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

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

replaced by tower case fan with this one. totally oversized but works great. so quite you cant even tell your pc in on.....

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

I gotta say, this fan is something else. Its my first Noctua product, and the quality of the packaging, the fan itself, and the associated manual is next level. The fan works perfectly, Im glad how short the cable is by default (something to expect for fans of this size mainly used in small-factor rigs, yet its not always the case). I ended up staying with Noctua for my other needs after using this fan.

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

Noctuas are good, but they are not the best 15mm or less, especially for the premium cost. Good for 15mm, but their 25mm? Maybe worth 15 and might buy at $10. For $20 you can do better, just put in the time to research, this especially includes their 25mm fans. Dont believe everything you hear. The more spent on advertising, the more they charge you. Also, they are listing m3/h not CFM which is 55 which is pretty good for thins. Prolimatech - otta help you get started. Quieter and almost 2 x the CFM for the cost. Sorry, cant tell you my secret 25mm $4 each, but they are out there and I have yet to find a fan better, even their own brand...besides Prolimatech, but for the cost. PM me if you have done your research and are truely at a loss.

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

Ive paired this with a

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.

Super quiet and moves air very well in tight places.
