Award-winning NF-F12 design

Award-winning NF-F12 design

Having received more than 150 awards and recommendations from the international press, Noctua's NF-F12 has become a proven premium choice for 120mm cooling needs. Its renowned efficiency has convinced tens of thousands of customers all over the world.
3000rpm industrialPPC version

3000rpm industrialPPC version

Running twice as fast as the 1500rpm retail version, the NF-F12 industrialPPC-3000 PWM provides extreme airflow and pressure performance. Combined with the industrialPPC series' robust polyamide construction and advanced protection features, this makes the fan ideal for challenging industrial applications.
Three-phase motor design

Three-phase motor design

While most axial fans use single-phase motors with 4 slots, Noctua's industrialPPC fans feature a three-phase design with 6 slots, which provides smoother transitions between the slots and thus allows for even higher running smoothness, further reduced vibrations and unprecedented energy efficiency.
Class-leading energy efficiency

Class-leading energy efficiency

While the standard NF-F12 is one of the most energy efficient 1500rpm 120mm fans on the market, the industrialPPC version's three-phase motor provides a further 10% reduction in power consumption when compared at 2000rpm.
Fibre-glass reinforced polyamide construction

Fibre-glass reinforced polyamide construction

Both the impeller and the frame of Noctua’s industrialPPC fans are made entirely from fibre-glass reinforced polyamide. This material can withstand temperatures up to 140°C and makes the fans even more robust and break-proof than Noctua’s standard fibre-glass reinforced PBT fans.
Certified IP52 water- and dust protection

Certified IP52 water- and dust protection

Thanks to a special varnish coating that covers the motor and PCB, the NF-F12 industrialPPC complies with the ingress protection rating IP52. This means that it is not only highly dust resistant but also withstands dripping water equivalent to 3mm rainfall per minute.
Focused Flow™ Frame

Focused Flow™ Frame

Designed for pressure demanding applications such as heatsinks and radiators, the Focused Flow™ frame features eleven stator guide vanes that straighten, channel and focus the airflow, which allows the NF-F12 to rival the performance of conventional fans running at much faster speeds.
Varying Angular Distance and Vortex Control Notches

Varying Angular Distance and Vortex Control Notches

The NF-F12's stator guide vanes are set out in Varying Angular Distance and feature Vortex-Control Notches. Both measures help to spread the noise emission over a broader frequency spectrum and thus make the fan's sound pattern more agreeable to the human ear.
Heptaperf™ Impeller

Heptaperf™ Impeller

Custom designed for the new Focused Flow™ frame and to work in tandem with the eleven stator guide vanes, the NF-F12's seven blade Heptaperf™ impeller has been carefully optimised to achieve a perfect balance between power and quietness.
Stepped Inlet Design

Stepped Inlet Design

Noctua's Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space-restricted environments.
SSO2 Bearing

SSO2 Bearing

The NF-F12 industrialPPC 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.
Metal bearing shell

NF-F12 industrialPPC-3000 PWM Review

The Noctua Redux and IndustrialPPC ranges add a much needed customisation to their range. Of course, the Redux fans are of an older design, and the performance may suffer as a result. However, the greys of the Redux and the black of the IndustrialPPC range enables system builders to more thoroughly theme their build and thus the sacrifice in performance or price may be considered worth it. The IndustrialPPC range also adds a ruggedness that some systems will require – water and dust resistance will enable significantly longer lifetimes with a higher MTBF.
Test verdict: "The usual Noctua product quality is still to be found here, and these fans are well worth considering for your system. Though the IndustrialPPC (and, let’s face it, the standard Noctua product line) remain quite expensive for the functionality they provide, the Redux line brings excellent acoustics and performance to more accessible price points. And as for the IndustrialPPC fans, we get the feeling that many enthusiasts will happily look over the price point in the quest for the best." (John Morrison, SmallFormFactor.net)

