How to Raise CPU Fan Speeds on a Lenovo Laptop

If your business requires you to do a lot of work from your Lenovo laptop, you've probably noticed an occasional issue with overheating. Running several intensive programs on your laptop can raise the CPU temperature, causing the cooling fans to engage. You may need to raise the speed of the fans from time to time to rapidly cool the CPU and prevent a sudden shutdown. You can boost CPU fan speed from your laptop's BIOS menu.

1. Install the latest BIOS update on your laptop if necessary. This update can be downloaded free from the Lenovo Support page (link in Resources).
2. Turn off your computer after you've installed the update. Turn the computer back on. When the boot screen appears, press and hold the "Delete" key to load the BIOS settings menu.
3. Press the directional arrows on your keyboard to select "System Monitor." Press "Enter." Select "Fan Control" and then select "CPU Fan Speed Control."
4. Switch the control from "Automatic" to "Manual." This allows you to manually control the CPU fan speed by percentage.
5. Enter the desired percentage at which the fan should run. To run at full speed, enter "100" for 100 percent. You should only run fans at full speed for long enough to effectively cool the CPU.
6. Press the "F10" key to reboot the computer and raise the speed of your CPU cooling fans. To return the fan speed to normal, repeat the above procedure but switch the fan control back to the "Automatic" setting.
