Computer fan is loud or running constantly
A loud fan is your computer cooling itself down. Something inside is making heat and the fan is spinning fast to handle it. Dust in the vents or a program running at full power is the usual cause. Clean the vents with compressed air and check what's running.
A loud fan means something inside your computer is working hard and making heat. The fan spins faster to cool it down. Dust clogging the vents, a program using all the CPU, or the room being too warm are the main reasons. We'll clear the dust and find what's eating your computer's power.
- ✓Have a can of compressed air ready — you'll use it to blow dust out of the vents
- ✓Keep your computer on a hard, flat surface like a desk — don't put it on a bed, couch, or carpet
- ✓Stay near your computer while you work through the steps so you can listen to how loud the fan is
Fix-IT-Bot will walk you through each step, just tap, no typing needed.
Skip, I just want a technicianCommon mistakes to avoid
- Sticking something into the vents to slow the fan down — this breaks the fan blades
- Ignoring a fan that sounds like a jet engine even when nothing is running — that's a sign something is wrong
- Thinking you need a new computer just because it's loud — cleaning the vents fixes it for people
Signs you need professional help
- If the fan makes grinding, screeching, or rattling sounds, or if your computer shuts down from overheating, get in touch. If cleaning the vents and restarting didn't help and the fan is still loud, give us a call and we'll check if it's a hardware problem.
