Why is my laptop’s fan running loudly even when it’s not performing any tasks after a system update?

1. Check to see if the fan is actually running by observing it for a few minutes.
2. Perform a full system scan if the fan is still running to check for any malicious software.
3. Ensure that the laptop is not overheating by blowing cool air close to the fan.
4. Update the device’s BIOS if any system updates were recently installed and investigatethe issue.
5. If none of these steps appear to stop the fan from running, then contact a hardwareexpert to analyze the issue.
