Noctua NF-F12 PWM, Premium Quiet Fan, 4-Pin (120mm, Brown)

Product Information

If you want to know more about Noctua fans, read our other blog posts that answer some of the most popular questions. Turn off automatic mode—If you notice that your fan runs slow and you want to change the speed, then turn it off. Switch off the automatic fan control on your BIOS. It will keep your fans running at full speed. On the con side, the software is somewhat dated and may not be compatible with all devices. How To Control Noctua Fan Speed With Voltage Adjustment It will give you a finer control level over the speed of your fans. You can reduce the power supply below twelve volts and consequently reduce the speed of the Noctua fans. It’s vital to understand that tinkering with the PSU can be harmful to not just the power supply but also to you.

This option is useful if (1) you don’t like to mess around in BIOS, (2) Noctua’s PWM function doesn’t work for your setup, and (3) You need extra customizations not available in BIOS. If you use a 3-pin version, you’ll need a workaround such as voltage adjustment (see how-to instructions later in this article). Enable the “CPU Smart FAN” profile and set it to whatever you want. It will keep your fan running at a slow speed as long as it’s within the specified voltage range. BIOS is a basic computer chip housed in your computer’s motherboard. It is an old and simple program that you can change based on your needs and preferences. How To Access BIOS Since the PWM signals control the motor using square waves of 25kHz, you can reduce them. These waves form a duty cycle that will regulate the fan’s speed. Lower the duty cycle to at least 40% of the total time period of the PWM signal.standard line: HS-PWM versions are the highest speeds in this line, PWM and FLX versions are high to moderate speeds and ULN versions are the lowest speeds

For Noctua fans with 4-pin connectors, you can also deactivate automatic fan speed control in your BIOS settings.

Performance and application-type considerations for 120mm fans (airflow vs static pressure): In the 120mm range, Noctua offers the NF-A12x25 that provides superior performance in all applications and models such as the NF-F12 and NF-S12A or NF-P12 redux and NF-S12B redux that are focused solutions for either airflow or pressure-demanding applications. See this guide for further explanations. Note that there is no distinction between airflow and pressure-focused models in all other sizes. Except for the NF-F12, NF-P12 and NF-S12 lines, all other Noctua fans are designed to provide optimal results in both types of applications. In particular, Noctua’s A-series models are universal solutions that are excellent both as case fans and on coolers and radiators. After that, you can slow your fan speed in real-time and set it to alert you when the temperature reaches a certain point. Although nicer fans still aren’t that expensive (relative to other PC components), you still get what you pay for. Ball bearings, often found in the least expensive fans, tend to fail more often, while sleeve bearings are a step up in quality and longevity, and fluid bearings tend to be the most reliable, with the longest lifespans. Unlike most PC components, fans are mechanical systems meant to run continuously for years, so get good ones! For example, all fans have a specified minimum threshold voltage rating. If it falls below the specified threshold, the fan stalls. How To Control Noctua Fan Speed With PWM

Popular choices and recommendations:Still undecided? Here’s a list of our most popular models of each size that have proven to work extremely well for the vast majority of users: However, these are generalizations. The ‘right’ fan speed for your particular Ender 3 Pro should be a matter of experimentation and dialing in until the print quality/strength lines up with your preferences/needs. Product line and colour scheme: In addition to the standard line of premium-quality quiet fans that is easily recognisable by the signature brown colour scheme, Noctua offers 3 dedicated product lines for specific demands: While first and foremost a duct upgrade, it’s also an entire system to upgrade almost every component attached to the print assembly.It may be easier to just sidestep the issue by going for a 24V Ender 3 fan upgrade from the get-go.

Some makers have reported solid results with a 40 x 10 mm fan like the ever-popular Noctua, but many report heat creep issues that can lead to clogging and filament extrusion. industrialPPC: Speeds are designated in the product name numerically, e.g. NF-F12 industrialPPC-2000 is 2000rpm, NF-F12 industrialPPC-3000 is 3000rpm.It is the only free software that allows you to set the speed for each fan individually. You will also be able to see the temperatures for all fans, speed, and the water temperature of your AIO cooler. Upgrading the Ender 3 part cooling fan requires a new fan alongside a 3D printed cooling duct/shroud. Ender 3 Cooling Fans The first three pins use almost the same signals as the 3-pin fan, but with one slight difference. Pin #2 has the same +12 VDC throughout and never reduces.
