Just click on the Configuration button and then on the Advance tab. There are a couple ways you can boot your computer into BIOS. Simply downloading SpeedFan and hitting the UP arrow will not increase your PC fan speed. It should resolve the Speed fan not detecting fan problems. Change it from S3 to S1 and save the changes as a custom default. In BIOS under the Power tab, you will see the setting for ACPI suspend type. After that, you need to go into BIOS settings to bypass the CPU fans. Once you update, then check if SpeedFan supports your motherboard chip. In this situation make sure that you have installed the latest version of Speedfan and BIOS. Sometimes SpeedFan doesn’t detect fans, be it CPU or case fans. ![]()
