Using the Dragon Center, you can customize any MSI product connected to your motherboard. This includes monitoring all the stats (CPU/GPU temperature, frequency, voltage, etc.) and fan control. You can choose three settings to control your fan speed: Auto, Manual, and Advanced. Auto is the default setting. Manual settings allow you to set the speed (in%) according to your need. The fan will spin at the set speed regardless of the graphics card’s temperature. Selecting the Advanced settings, you can set the fan curve according to your need. The squares in the PWM illustration below are the pulses which represent ‘on’ time, and the depressed areas represent the time that the power is ‘off’. Both the squares and depressed areas are the same ‘width’, therefore the duty cycle is 50%. PWM signals are typically square waves, like the one in the illustration below. A PWM signal (square wave) with a 50% duty cycle.

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) With EasyTune 5, you get more than just a tool to monitor and control your fans’ speeds. The program also has a bunch of other useful features at your disposal that you probably didn’t know you needed. The exact specs of these fans were made by Intel in the mid-00s and are available here: Original | Latest version | Noctua Connecting the fan to the Arduino 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 A good fan control application makes it easier to tune the CPU and GPU fans for maximum performance with minimum noise. Keeping this in mind, we have listed some of the best fan control software that you can use. MSI Afterburner (For Windows)

PWM control

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. As you can see it's nowhere near the required frequency. You can run a fan with this signal but it will behave erratically. 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.

Pulse width modulation has changed the world by slashing the power consumption of appliances utilizing motors such as inverter air conditioners [ PDF], inverter refrigerators, inverter washing machines, among many others. For example, inverter air conditioners can consume less than half the energy that their non-inverter counterparts do in some cases.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. attachInterrupt(digitalPinToInterrupt(PIN_SENSE),tachISR,FALLING); //set tachISR to be triggered when the signal on the sense pin goes low This german software can control every case fan connected to the motherboard. You can also make your own fan curve configuration. Like SpeedFan, it uses SMART sensors to display HDD/SSD temperatures. Including all this, it also displays real-time CPU/GPU temperature.

The same efficiency rule that applies to resistors also applies to transistors— Their resistance results in wasted energy because they burn off some of it as heat. They act like heaters in that regard. https://github.com/EvanMulawski/FanControl.CorsairLink to interface with Corsair Commander controllers and Hydro liquid coolers 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.Note: SMART (Self-Monitoring, Analysis, and Reporting Technology) is a hard disk monitoring system that provides information on a drive’s status. The PWM signals on the Arduino Uno (and others based on the ATmega328p, such as the Nano) are generated by 3 internal timers. With the default settings and using analogWrite with a value of 127, this is what we see on an oscilloscope: If the duty cycle of a PWM power supply is set to 70%, then the pulse is on for 70% of the time, and it is off 30% of the time. Duty cycle refers the amount of time it is on. At a 70% duty cycle, an LED’s brightness should be near 70%. The correlation between duty cycle and brightness is not 100% linear, as the efficiency of LEDs varies with the amount of current supplied. https://github.com/brokenmass/Fancontrol.NzxtKraken to interface with NZXT Kraken AIO that are not yet supported by LibreHardwareMonitor for example Kraken X2 and Kraken X3 - new PID.

The additional heat generated by traditional transistor circuits is another consideration, as it may increase the amount of time that cooling fans have to stay on to reduce the temperature of said devices. PWM Signal Having a long history is usually a good thing. Especially for a customizable program with a clean user interface that is compatible with all versions of Windows. However, SpeedFan hasn’t been updated since 2015 and so it isn’t the best option for newer systems. The Phanteks Universal Fan Controller is an interesting device. It comes with five four-pin fan headers for PWM fans but also includes three 3-pin headers for non-PWM fans that can receive PWM control when hooked to the controller. You can control even more fans if you use fan headers.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 one downside of HWMonitor, though, is that the user interface is a bit clunky. It might take you a while to get familiar with the columns of numbers in front of you. But once you know your way around, you’ll never want to use another application. https://github.com/EightB1ts/FanControl.LianLi to interface with LianLi L-Connect 3 fan controllers
