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

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.

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.

The fan is nearly inaudible. I replaced the cooling fan on an older OTC 600w power supply on my computer. So far the power supply has not had any cooling issues with this fan. You really cant hear this fan unless you turn everything else off. In my case the case fans were much louder. Great product that lives up to its hype.

It barely spins and takes our air from my PC, I was expecting something better from Noctua. This Slim fan does not work properly, I guess I got a malfunctional one.

Best fan for an SFX build ever! 10/10

Ive paired this with a

Great quality came with extra cable extenders

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

Awesome and quiet. Great for smaller case.

Wonderful fan that, even when at Max, isnt as loud as youd think. Its more effective than the Silverstone Slim fans and the rosewell fans you can find here on Amazon.
