What type of CPU fan you can control?
The method to control the fan speed on a laptop and PC is highly dependent upon how your PC fans are powered.
You can control only those fans that are connected to your PC motherboard but if these are connected to the power supply then you can’t manually adjust their speed.
You can also check the end of the fan cable to know if you can control the fan speed on the PC.
- Molex fan connectors take power from the PSU. They cannot be manually controlled but can only be limited using a resistor cable.
- 3-pin DC fan connectors are connected to the motherboard, so you can alter its speed by limiting the voltage via BIOS.
- 4-pin PWM (pulse width modulation) can be controlled using fan control software easily.
Why is it important to monitor CPU fan speed in Windows?
The purpose behind the CPU fan is quite simple. They regularly check your PC’s temperature and adjust the CPU fans peed by turning them on and off accordingly. Every PC case has air vents to allow the heat to escape.
If you find your CPU fans to be running constantly, it’s a sign that your system is overheating and that may cause problems with your power supply. Thus, it can be very important to maintain a balance with the CPU fan speed while also keeping your PC’s temperature in check.
