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

I tried these but was skeptical in the process mainly because theyre slim... They are made by Noctua though so I figured I could trust it at least given their history and my experience with them in the past. amazingly the things have the same static pressure my noisy not so air pushing across the case Thermaltake RGB fans did for my AIO. I was going to use these fans as push then pull with 3 a12x25 behind them in the front of the case, but I wasnt in the mood of chopping the case up. the manufacturer says yeah a rad fits in top too a 240 mm which i dont see how with standard fans! I found out if your motherboard has a vrm heatsink nope... I measured though and a 360 would fit with 3/4 of an inch of clearance and I already had the little fans plus they gave me 6mm of clearance between that vrm and the radiator. So I mated them to the 360 radiator on top and wow! Im blown away by the sheer performance of these things, they seriously pull some air right out of the case and keep the radiator cool enough for any load. My case with these as my exhaust 3 mounted on top with a 360mm radiator and 3 a12x25 fans in the front keep my 2070 super boosting up to 1932mhz at 69 constant temp in any game.

I made the mistake of not getting these in PWM. So I’m stuck to manually changing out the connection cables to tune the fan speed. These fans come with 3 types of cables that correspond to the speed you want to run them at. It was my mistake for getting these as I wanted fan speed to be handled by my mono.

These are very low profile fans to eliminate unnecessary clutter in my case. They still move a lot of air and are very quiet for such a small form factor.

Very quiet, which is exactly what I wanted.

Excelent product excelent quality

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.

I got two of these 15mm fans for my Node 202 case after my GPU was getting a little too toasty for my liking. With my RTX 2080 Being 50mm thick and being limited on space these fans just barely sneak past the height restrictions in my small form factor case. Since installing the fans I’ve seen my GPU in game running at 140F instead of 195F. These fans maybe smaller then typical 25mm fan, but perform just as good.

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.

I love Noctua fans, and now we have skinny Noctua fans. DAT CLEARANCE!

Only used one of them briefly. Mainly purchased to cover installation contingencies with fitment of my custom radiator cooling kit. Doesnt push as much air as my Noctua NFF-12 standard fans.
