Noctua NF-S12A FLX, Premium Quiet Fan, 3-Pin (120mm, Brown)

These fans run well and are quiet, come packaged with all the adapters and accessories that would be needed

i had to take apart a few things due to my case construction, but works great and is quiet

These fans are made by an Austrian company dedicated to air cooling, and the quality of the engineering is unsurpassed. Each pack includes all adapters and mounting accessories necessary. The fans push a lot of air, are very quiet, and, in my experience, outlast all cheaper fans (the latter start to rattle after a few months of use).

I tried the Arctic F12 Pro that a lot of other people used but I didnt like that the air direction and CFM was different than the factory fan (although it probably doesnt matter). Instead I tried this one, which is a normally shaped muffin case fan so you can mount it as an intake fan like the stock.

When I originally built my computer I cheaped out and bought $5 fans and regretted that choice for about a year until I bit the bullet and bought two Noctua fans as case fans. They are worth every penny! Super quiet with very premium build quality. Ive had them for over three years now with no issue and theyre just as quiet as the day I got them. Dont make my mistake and invest your money in premium fans, your sanity will thank you.

Great cooling fan, though I have yet to see just how long it actually lasts, but based on the built quality (and the six year warranty), I dont expect longevity to be an issue. The fan is quiet and stable with little vibration. It comes with two resistors that plug in-line to reduce the fan speed if needed, a long extension connector, a 4-pin Molex connector, and both screw and rubber mounts. Unfortunately, these fans are a tad expensive, making them difficult to use on a regular basis. Also, I dont care for the over-the-top packaging. How about some bulk versions and reducing the price on these?

Very quiet...very satisfied

Not much point in adding to what has already been said about these fans. Massive airflow and almost silent. Great buy if you looking for a fan that wont be pushing through a radiator.

My case was generating more heat than my CPU heatsink was able to deal with, so I installed this as a secondary fan. Quiet, easy to install, and has kept my temps nice and low

Just got these and they are wonderfully quiet. I got two fans to replace the two loud fans that I had already. While I really like how quiet it is, I have notice some changes in temps. To be fair, I put on the Low-Noise adapter on it so it isnt running at the full RPMs it can be. That being said Im only seeing 3-4 degrees higher overall while being nearly silent at about 800 RPMs while my other fans that I replaced were extremely loud and ran at 1500-1600 RPMs. I will take that ratio and If I really get fed up with the 3-4 degrees temp difference I will take off those adapters. The overall temps for the CPU is at the high end under moderate load 40-45 degrees Celsius. A lot of temp change in the CPU comes from the hot graphics card right under the CPU. This is with i7-2600K 3.4Ghz CPU and a Radeon HD 6950 video card (this card runs really hot, even under light/idle use).
