Clean your PC

If you haven’t dusted or cleaned your computer in a while, grime is most likely to blame for your computer heating up. Dust tends to block key parts of the computer that air should normally circulate through, and this can lead to overheating.

Thankfully, a desktop computer is pretty easy to clean, even though most laptop owners might choose to get their devices serviced at a repair facility. However, the steps we’ve listed below should help you clean your computer just fine if you wish to do so on your own:

  • Turn off the PC entirely and unplug it first.
  • Next, open the lid, you ought to be able to see dust. You can use a leaf blower or a can of compressed air to clean it up (at slow speed). Blow air into the primary computer parts, paying specific attention to the fans, from the front and back.
  • To clean the confined spaces, you can also use cotton buds. The goal is to remove any blockage brought on by dust, so don’t panic if you can’t get it sparkling clean.

Once you get rid of the dust and grime, ventilation should be restored, and the overheating issue will reduce considerably.

Confirm that the Fans are Working

Your computer will become overheated if the fans aren’t functioning properly or can’t circulate air for some reason. If this is the case, you’ll need to take it to a repair shop to have it mended. 

It’s easy to determine whether the fans in your PC are operating correctly or not. The PC begins to operate as soon as you push the power button, and you should hear a pleasing “vroom” sound. That is the sound of the internal fans, which will initially operate at full speed before slowing down as the computer boots.

There is a possibility that the fans aren’t operating properly if you can’t hear the sound when the PC first turns on or if you notice that it is weaker than it’s supposed to be. Once you confirm that the issue is with the fan, take your PC to a reputable computer repair shop. The overheating issue should stop when your fans begin to work normally again.

You can also open up your computer to check the fans’ functionality if you’d like to investigate further. If opening the computer scares you, simply use a flashlight to check the ventilation holes for any active fans. Before the heat melts the components, you should take it to a repair shop right away if you can’t see any fan movement.

A highly conductive substance called thermal paste is typically used between CPU/GPU and metal heatsinks in your PC. This paste makes sure that the heat is effectively dispersed from the computer. 

The cooling system’s efficiency will certainly be impacted if this substance expires in your PC. Also note that the thermal paste on your computer will dry out eventually, especially if you frequently overtax your system. So, if you notice your PC overheating, reapplying thermal paste is one of the beneficial actions that can stop it.

You will need to disassemble your gadget to change the thermal paste because it is housed inside the computer. If you’re not an expert, we’ll advise that you ask a skilled technician to complete this process on your behalf.
