Keeping your gaming PC cool, clean and fast

A gaming PC works hard and makes heat. Dust and clutter make that heat harder to get rid of. A little care now and then keeps it cool, quiet and fast for years. Here is what to do, in plain steps.

Why heat matters

When parts get too warm, they slow themselves down to stay safe. Games can stutter, and fans get loud. Keeping the PC cool helps it run at full speed and helps the parts last longer.

Give it room to breathe

• Do not block the vents. Leave space around the back, the sides and the top.
• Keep it off carpet. Carpet blocks vents underneath and feeds in fluff.
• Keep it out of closed cupboards, and away from radiators and strong sun.

Deal with dust

Dust is the main enemy. It clogs fans and filters and traps heat inside.

Dust filters. Many cases have filters, often at the front, the top or underneath. Many slide or clip out without opening the case. Check them every month or two, and rinse or brush them clean. Let them dry fully before putting them back.

Inside the case. Before you do anything:

1. Switch the PC off and unplug it from the wall. Never touch inside a PC while it is plugged in.
2. If it is still under warranty, check with the seller first before opening the case.
3. Take it outside, or near an open window, so the dust does not settle back in your room.
4. Use short bursts of compressed air on the fans, filters and vents. Hold each fan still with a finger so it does not spin too fast.
5. Do not use a vacuum cleaner inside, and do not use water or sprays.

If you are not happy doing this yourself, that is fine. A repair shop can do it for you.

Keep cables tidy

Cables inside a case can block the air. Most gaming PCs are built with cables tucked out of the way. If you add anything, keep its cables tidy too. Behind the desk, keep cables loose and away from the vents.

Keep the software healthy

A clean PC is not just about dust. The software matters too.

• Run Windows Update regularly. It fixes problems and keeps the PC safe.
• Update your graphics driver through NVIDIA or AMD's own app. New drivers often help new games run better.
• Uninstall programs you do not use. Go to Settings, then Apps. Fewer programs starting with Windows means a faster start.
• Remove games you have finished with. Big games fill up storage. A very full drive can slow things down.

Keep an eye on temperatures

You do not need to watch temperatures all the time. But if a game stutters or the fans roar, it is worth a look. The graphics card's own app can often show its temperature. If it seems much hotter than it used to be, clean the dust first. If that does not help, ask for advice.

Signs it needs help

• Fans are much louder than they used to be.
• The PC switches itself off or restarts during games.
• Games stutter more than they did when it was new.
• The case feels very hot, or there is a burning smell. Switch off and unplug straight away.
• Strange noises such as grinding or clicking.