NF-F12 industrialPPC-3000 PWM Review

Jumping right into it and there is no denying the performance the industrialPPC range has to offer. Not only did they out-perform the fans I tested them against, they have a lot of other features that will allow them to perform better than your average fans. For one, the IP67 rating not only means they are water and dust proof, this also adds longevity to the fans as nothing will be getting in the motor and essentially slowing it down over time. Not only did they knock a good few degrees of my CPU temps during the test, they were also noticeably quiter than the fans they were tested against. When I say noticeably, I do in fact mean that, I could actually hear that they were a lot quieter than the other fans on test at the time.
Test verdict: "The industrialPPC fans offer great performance and design in a package designed for some serious cooling power, all in all a very worthy buy if you can make use of things like the IP67 rating." (Ben Enos, EnosTech.com)

NF-F12 industrialPPC-3000 PWM Review

Kaip matome, paspartintas procesorius išties įkaito nemažai. Be to šiuo metu Lietuvoje karščiai, todėl kambario temperatūra siekė 30 laipsnių. Ramybės būsenoje visi ventiliatoriai rodė apylygius rodmenis išskyrus NF-A14 IndustrialPPC 3000 PWM. Dėl savo dydžio ir didelio sukimosi greičio, jis nuo savo brolių pabėgo į priekį rodydamas keliais laipsniais mažesnę temperatūrą. Apkrovos metu matome, kad vėl gi NF-A14 IndustrialPPC 3000 PWM pabėgo į priekį aplenkdamas NF-SB12B Redux 1200 PWM ventiliatorių net gi 8 laipsnių skirtumu. Taip atsitiko dėl to, kad NF-SB12B Redux 1200 PWM iš visų ventiliatorių turėjo mažiausia maksimalų apsisukimų skaičių, na ir žinoma dydis irgi įtakojo rezultatus. Nors ir NF-A14 IndustrialPPC 3000 PWM parodė geriausią rezultatą, jis skleidė itin didelį triukšmą,kas nėra gerai. Triukšmas toks įkirus, kad po kurio laiko nebesinori naudotis kompiuteriu ir kuo greičiau dingti nuo ventiliatoriaus triukšmo.
Test verdict: "Noctua žengė protingą žigsnį pristatydama pigesnius ir geriau atrodančius Redux serijos ventiliatorius. Nors jie ir neparodė ir neaplenkė IndustrialPPC serijos ventiliatorių, tačiau dėl mažesnio triukšmo tai geras pasirinkimas. Kalbant apie IndustrialPPC seriją, taip tai puikų rezultatą generuojantys ventiliatoriai, tačiau dėl aukštų apsukų jie garsiai dirba, todėl siūlytume juos tik vartotojams triukšmas nėra faktorius."

Information Sheet (PDF)

Can industrialPPC fans be used with fan controllers and resistor cables (Low-Noise Adaptors)?

Noctua recommends not to use industrialPPC fans with common PC fan controllers, resistor cables (Low-Noise Adaptors) or other devices such as potentiometers that work by applying (variable) resistance rather than actually generating different voltages such as a laboratory power supply does. Due to the higher internal resistance of the industrialPPC fans’ three phase motor, applying additional resistance will cause the fans not to start (e.g. with Low-Noise Adaptors) or to have high starting speeds (e.g. with most common PC fan controllers). Please note that the industrialPPC fans feature starting voltages between 5.5V and 6V and can be run at these voltages on devices such as laboratory power supplies or mainboard fan controllers which actually generate lower voltages rather than applying resistance. Noctua thus recommends to use either PWM or voltage based mainboard fan control or laboratory/industrial power supplies for controlling the speed of industrialPPC fans.

Laboratory/industrial power supplies yes yes

My Noctua PWM fan starts to spin when the PC boots but then stops, what is wrong?

Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). In this case, it may occur that the mainboard reduces the voltage so much that the fan stops. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:

4 pin fan header types

Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.

Unfortunately, the description of Pin 2 is not always a clear indication as some manufacturers use terms such as “Fan PWR” or “Power” for both types of fan headers. However, if Pin 2 is described as “Speed Control”, you can also be sure that the fan header does not support PWM based speed control. If Pin 2 is described as “+12V”, this is a clear indication that the fan header supports PWM.

