An outdated BIOS or firmware can cause your PC fan to speed up unnecessarily. This is because the old software may not be optimized for your PC’s hardware, leading to inefficient cooling.
Hardware Issues
Hardware issues like a failing hard drive or a malfunctioning GPU can also cause your PC fan to speed up. This is because the system is trying to compensate for the failing hardware by increasing fan speed.
Diagnostics: Identifying The Culprit
Now that we’ve covered the possible reasons behind your PC fan’s speed increase, it’s time to diagnose the issue.
Monitoring System Temperatures
Use software like SpeedFan, HWiNFO, or GPU-Z to monitor your system temperatures. This will help you identify which component is overheating and causing the fan to speed up.
Checking For Dust And Debris
Inspect your PC’s air vents, fans, and heat sinks for dust and debris. Clean out any blockages using compressed air or a soft brush.
Reviewing System Logs
Check your system logs for any errors or warnings related to overheating components or hardware issues.
