Why Your Computer Fans Are So Loud (And How to Fix It)

If your computer sounds like a jet engine taking off, you're not alone. At SnapFix Repairs, we get calls about noisy PCs almost daily. The good news? Most fan noise is fixable.

Common Causes of Loud Fans

Dust buildup is the main culprit. When dust clogs your fans and vents, your computer works harder to stay cool, ramping up fan speeds. Other causes include failing fans, thermal paste that needs replacing, or simply running demanding software.

Quick Fixes You Can Try

First, shut down and unplug your PC. Use compressed air to blow out dust from vents and fans. Check if any cables are touching fan blades. For laptops, ensure vents aren't blocked by surfaces or debris.

When to Call a Professional

If cleaning doesn't help, or if you hear grinding or clicking sounds, it's time for professional help. At SnapFix Repairs, our PC maintenance service includes thorough dust removal, fan cleaning, and thermal paste replacement from £20.
