What Are CPU Overheating Symptoms and How to Fix them?

In this era of electronics, we rely on computers for every single work. Whether it is about surfing, YouTubing, emails, or online classes, we all depend on computers to get through. And, every action of your Computer is controlled by the CPU. Sometimes, you may experience overheating of your CPU because of over usage or lack of proper ventilation. Here, I will share with you what CPU overheating symptoms are and how you can fix them.

CPU Overheating symptoms

If the CPU remains overheated for an extended period, your processor may get damaged permanently. People are often not aware of the overheating symptoms of CPU, hence generally not able to save it before permanent damage. If you know the signs of overheating of the CPU, you can easily protect it from further damage.

CPU Overheating Symptoms

You may be able to figure out that your CPU is overheating by keeping an eye on these symptoms:

  1. Your system slows down- If your system takes time to operate a particular function or it starts hanging, you can worry about the high temperature of your system.
  2. CPU fan is running faster than usual- The work of the CPU Fan is to cool down the high temperature of the CPU. So, if the CPU Fan is spinning more quickly than the average speed, your CPU may be overheated.
  3. System shuts down automatically- If you boot up your PC and it shuts down automatically after a short time, there is a possibility of overheating the CPU.
  4. Touch your CPU- Touch your PC from its backside. If it feels hotter than usual, there is a guaranteed possibility of your CPU to be overheating.
  5. The monitor screen turns blue- If your computer screen suddenly turns blue and your system abruptly shuts down, you need to worry—this clear symptom of overheating the CPU.

How to fix CPU Overheating

So, what to do now when you have checked all the symptoms of overheating your CPU? You need to sort it out quickly. I am going to reveal how you can fix CPU overheating in minutes.

Check CPU Fan

Check whether the CPU Fan is mounted correctly to the motherboard in the right place. You should also check the position of the blades; are not they lose or fallen. Sometimes CPU Fan is not spinning because of some cable connections obstructing its rotational path. If there is any obstruction, remove them. You should also clean dirt from the fan blades so that proper spinning of Fan is ensured.

Check ventilation

CPU overheating can also be due to poor ventilation of the system. The hot air is continuously thrown out through the vents. If the vents are obstructed by dust or debris, hot air will not get away to the outside. So, if your CPU is overheated, you must check the ventilation first. Remove any cables or debris obstructing the vents to throw hot air outside.

Check BIOS

Check the BIOS settings. If you have changed it recently, there is a possibility of overclocking or something wrong happening. Change the BIOS settings to default. But before changing the BIOS settings, you should take a screenshot of the current settings. This is done to ensure no further disturbance in the settings if the default doesn’t work well. Even if this does not work for you, try updating BIOS. I hope it will help to fix CPU overheating.

Check thermal solutions

If you are using thermal solutions for your system, check its compatibility with your system. The thermal solutions which are installed in your system should be specific and compatible with your CPU. Check that the CPU heatsink thermal interface is covered with any protective layer. Ensure thermal solution is not bumping into other parts of the motherboard.

How to fix CPU overheating

How to prevent Overheating of CPU

You have learned about CPU overheating symptoms and how to fix them. But if I tell you that you can already prevent your CPU from overheating, will you agree? Yes, by following some simple tips, you can avoid your CPU getting very hot.

Keep your CPU in the cooler area

Sometimes overheating is because of hotter surroundings. For avoiding this, you should always place your PC and CPU in the cooler area of your house.

Use a power supply of good quality 

When you use a poor power supply, a massive part of the power is lost as heat. Because of this inefficiency of inadequate power supply, your CPU gets hot. So, better for you to opt for a suitable power supply.

Shut down your system after use

Many people leave their PC in sleep mode when they finish their work. This leads to the useless consumption of power, making the CPU overheated. So, if you are away from your PC for several hours, you should shut it down.

Keep PC clean from inside

If the inside of your PC is filled with dirt, it will affect the system’s efficiency. So, if you want your PC to run properly and avoid CPU from overheating, you must keep it clean

Place PC in proper ventilation

Always put your PC on a table or desk, where there is nothing around for at least 10-15 centimeters. Open surroundings can help in proper ventilation and will avoid overheating.

Double check liquid cooling

If you are using liquid cooling for your Computer, then check it properly from time to time. Regular checkups can ensure better cooling and avoidance of overheating.

keep an eye on CPU Fan

Keep a regular check on the CPU fans’ proper running. Clean dirt from the blades of fans to keep them efficient. CPU Fans play an important role in keeping the CPU temperature at normal.


There are many other factors you can keep in your mind to keep your CPU protected from overheating. Never use PC inside blankets or making an angle with its bottom. Always use PC being placed on a flat and smooth surface, just like of desk or table. Avoid over usage of CPU. Don’t run lots of programs at once. Keeping these points in mind can help you identify CPU overheating symptoms and prevent your PC and CPU from overheating.
