Laptop fan noisy after update
4.5
The fans spin louder or more frequently after a recent OS or BIOS update.
Symptoms
- High pitch noise
- Constant fan
- Performance drop
Possible Causes
- New power profile
- Background indexing
- BIOS bug
Step-by-Step Fix
1
Wait for Indexing
After updates, the OS often re-indexes files, using high CPU for a few hours.
2
Check Power Mode
Ensure the laptop isn't stuck in "Best Performance" mode.
3
Rollback BIOS
If the fan curve is broken in the new version, revert to the previous one.
When to See a Technician
Manufacturers sometimes increase fan speeds in updates to prevent long-term heat damage.
