Noctua NF-A12x15 FLX, Premium Quiet Slim Fan, 3-Pin (120x15mm, Brown)

These actually spin up a little higher than other noctua fans. I think they go to 1700/ 1800 rpm. This does make them a tiny bit louder at full speed but this can be fixed with a nice PWM curve setup in your motherboard or fan controller software if you prefer.

Awesome and quiet. Great for smaller case.

The fans are really silent and slim, exact what I was looking for. I recommend it.

Very slim, very powerful fan. I got this because Ive heard about Noctua being the best. Wish the color scheme was different, but they are excellent fans that come with a multitude of extensions and power modulation cords for speeds. Its quite excellent. I would purchase them again.

Can ramp up quickly and is quite loud compared to my other fans. Theres a buzzing noice

Better than stock fans lol

Powerful, silent, and effeciency. Imo also beautiful to look at.

Absolutely worth the extra cost over more common fans. Very quiet and great airflow.

Great fit for gpu bay in slim Silverstone Raven it cases. Quieter than stock.

I had to find a slim set of fans, as I couldnt fit standard 120mm fans with my Corsair H100i in a Corsair Obsidian 250D mini-itx case. These fit perfectly, and Noctua makes some of the best (and ugliest) on the market. They pull enough air through the radiator to keep an i5-6600k OCd to 4.8GHz at ~34c at idle and mid 60s under load.
