How To Control CPU Fan Speed on Laptop and PC Windows 10/11

Manually change the CPU fan speed at 100% RPM on the laptop or PC to avoid overheating problems.

Looking for laptop fan control or fan speed control for Windows 10 because you want to change or control the fan speed on a laptop or desktop PC? In this article, you will learn easy solutions on how to increase the fan speed on a PC.

Every PC and laptop has built-in fans that blow off the heat generated when a process is running through. While running multiple applications on Windows OS or tabs on Chrome you might feel hot air coming out of your system.

It doesn’t matter if it’s a high-end gaming rig or gaming laptop you will hear a CPU fan noise when you boot up your PC and sooner the startup process completes the noise goes on to decline.

The problem only starts when you constantly hear CPU fan noise or nothing at all when running tasks.

What type of CPU fan you can control on a PC?

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 see if you can control the fan speed on the PC.

  • 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 fan’s speed 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.

Locate the Hardware Monitoring screen or Advanced Tab then find PC Health Status. Here you will find

In the BIOS typically you can adjust the optimal CPU temperature range at which the fan will speed up, and often the speed itself.

Methods 3. Control CPU fan speed using SpeedFan [Fan controller software]

Among other best fan control software, the SpeedFan is the most popular and easy-to-use tool. It searches your computer for informative chips and puts up voltages, speeds, and temperatures on display. SpeedFan uses S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) sensors that run through your motherboard and video cards to extract accurate relevant data.

Here’s how you can use it.

Step 1: Download SpeedFan and once it is downloaded, double-click the file and follow the installation steps.

Step 2: Open SpeedFan and you’ll find it in your Windows Start menu. You might need to grant it permission to access your PC’s settings.

Step 3: Check Compatibility after a moment, you’ll see information about your PC. If you don’t see any fans or they show “0 RPM,” your motherboard isn’t supported by SpeedFan.

Step 4: Configure Fan Speed by clicking the “Configure” button in the upper-right, and then the “Advanced” tab at the top.

Click the Configure button. It's in the upper-right area of the window.

Step 5: Select Choose your CPU from the “Chip” menu. It’s usually something like “IT” ending with “ISA.” Look for entries with “PWM (a number) mode” in the Properties box. If you can’t find your CPU or any options with “PWM mode,” you can’t change fan speed.

Select your CPU from the Chip menu of SpeedFan

Step 6: Now set the PWM Modes that let you change each PWM mode to “Software controlled.” To do this, click on each PWM mode entry and select “Software controlled” from the dropdown menu at the bottom. Avoid “Smart Guardian” as it’s for automatic control.

Step 7: Save Changes by clicking “OK” to return to the main SpeedFan screen.

Step 8: To identify PWM controls look at each fan speed on the left and the corresponding PWMs with percentage values below. Here’s how to identify which PWM controls which fan:

Find which PWM controls each component's fan
  • Write down the percentage of the first PWM setting.
  • Set the first PWM to 0% temporarily, and observe which temperature starts rising. This temperature is affected by that PWM. Write it down.
  • Return the original percentage to the box.
  • Repeat for other PWMs until you know which controls which fan and what the default values are.

Step 9: Adjust Fan Speed: Raise or lower the percentage for each PWM. Start with small adjustments, like changing by 1 or 2 percent. Keep an eye on temperatures to avoid overheating and monitor how it affects performance.

This PC fan control software also lets you check accurate CPU temperature readings. You can also see your current fan RPM. You can manually control and increase the fan speed on a laptop with these tools.

Note: Speedfan supports a wide variety of computer motherboards and sensor chips. If this laptop fan control software lacks support then you can download Argus monitor or MSI Afterburner.

Another disadvantage of this fan speed control for Windows 10 is that it onlyΒ supports built-in CPU and Case fans.

If SpeedFan not detecting fans then you might have additional PC fans in your system. This fan control software doesn’t control them.

If PC fan controller software doesn’t let you control, change, or increase the fan speed on a laptop PC then don’t worry you have a plan B.
