pin headers contain 2 connectors for current and grounding and a third connector that relays information to the user about the RPM of the fans for monitoring purposes. 3-pin connectors can have their RPM modulated by adjusting the voltage sent to the fan, although this method isn’t as precise as 4-pin controllers. 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) 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. A: Newer AMD cards are not supported. If you can provide a working sample of code that works with these newer cards, please share! You just hook it up to one of the motherboard’s 4-pin fan header and you now have a PWM fan control for up to three fans alongside manual control. The controller can also work with non-PWN fans but then it’s limited to manual control via the knob.

Hell yeah... Great write up. I'm sure there will be plenty more controllers built because of this; I, for one, am going to be putting my bread-boarded controller down on perf-board pretty soon. And once the first one is all done there will be a few more coming behind it. As you can see it's nowhere near the required frequency. You can run a fan with this signal but it will behave erratically. When the time comes to make a proper circuit using scary grown-up tools like a soldering iron and a pair of wire cutters, it is definitely worth your while planning the layout of your circuit once again and trying to make it as compact as you can. If you have space on your stripboard you might want to consider soldering a 4-pin fan header onto it to keep the controller tidy and practical.

Overview

SpeedFan is one of the oldest tools out there. Its history is almost as old as Windows itself. The first version was released around the time Windows 9x was considered the cutting edge in operating systems. It’s that old. Timer 0 (Pins 5,6) is identical to Timer 2, so we could apply the same settings that we used for it and get an extra output for a fourth fan; however, it is used for all timing functions such as delay, millis, etc. and touching it would cause everything that depends on this to behave erratically, including our Serial output. My code doesn't touch this timer. Fortunately, these circuits were never mainstream. Appliances such as air conditioners and refrigerators just ran at full speed all the time, making lots of noise, and wasting lots of energy because they had to cycle on and off frequently. 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. For those who want the maximum control over their computer’s cooling system, there’s no substitute for a fan controller. Adjust the speed of any of your fans with the press of a button. Of course, they also add the final visual touch to a highly customized PC, with LED panels and sleek, advanced design considerations.

Since the application is ASUS-specific, you can only control the fan speed of the ASUS graphic card. ASUS AI Suite 3 uses Fan Xpert 4 to manage all the fans connected to your motherboard. This also includes all case fans that are connected to the motherboard. But, you should have an ASUS motherboard to access this feature. MSI Dragon Center (For Windows) You can also set the speeds of your fans to correlate with your CPU’s temperature. Just keep in mind that you don’t want to set a threshold that is too high, as doing so could prevent your CPU from getting the airflow it needs to operature correctly. pin fan controllers have a fourth connector pin that lets them modify fan speed on a software level. This is called “pulse width modulation” (PWM) and works by controlling the amount of current given to the fan at any given time. For example, a 4-pin connector might only give electricity to the fan in short bursts at a time to save on energy.The Kingwin FPX-007 fan controller is a 5.25-inch drive bay mounted device. It's simple to connect to your motherboard and provides a clear and easy-to-read LCD display, allowing you to control the fans in your PC case. You can easily switch between Celsius and Fahrenheit by pressing and holding the temperature switch. Razer tends to have everything related to gaming and PC building so it is not weird that they also produce a fan controller. Is this fan controller somehow better than the rest? Not really, but it does come with a certain advantage too.
