Noctua 120mm NF-A12x15 PWM 1850RPM Fan
Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua's AAO frame, the NF-A12x15 is a highly optimised, premium quality quiet fan in size 120x15mm. Its 15mm slim design makes the NF-A12x15 ideal for space-restricted applications such as low-profile CPU coolers or HTPC cases. The PWM version sports Noctua's custom-designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise Adaptor to reduce the maximum speed during PWM control from 1900 to 1700rpm. Its superb running smoothness, reference-class SSO2 bearing and Noctua's trusted premium quality make it an elite choice for the highest demands. 15mm slim design Having a thickness of only 15mm, the NF-A12x15 is much slimmer than standard 120x25mm fans. This makes it ideal for typical slim fan applications such as low-profile CPU coolers as well as for freeing up space by replacing standard 120x25mm fans on tower coolers, radiators or in PC cases. Metal-reinforced motor hub With many larger-diameter slim fan designs, the shorter axis and bearing lead to a reduced running stability and lifespan. The NF-A12x15 uses a metal-reinforced motor hub, a measure typically found in high-speed industrial fans, in order to guarantee Noctua's signature stability and longevity. Flow Acceleration Channels The NF-A12x15 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.

Works fantastic and silent. Wouldn’t even know it was on at idol. My ONLY recommendation to Noctua is to also provide longer screws compared to the short ones they do provide.

Best fans for radiators. Brought my cpu temps (i5-13600kf) down 5 degrees. Kinda ugly but its ok

Thinner than the normal 25.4mm fan, just 15mm, for those tight spaces. Has the 4pin PWM connector instead of running at a fixed speed (3pin.) Max rpm is about 1850. It is very quiet at these speeds. The only complaint I have about the fan is that I wish it would spin at a faster rpm, maybe even 3000, and let the motherboard slow it down to 1800 when needed. This way it would move more air than it does now. I like that it's quiet, but I would also like more airflow.
One place in my HTPC case I did not have space for a normal fan, and this slim one was a good fit. It is very silent, and seems to be working good. Noctua always knows what they are doing. My system is temp controlled, and when I do normal light duty tasks, I can not hear my computer. Reccomended
Best fans you can buy. Worth the extra cost, the added accessories are great too, include a Y splitter + extension cable
As title - these looks a feel really high quality and are almost silent even on full. Comes with splitter, extensions, everything to fit in most cases.
Replaced the fans on my NZXT Kraken X53 with these so that for the same airflow it was quieter, and has more space in my IQUNIX ZX-1 Mini-ITX case between the radiator mounting plate and the fans. Previously there was no spacing and it was causing some fan whine with the NZXT fans. Moving to these gave me the ability to create that gap. These are also just generally quieter.
I just tried to replace my Corsair SP120L fans on my H80i GT. I'm afraid, they can't keep up with the SP120L high performance fans. They're still very quiet at full pelt but the SP120L's have the extra power that results in a 5degree+ lower temperature on heavy loads albeit with jet engine type noise levels. My SP120Ls very rarely went to full load but my A12's run close to full speed at the merest twitch of the CPU being used. These fans are probably best suited for those that want very quiet fans at medium CPU loads. They're unfortunately not 'quieter' high performance fans. I probably should have gone for the NF-F12's. Ah well, I'm sure I can find a use for them on a different machine where they will be more suitable.
