Frequently Bought Together
Product Overview Specifically conceived for pressure demanding applications such as CPU cooling, the classic NF-P12 120mm fan helped to found Noctua’s reputation as a top-tier manufacturer of premium quality quiet cooling components and still impresses users with its exquisite quietness and superb performance.

The new PWM version features Noctua’s novel, custom designed PWM IC for fully automatic control and ultra-low power consumption. Equipped with Noctua’s signature SSO bearing and topped off with a 6 years manufacturer’s warranty, the NF-P12 PWM is a proven premium choice for the highest demands.
Features Proven NF-P12 Design
Tens of thousands of quiet cooling enthusiasts swear by Noctua’s classic NF-P12. Its impressive quietness, excellent performance and impeccable, time-tested quality made the P12 a default choice for 120mm quiet cooling.

Pressure-optimized Nine-Blade Design
Specifically developed for high-impedance applications such as CPU coolers, water-cooling radiators or cases with tight fan grills, the NF-P12 PWM provides outstanding pressure and airflow performance. button

Vortex-Control Notches
Noctua’s signature Vortex-Control Notches split up trailing edge vortices and thus spread the fan’s noise emission over a wider range of frequencies. This measure makes the NF-P12 PWM sound more pleasant to the human ear. button

Custom designed PWM IC with SCD
Supporting fully automatic PWM speed control, the NF-P12 PWM uses Noctua’s novel, custom designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at lower speeds. button

Ultra-Low Power Consumption
The NF-P12 PWM draws only 0.6W, which is more than 50% less than many other PWM fans. This doesn’t only make it eco-friendly but also cuts down the electricity bill: Compared to a typical 2W fan, this allows you to save about half the price of the NF-P12 after 5 years of continuous use.

Low-Noise Adaptor
The NF-P12 PWM is supplied with a Low-Noise Adaptor (L.N.A.) that reduces the maximum fan speed from 1300 to 900rpm. The L.N.A can be used either to run the fan at a fixed speed of 900rpm or to cap the maximum speed when using automatic PWM control.

Extensive Cabling Options
The fan’s short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and a 4-pin y-cable allows to connect a second NF-P12 fan to the same PWM fan header for automatic control.

Combining the proven concept of hydrodynamic bearing with an additional magnet that supports the self-stabilisation of the rotor axis, Noctua’s time-tested SSO-Bearing technology has become synonymous with supremely quiet operation and exceptional long-term stability. button

6 years manufacturer’s warranty
Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-P12 PWM features an MTBF rating of more than 150.000 hours and comes with a full 6 years manufacturer’s warranty.

The modern PC is potentially a mass of heat output and heat production hot spots. With CPUs rated at more than 100W of heat output, single graphics boards carrying similar ratings (and people want to run two!), multiple hard drives the norm, lots of memory and mainboards covered in heatpipes to combat toasty core logic and PWM circuits, a PC appreciably warming up a room when it’s working hard is no joke.

Watercooling for the PC has been around for years in some form or another, for at least as long as Scan have been in business, with basic physics defining why you want to use it. That means for air cooling, to cope with increasing temperature in the heatsink you need to move the air across it faster. That is why thermostatically controlled fans in your PC will turn faster the hotter something gets.

Anybody who has been near their share of computer systems will appreciate that not all systems make the same amount of noise. There are a number of reasons for why this is so. Firstly, a computer makes noise for different reasons. Generally, anything mechanical is going to make noise.

