Do you want to prevent overheating in PC while gaming or working? Is your laptop getting hot or slowing down unexpectedly? These issues are often caused by overheating — a critical problem that can damage your CPU, GPU, and other components.

At A2z Computech, we see this problem frequently, especially in older systems or those used for gaming and editing. If not addressed early, it can lead to expensive hardware damage or even permanent failure.

In this guide, we’ll explore the causes of overheating, how to fix it, and steps you can take to prevent overheating in PC for good.

Why Is Your PC Overheating?

Common causes include:

• Dust buildup inside the fans and vents
• Blocked airflow due to poor PC or laptop placement
• Old thermal paste not conducting heat efficiently
• Faulty or weak cooling fans
• Heavy usage like gaming, rendering, or multitasking
• Using laptops on beds, cushions, or soft surfaces

Signs Your PC or Laptop Is Overheating

Not sure if your system is overheating? Look for these signs:

• Constant loud fan noise
• Device feels hot to the touch
• Sudden slowdowns or freezing
• Unexpected restarts or shutdowns
• Games crash or show visual glitches
• Hot air blowing from vents for long periods

How to Fix PC Overheating: 6 Expert Tips

1. Clean Dust from Inside the PC or Laptop

Dust is the biggest enemy of your PC’s airflow.

• Use a can of compressed air
• Focus on CPU, GPU, and PSU fans
• Clean every 2–3 months for best results

2. Improve Airflow and Placement

• Use your laptop on a flat, hard surface
• Avoid blocking vents against walls or fabric
• Use a laptop cooling pad
• Add extra case fans if using a desktop

3. Replace Old Thermal Paste

Over time, thermal paste dries out and stops transferring heat properly.

• Reapply every 1–2 years
• A2z Computech can safely replace it for you

4. Upgrade Your Cooling System

Gaming and editing rigs need stronger cooling.

• Upgrade to a premium air cooler or AIO liquid cooler
• Add intake and exhaust fans for balanced airflow

5. Use Software to Monitor Temperature

Install tools to track CPU and GPU temps:

• HWMonitor
• Core Temp
• MSI Afterburner

Keep temperatures under 85°C during heavy use. Over 90°C is dangerous and may cause thermal throttling.

6. Close Unused Background Programs

Free up system resources and reduce heat output:

• Press Ctrl + Shift + Esc to open Task Manager
• End unnecessary processes
• Disable startup apps to improve boot time and reduce background load
