If your PC sounds like a jet engine, you’re not alone…

That loud whirring or buzzing noise coming from your desktop or laptop can be annoying — and concerning. Whether you're trying to focus, work, or game, a noisy computer is a red flag you shouldn't ignore.

Let’s break down what might be causing the noise and what you can do about it.

What Causes a Loud PC?

A loud PC typically means something inside is working harder than it should, often due to one of these common issues:

1. Dust Build-Up

Over time, fans collect dust — especially if your PC is on the floor. Dust clogs vents and makes your fans spin faster to cool down the system.

2. Failing Fans or Power Supply (PSU)

Older or worn-out fans, or a failing power supply unit, often make grinding or buzzing noises before they give out completely.

3. Overheating Components

If your CPU or GPU gets too hot, your PC compensates by cranking up the fan speed — which means more noise.

How to Check or Fix It Yourself

Want to try diagnosing the issue before calling for help? Here's what you can do:

Clean your PC with compressed air — especially around the vents and fans.
Install a free temp monitor like HWMonitor or Core Temp to check for overheating.
Check Task Manager to see if something is overloading your CPU/GPU.

⚠️ Reminder: Opening your PC voids may void warranties. Only do this if you're comfortable handling hardware.
