Your computer fan is loud or won't stop running
A loud fan is your computer cooling itself — it's not broken. The fan spins fast because something inside is making heat and needs cooling. Check that your vents aren't blocked and clean any dust with compressed air.
A loud fan means something inside your computer is working hard and making heat. The fan is supposed to spin faster to cool it down. Dust in the vents or a program using full power is the usual cause. Clean the vents and it quiets down.

Skip — I just want a technicianCommon mistakes to avoid
- Sticking something into the vents trying to slow down the fan — this breaks the fan blade
- Ignoring a fan that sounds like a jet engine even when you're not doing anything — something is wrong
- Assuming you need a new computer just because it's loud — it can just need cleaning
Signs you need professional help
- If the fan makes loud grinding or screeching instead of a steady hum
- If your computer gets so hot it turns itself off without warning
- If the fan is loud even when you're not doing anything
- If cleaning the vents and restarting didn't help
