Product Description


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 1850 to 1400rpm. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.

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 ensure 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.
SSO2 Bearing
The NF-A12x15 features the further optimised second generation of Noctua's renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability.
Integrated anti-vibration pads
Integrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heatsinks.
Scope of Delivery
- NA-RC7 Low-Noise Adaptor (L.N.A)
- NA-YC1 4-pin PWM y-cable
- NA-EC1 30cm extension cable
- 4x NA-AV3 anti-vibration mounts
- Fan screws

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.

- Reviewed in Canada on December 22, 2017Verified PurchaseAbsolutely stunning performance. It's nearly silent at full speed, which is insane, and it's inaudible below 1400rpm. I'm using it as a rear exhaust fan on my cramped case with two GTX 1070s, and it gets all the hot air out of the case quietly and effectively. Upon opening the box I knew I got my money's worth. I also have two NF-F12s on my 240mm water cooler radiator. I am a huge fan of Noctua. With a mean time between failures of about 17 years of continuous running, and unrivaled performance, I'd recommend them to anyone. I love the beige and brown colour scheme too, a real testament to function over form. Ugly colours, but performance so good you won't care one bit.
- Reviewed in Canada on March 27, 2020Verified PurchaseI needed a few slim 120mm fans so my choices are very limited. Initially I bought one of these NF-A12x15 to try it out and as with other noctua fans, the build quality on these were outstanding. SSO bearings, 6 years warranty. Low noise adapter, cable extension and anti-vibration mounts were included. For its intended use, the fan moves a decent amount of air. You can't really expect much from something this size but this is still better than nothing. Overall, this is a good fan. It is actually not any more expensive than other alternative brands out there but the included items more than make up for the price difference. Some fans do not even come with any sort of warranty on them and for noctua to provide 6 years on them only shows how they stand behind their products. Personally, this fan worked for my needs so I ended up purchasing 2 more to complete my requirements.
- Reviewed in Canada on August 31, 2024Verified PurchaseThese fans installed easily are quite and have great cooling capacity
- Reviewed in Canada on July 5, 2024Verified PurchaseThe extra cable to lower the speed to 1400RPM was handy.
- Reviewed in Canada on January 16, 2024Verified PurchaseIt's noctua, great product as expected. Looks good too
- Reviewed in Canada on July 22, 2021Verified PurchaseUsed as a front intake fan in a Fractal Design Meshify C.
"Normal" 25mm thick fans did not fit in the lower front intake position because my graphics card was too long. This fan fit easily.
It's quiet, and moves a lot of air.
It also came with a bunch of adapters - I used the included Y adapter to control both my front intake fans with a single motherboard header.

4.0 out of 5 stars Noctua quality in a 15mm package for tight spaces.
Verified PurchaseI got this fan to wedge between my CPU cooler and PSU cables in a tight ITX build. It performs as expected and is quiet as you'd expect from Noctua. I'm not necessarily convinced that this fan would be great if you need lots of static pressure. It's more of an airflow fan.

5.0 out of 5 stars Notcua Has Another Winner!
Verified PurchaseThese are absolutely superb fans. I replaced the OEM rear case fan with one of them and added the other to the front of my Noctua NH-D15S CPU heatsink/cooler. Installation in both places was a breeze. I mounted the case fan with the included silicone anti-vibration mounts and they worked perfectly and were easy to install. The directions for using them were clear and easy to follow.
The fan I mounted on the front of the CPU cooler was attached using the extra spring clips that Noctua supplied with that cooler. Again, installation was simple and it fit the space perfectly.
Upon powering up, both fans were recognized by the motherboard and both immediately spun up to operating speed. They are absolutely silent at 800 RPM, and having the additional fan should allow all to run at a lower speed, even under load.

5.0 out of 5 stars Buy this one. Reason below but dw about it, this is the one
Verified PurchaseNever bought a Noctua before, decided to see what the fuss was about. It’s sent to me in a box that speaks of 90s quality packaging; the box is quality. I know it’s small thing but it shows they care, compared to the chinese ones I bought before that came in a plastic little baggy.
My favorite feature are the rubber fan installers they include; holds the fan in place so you can screw in the screws without worrying about it shifting around. Made a 5 minute process a 1 minute process, not something any other fan does.
Includes three different power adapters too, the value is insane.
The reason Noctua has their name is because they care. Pay the extra 5 bucks to support a company that cares about the quality of their product.
