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

Heck, they are really quiet! I use them in my custom build PC case - you can barely hear any noise. They come with extra cables and rubber mounts.

Best fan for an SFX build ever! 10/10

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

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.

I put 2 of these fans in a full tower case and they are performing beyond my expectations!!!

Was louder then I would have expected for a Noctua fan. Burned out within a week.

Very quiet, which is exactly what I wanted.

Have not had it for long, but it appears to be good. Was put off buying other much cheaper fans, since there was a high percentage of negative reviews: DOA, noisy, inefficient, or fail soon. Also, 99% of 120mm fans are 25mm or 1 thick without rounded corners, which make them unsuitable for tight spaces.

Great quality came with extra cable extenders

very good quality the only thing i wish was that it was a pwm fan.
