Noctua NA-FC1, 4-Pin PWM Fan Controller (Black)

Product Information

To fix a CPU fan error, move your computer somewhere cooler to reduce the effects of overheating. Clean its air vents of any dust and debris, and clean the CPU fan. If you installed the CPU fan yourself, ensure it's in the correct location. You may need to replace a faulty CPU fan.

If you want to vary the speed of DC fans, the only option is to vary the input DC supply. The DC power supply can be reduced below 12 V for lower speeds. There are still limitations in the percentage decrease in the speed of DC fans. All the DC fans are specified with a minimum threshold voltage rating; if the voltage falls below the threshold, the fan starts to stall. For continuous spinning motion, this minimum voltage needs to be supplied. https://github.com/hgross/FanControl.HomeAssistant to interface with HomeAssistant connected temperature sensors (i.e. ambient temperatures via Philips Hue, HomeMatic, HomeKit or many other brands & protocols) DC fans are supplied with DC power from regulated DC supply or motherboard header pins. These fans are also called 3-pin fans, as they come with 3 pins: a supply pin (usually 12 V DC), a ground pin, and a signal pin. It also has a temperature alarm that notifies you when temperatures go beyond safe levels. It even stores fan and calendar settings when the controller is off. The main downside is that it only supports 3-pin connectors.

Step 1: Organize Your Components and Print a Plan of the Circuit These are all of the components you need for the circuit The Corsair iCUE Commander PRO powers up to six case fans and has the ability to run at zero RPM, achieving total silence. There are two RGB lighting channels that leverages iCUE software to allow you to fully customize your PC case, including RGB LED strips and RGB fans. Electronic product cost estimation recognizes that balance must exist between costs, risks, and benefits. When the app fail to start due to sensor initialization issue, the sensor settings window will open This is the release repository for Fan Control, a focused and highly customizable fan controlling software for Windows.

Note that the official spec says that the minimum duty cycle for the fans should be 20%. Decent fans like the Noctua ones I used in my tests can take any duty cycle, but you should keep it in mind if you're using cheaper fans. RPM detection Sync with your motherboard using the included Motherboard Cable instead of the Manual Remote. The Universal Fan Controller can read any DC or PWM signal from the motherboard and will automatically control all connected fans accordingly. Whether you want to build your own home theater or just learn more about TVs, displays, projectors, and more, we've got you covered.The SilverStone PWM Fan Hub is a compact solution to cooling your entire PC at once. Featuring reliable speed-detection sensors, this PC fan controller boasts PWM support for cooling your system on autiopilot. There's a built-in 2200μF capacitor to maintain stable voltage across your PC, keeping it safe from overheating regardless of the task at hand. Need a program to help you gain more control over the fans in your computer? In this post, we’ve highlighted four fan control programs to help you find the right option for your needs. I’ve been using Argus Monitor over a year and it’s fantastic. You can select multiple control temps. Anything your motherboard reports, included drives and memory modules. I believe you can use it for free, although some features are not available. Otherwise it’s 10 euros for a 1 year license which will give you lifetime access to all features and any updates within your license period. This controller can fit up to six fans, as well as two RGB channels, four temperature inputs, and even a couple internal USB devices. When it comes to connectivity, this fan controller is the king. Besides building desktop PCs, Deep also has hands-on experience fixing software and hardware issues on laptops and desktop computers. Using all this knowledge and skills about computer hardware, he's on a quest to make content that's easy to read and understand for everyone.

Think of a PWM signal as if it were a beating heart. Rather than being powered by a continuous supply of power (which would ordinarily be the case) our DC fan motor is being fed with pulses of power; it is essentially being switched on and off very rapidly. These on-off pulses are delivered to the motor several thousand times per second, and because the intensity (or width) of each pulse can be changed, so the speed at which the motor turns can be changed. The image below shows how different pulse widths affect the resulting power of the PWM signal: Three different PWM signals showing average voltage PWM Controllers vs. PWM Fans The Corsair iCUE Commander CORE XT can turn any case into a smart PC case by using the software that it comes with to adjust all of your fan speeds and RGB. This means that you can connect up to 6 case fans and control them from Windows without ever opening your BIOS.

The software is completely free to use but the developer (Rem0o on GitHub) does accept donations. And, considering that Rem0o was able to create a truly all-in-one fan control program where many other professional developers have come up short, it wouldn’t hurt to throw a donation their way. You can plug in up to 10 PWM fans (4 pins) and control them all using one single fan curve through your motherboard BIOS. Since this is a simple hub the fan speed you set up will be applied to all of the fans connected to this hub and will be seen as a single fan connected to your motherboard in your BIOS (this is how hubs work generally). I’m sure that most hardware enthusiasts are no strangers to dalliances with DIY, whether it be case modding, component modding, or custom cooling. However, when it comes to building parts of your computer from scratch, the tally of enthusiasts who can claim this prestige most certainly diminishes. Fortunately, this neat fan controller project requires only a little time, expense, and commitment, and the circuit is relatively easy to build and very satisfying to use! First Things First…What is PWM?

Connect up to 8x fans or more* to the Universal Fan Controller. Both 3-pin(DC) and 4-pin(PWM) fans can be controlled simultaneously. Note: A fan curve is a chart visualization of fan speed and temperature. Using the chart, you can set the fan speed according to the temperature. Follow these steps to create your own fan curve. Corsair iCUE allows you to synchronize the RGB lighting on all of your compatible corsair devices. There are four waves of light to choose from: Rainbow, Yellow, Rain, and Visor. The best way to read this is to use one of the Arduino pins that can do interrupts (2 and 3 on the Arduino Uno). I will use pin 2 in this example: #define PIN_SENSE 2 //where we connected the fan sense pin. Must be an interrupt capable pin (2 or 3 on Arduino Uno) Argus Monitor can also help you identify if there are early warning signs that your hard drive or SSD is failing. The program warns you (with 70 percent accuracy) that your drive is failing. This gives you ample time to get a new one and transfer all your important files from the old drive.

Note: SMART (Self-Monitoring, Analysis, and Reporting Technology) is a hard disk monitoring system that provides information on a drive’s status. The Noctua NA-FC1 is a tiny fan controller that comes with a single fan header. The controller can control up to three fans thanks to the three-way splitter that comes with it. The controller supports both automatic PWM and manual control via a tiny knob. PWM works by pulsating DC current, and varying the amount of time that each pulse stays ‘on’ to control the amount of current that flows to a device such as an LED. PWM is digital, which means that it has two states: on and off (which correspond to 1 and 0 in the binary context, which will become more relevant to you if using microcontrollers). HWMonitor is another program that has been around for quite a while. And during that time, it has distinguished itself and cultivated a userbase that keeps growing. HWMonitor does everything the other programs do and then some.
