1 bonus on this fridge: my basement office is cold and it generates a small amount of exhaust heat so, that helps too.

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.After a good cleaning and installation, my PC was running cooler immediately and when I played my game, it was not running nearly as hot. This led to me purchasing another and adding it to the front of the case to bring in more cool air.The fans are super quiet and the quality is definitely superior to the factory Dell fans.For the price, this is a great and easy upgrade.

I bought a 92mm and 80mm Noctua case fan and so far it really made a difference in terms of noise reduction. I switch Noctua fan with my old one and i thought my PC died on start up because of the sudden drop of noise after 1-2 second of starting up. I can actually hear what is happening inside my PC now due to the fan being almost dead silent.It feels very weird because i never had a Desktop PC this quiet before.The Installation was easy and straight forward. It still comes in a nice looking box. The fan comes with a cable attach, also comes with an extension cord if you need the extra length, the noise reduction cord which i used for both of the fans and really made a huge difference. Along with a few other things. There was no instruction manual (maybe there was) but that was not needed. All you do is plug the fan cord into the noise reduction cord if you want to use it and then plug that into the 4 pin fan slot on the motherboard. Everything should fit together nicely, not much force is needed plugging things together. It comes with 4 screws, use a screw driver to mount the fans in place.This is not really a problem but as people know the color of fans really does not match with everything else. But i don't really look at my CPU so it not a problem for me it. They do have black now or starting to sell black color Noctua Fans. My gaming rig is not big size so these fans handle it fine. The box says a 6 year warranty so that is a plus.Overall i am very impress with the presentation and the quality. It made me want to write a review for it. The CPU noise compare to before these fans is night and day. I never realized how long my CPU noise was before using these fans. Of course this is the first day i am using them as i am writing this review so take it for what you will. Hopefully these fans will last me a good few years at minimum.

Great quieter and my pc runs cooler.