120mm Noctua NF-P12 PWM Quiet Cooling Fan SSO Bearings is rated 4.9 out of 5 by 8.
Rated 5 out of 5 by from Best fans money can buy. They're not cheap but if you want quality, Noctua are they only way to go. This was one of the companies originally released fans and are still going strong! Their PWM ICs (the chip inside the fan that controls it speed) are the best in the market. They give you the widest control (this fan for example can operate as low as 300RPM) and unlike other manufacturers do not emit switching noise. I found the sweet spot for airflow vs complete silence at idle to be around the 600RPM range. Performance at 1300 RPM and static pressure are also great. I have 3 of these in a M-ATX build enabling me to push its I7-4790K to 4.7GHz (see the attached images) using a custom PWM controller I made out of an Arduino board, in addition to some fan controller software I wrote. I've bough 6 of these now over the last 7 years (for various application such as heatsinks and case cooling) and have yet to have a problem with any of them. The only downside is their colour scheme but If you're like me and prefer function over form, you can't get any better.

Rated 5 out of 5 by from Great fans Not cheap or the best color scheme tbh, but they work really well and are very quiet unless you run them at full tilt, even then they are not that loud compared to some.

Rated 4 out of 5 by from Using two as push pull on radiator. These fans do a good job at keep temps down. I don't use my PC to its full potential or for gaming. So for me they ar ideal. Good temps in a push pull configuration and very quiet when not under heavy load. I have options via the mobo software to turn them down as they ar PWM so even then, I can keep it quiet and still get good temps. All in all, really glad I choose them for my setup. Prompt next day delivery and services A* by Scan as usual.

Rated 5 out of 5 by from Excellent quality PMW fan, especially for closed-loop radiators. I used two of these in a push/pull configuration for my Zalman closed-loop CPU radiator (replacing the original single Zalman radiator fan). Air flow was less then the original Zalman fan (it could spin at 1800rpm), but a couple of these run at 1300rpm (PMW enabled) each and cool my overclocked i5 3570k CPU at 4.4GHz with ease. The processor core never goes over 75c even under 1-2 hours of CPU stress testing (Intel Burn Test). Note to anyone using/considering a closed-loop water system (i.e. Corsair H80i) - Temperature/noise reductions will nearly always be better by using a pair of quality low-noise fans like these over a single fast-spinning 'push' fan. I recommend these fans are their quality is top-notch and the box contains my cables and plugs that should cater for any situation.

Rated 5 out of 5 by from Simply The Best! Bought 5 of these for my NZXT Switch 810 alongside 2 other noctua's for the H100i 7 in total , the result ? near silent & great low temps the build quality of these fans is top class thus i would highly recommend this item. I also leave a little tip for switch 810 owners Dont use Fluid Dynamic Bearing fans on the hinged fan brackets inside , after a while they will start to get noisey as they dont like running at an angle , No such problems with the Noctua.

Rated 5 out of 5 by from Silence Is Golden I have one of these on my Coolermaster Hyper 212 EVO CPU Cooler, one as a rear exhaust and one blowing in from top of the case. I also have 2x 140mm NF-A14 PWM as front intakes and with all of them running I can't hear a thing. My Motherboard is at 27C while my CPU is at 34C at idle. The one on my CPU is only running at less than 20% @ 223rpm. The one on top of my case blowing in running around 22% @ 281rpm. The rear one is running at 50% @ 650rpm. My two front intakes are running at around 50% @ 850rpm. My system consists of the following:- Corsair Carbide Series 300R case. Asus Z87-PRO USB 3.0 Motherboard . Intel Core i7 4770K Quad Core CPU 3.50GHz. Corsair CMY16GX3M2A1866C9R Vengeance Pro Series 16GB (2x8GB) DDR3 1866Mhz CL9 XMP Performance Desktop Memory Kit Red. 2GB Asus GeForce GTX 660 DirectCU II OC Nvidia Graphics Card. Pioneer BDRW 206D. Crucial CT128M4SSD2BAA 128GB M4 SATA III 6Gb/s. WD My Book 3 TB USB 3.0 Hard Drive. Corsair Builder Series CXM 600W Modular 80 PLUS Bronze PSU.

Rated 5 out of 5 by from Silent fan This unit is really quiet and moves the air very well

Rated 5 out of 5 by from Absolutely fantastic I'd almost forgotten I'd put them in they're that quiet. I haven't even used the Low Noise Adapters.
