How To Fix CPU Overheating Issue in Laptop

If you are facing CPU is overheating issue then read this guide. Excess of heat puts pressure on the CPU and can slow down your PC. CPU Overheating can automatically shut you PC down, which can lead to sudden data loss and long-lasting permanent damage to its components. If your CPU is overheating, this guide will help you fix it.

Perhaps the most typical source of laptop overheating is poor ventilation. Under normal conditions, you can avert overheating by checking the degree of liquid in the system and keeping it correctly. There are some things that can lead to computer overheating. We will try to mention them all in this blog article.

Fix CPU Overheating Issue in Laptop/PC

There are a number of ways to confirm the temperature of the CPU. Abnormally significant temperatures may also be due to a range of different problems so it’s advised to have the vehicle properly diagnosed to be certain of the issue. The perfect temperature of the processor depends upon the PC brand and model type, and one should be aware of it to prevent inadvertent issues.

What are the signs of CPU overheating?

  • If there are unusual fan sounds coming out of your PC, then your CPU is overheating.
  • If you find your PC is hanging, crashing and having a blue screen too often.
  • If your PC always shuts down or restarts by itself.
  • If even in idle or sleep mode, it has a high temperature.

Much like with desktop computers, they need a way to expel the hot air created by their components. If your laptop keeps shutting itself down, have a hint that it may be shutting down to guard itself against thermal damage and examine the environment you’re operating in.

What are the temperatures applicable to CPU overheating?

  • If your CPU is under 60°C then its in a good state
  • If your CPU is 60-70°C, then it is running okay
  • If your CPU is 70-80°C, then it is still manageable
  • If your CPU is 80-90°C, then it is not in a good state
  • If your CPU is over 90°C, then that’s an overheating warning!

Here are the methods to fix CPU overheating :

Method 1: Clean the dust

One of the primary reasons for CPU overheating is the dust settling in its components, especially the internal fans, because dust seriously affects heat dissipation. So the most effective way to keep your PC cool is to open your computer case, clean the dust in the internal fans. It is also recommended that you clean the dust on the graphics card and the RAM should with a brush. This will prevent it from overheating again.

Method 2: Check your thermal paste

Thermal paste is generally a highly conductive material that is applied between CPU/GPU and heatsinks. The old thermal paste being no longer effective is one of the primary reasons for the CPU overheating.

Check your thermal paste

Therefore, you should get the thermal paste replaced. If your PC  is still under warranty, you should not do it by yourself. If your computer is out of warranty, and then you can take the chance. Following is the guide to replace thermal paste :

  • First, you need to shut down your computer and completely cut off the power.
  • Then you need to open your computer case.
  • After that, clean the dust inside.
  • With care, remove the fan gently.
  • Then you need to wipe the CPU and clean off the old thermal paste.
  • Now you must clean your hands.
  • Carefully, you need to put a little thermal paste on both sides of the CPU and the fan. It is recommended to put a small amount only
  • Now put the fan back
  • Finally, close to your computer case.

Method 3: Check your cooling system

There is an inbuilt cooling system in PCs as the computer during regular use generates heat. This system helps to keep components at a stable temperature and let them work normally.

If this cooling system fails to do its job, then the heat generated by the PC will keep building up and cause your CPU overheated. So if you clean the dust, but your CPU still maintains a high temperature, you should check the cooling system. If it is not working correctly, you will need to fix it or replace the system with a new one.

How to fix the Air-flow cooling system

There are two cooling systems on a PC.  While one is the Air-flow cooling system, the other is the Liquid-cooled system.

The air-flow cooling system comes in two parts: fans and heat sinks. A heat sink is a piece of metal that provides surface area for air. Once the  CPU makes heat sinks hotter, the fan sends the hot air out of the PC case.

The heat sink is inefficient, and the fan has stopped working then you must replace it with a better sink and new fans. If the air circulation is low, you should get an additional cooling system.

Method 4: Set a reasonable power option

Sometimes when you let the CPU run at full load for a long time, the CPU produces more heat. For this, a reasonable settings and effective power management method is required to keep your PC at an optimal temperature. By doing this, you are not only fixing the CPU overheating but also saving power.

Method 5: Stop overclocking

Overclocking is a way to speed up CPU or GPU, therefore testing the limit of its capabilities and making the component perform more operations per second. This makes the component generate far more heat than usual. So if your CPU is overheating when you’re overclocking it, you must throttle back the overclock and cool down your CPU. You can also set System settings to default to prevent future overclocking.

Method 6: Check if there is proper ventilation for the air to go out

There should be zero blockage from other materials near the vents of the PC. The hot air should be able to get out without any issue. This will prevent the CPU from overheating. You must never place your PC on blankets, beds or any other soft surface while working. What these smooth and uneven surfaces do is block the airflow from the vents, which results in warming up the PC. So make sure the ventilation area is never blocked

Final Thoughts :

You should never ignore an overheating CPU as your PC will experience a decrease in system performance and eventually give out. Therefore it should be a top priority to keep your CPU cool and maintain a manageable temperature. Here’s hoping this guide helped you fix your overheating CPU.
