> 3 dayThe low profile decent makes any system look aesthetically pleasing especially compared to a larger profile cooler. Better than stock Intel coolers but not as effective as a larger budget cooler. Ultra quiet!

> 3 dayLove these fans and the extra accessories it comes with. They are premium fans and you can connect them to your motherboards 4 pin connector. These have a 3 pin input since the models are not PWM. They are FLX if you connect them straight thru the motherboard they will run high and you will hear some noise. I say full load they will sound like your pc stock fans at medium load or ps4 in loading screen just starting to spin. These types of fans do come with 4 different cables

Greater than one weekOnly 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.

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 FLX version provides 1850/1400/950rpm speed settings via the supplied Low-Noise Adaptors in order to allow full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation. 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 ChannelsThe 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 bearingThe 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 padsIntegrated 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
|
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.