Please also note that in some cases, the descriptions of the pin layouts in the mainboard manuals may not be correct and some models actually allow you to switch the fan headers from voltage control mode to PWM control mode in the BIOS even though the pin descriptions do not indicate PWM support. We thus recommend to look for these options in the BIOS before taking other measures. In case of doubt, please contact your mainboard manufacturer.



To resolve the issue, you can:

  1. Choose a higher fan speed profile in the BIOS (e.g. „normal“ instead of „silent“, etc.) or deactivate automatic fan speed control and use a Low-Noise Adaptor instead.

  2. Use the mainboard‘s fan speed control software or 3rd party tools like Speedfan to regulate the fan speed. Unlike BIOS based fan speed control, the supplied software usually checks whether the fan has stopped and increases voltage accordingly or at least offer more options to set up the fan properly.

  3. If your mainboard features other 4-pin fan headers that use PWM for speed control, you can run multiple fans from these headers using Y-split cables. Make sure not to exceed the specified maximum power draw of the fan headers (usually 10-12W) though.

My Noctua PWM fan runs at a much higher minimum speed than advertised, what is wrong?

The specified minimum speed refers to the speed at 20% PWM duty cycle. There can be several reasons why the fan doesn‘t go as low as indicated:

  1. Many mainboards do not go below 40%, 50% or even 60% PWM duty cycle on case fan headers. Please refer to your mainboard manual to verify whether the fan header actually goes down to 20% duty cycle. If that's not the case, in some cases you can use the fan speed control software supplied with your mainboard to overcome these limitations and reduce the fan speed even further. However, 3rd party tools like SpeedFan offer greater flexibility and better options to work around the limitations imposed by the mainboard vendors.

  2. Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). As the fan speed at minimum voltage is usually higher than the speed at 20% PWM duty cycle, the fan can not reach as low minimum speeds under voltage control as under PWM control. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:

    4 pin fan header types

    Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.

    Unfortunately, the description of Pin 2 is not always a clear indication as some manufacturers use terms such as “Fan PWR” or “Power” for both types of fan headers.

    If your mainboard features other 4-pin fan headers that use PWM for speed control, you can run multiple fans from these headers using Y-split cables. Make sure not to exceed the specified maximum power draw of the fan headers (usually 10-12W) though.

I'm experiencing fan speed issues with my motherboard from Supermicro, what can I do?

The BIOS of many motherboard models from Supermicro expects a certain minimum fan speed (usually 700rpm), which is higher than the minimum fan speed that can be achieved with Noctua's PWM fan models. The BIOS may interpret the low minimum RPM of Noctua fans as a fan error and thus try to run the fan at 100% for a short period before going back to automatic control.. This can result in oscillating fan speeds and fan speed warnings in the BIOS or the fan management console.

Unfortunately there is usually no option to set a lower minimum value that would suit the low minimum speed of Noctua PWM fans.The issue can thus only be resolved by either disabling automatic fan speed control in BIOS, which will cause the fans to run at a constant speed, or by requesting a modified BIOS file from Supermicro, which takes the minimum fan speed of Noctua fans into account (charges might apply).

Can I use Low-Noise Adaptors for industrialPPC fans?

No, Low-Noise Adaptors are not compatible with Noctua’s industrialPPC series.

Can I run 4-pin PWM fans on 3-pin fan headers?

PWM fans come with a 4-pin connectors for fully automatic speed control via your mainboard’s 4-pin PWM fan headers. Please note that 4-pin fans can also be connected to your mainboard’s 3-pin fan headers though. When connected to 3-pin fan headers, the fan will run at full speed (unless the mainboard supports voltage based speed control).

How can I check if my 4-pin fan header supports PWM?

Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). As the fan speed at minimum voltage is usually higher than the speed at 20% PWM duty cycle, the fan can not reach as low minimum speeds under voltage control as under PWM control. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:
