Fix CPU over temperature error

You can solve CPU over temperature error by following these steps:

Check the temperature in BIOS

Your computer’s BIOS (Basic Input Output System) is a program that is stored on a chip on your motherboard. It provides some basic functionality for your computer, such as starting up your operating system and checking the over temperature of your CPU. You can check the temperature of your CPU in the BIOS by restarting your computer and pressing a key when prompted.

The temperature of your CPU is important because it can affect its performance. If your CPU is too hot, it may start to slow down or even shut down to protect itself from damage. You can help keep your CPU cool by ensuring that there is plenty of airflow around it and by keeping its surroundings clean.

Update the BIOS

The BIOS is a program that is stored on a chip on the motherboard. It controls how the computer starts up and how it communicates with the other hardware components. A BIOS update can fix problems with the computer, or add support for newer hardware.

If your computer is over temperature, you should check to see if there is a BIOS update available. Some motherboard manufacturers have their own websites where you can download BIOS updates. If there is not an update available from your motherboard manufacturer, you can try searching for one from another source.

It is important to make sure that you are downloading the correct BIOS update for your specific motherboard and CPU combination. If you install the wrong BIOS update, it could cause even more problems with your computer.

Clean your system

It is important to keep your computer system clean. This means keeping the CPU fan clean and dust-free. A dirty fan can increase CPU over temperature by a few degrees. The best way to clean the fan is to use a vacuum cleaner with the brush attachment. Be sure to hold the vacuum cleaner at least 2 inches away from the fan. You can also use a can of compressed air to clean the fan.

Dust and oil particles can insulate the heat sink, preventing it from optimally dissipating the over temperature produced by the CPU. This is why it is important to clean your heat sink and CPU fan regularly.

You can use a compressed air duster to remove any dust or debris from the heat sink and fan. Be sure to avoid getting any liquid inside of the computer, as this can damage the internal components.

Clean boot

When upgrading your computer’s operating system (OS), you may find that your computer is incompatible with the new OS. This can often happen when trying to install a new version of Windows on an older computer. In this case, you will have to do a clean boot.

  • To do a clean boot, you will need to restart your computer and press F8 before the Windows logo appears. Then, select “Safe Mode with Networking” from the menu.
  • From there, open the Control Panel and go to System and Security -> Administrative Tools -> System Configuration.
  • Under the “Boot” tab, check the box for “Make all boot settings permanent”. Then, click on the “OK” button.

Your computer will now restart in Safe Mode. You can then try installing the new OS again.

Check if the CPU fan is connected to the CPU_fan header

Motherboard manufacturers understand the importance of keeping your computer’s internals cool. That is why most motherboards come with multiple fan headers for the CPU fan, optional fans, and chassis fans. If you’re not using all of the headers, it’s important to check and make sure that the CPU fan is connected to the CPU FAN header. This will ensure that your computer will be properly cooled.

Check thermal paste, replace if necessary

One of the key components of a CPU cooler that often gets overlooked is the thermal paste. This paste is applied between the CPU and the cooler to help with heat transfer. If your thermal paste is old or dried out, it can cause your CPU to over temperature.

To check your thermal paste, remove your CPU cooler from your computer and take a look at the top of your CPU. There should be a small square or rectangle of thermal paste in the center. If it’s black or dry, it’s time for a new application. Be sure to use a quality thermal paste like Arctic Silver 5 if you decide to replace it.

Ensure you have the right cooler for your CPU

Building a PC is an exciting process, but it’s crucial to get the right cooler for your CPU to ensure that it’s properly cooled. Cooling is especially important for gaming and other high-end applications, so make sure you factor in the cost of a good cooler when budgeting for your new PC. There are many great coolers on the market, so do your research and find one that fits your needs.

If you’re looking for a high-performance cooler, be sure to get one with the capacity to efficiently cool your CPU. Some of the best coolers can keep CPUs up to 50 degrees Celsius below ambient temperature, which can make a significant difference in performance. If you’re not sure which cooler is right for you, ask an expert at your local computer store or online forum.

Check if the CPU fan is mechanically damaged

A CPU fan that isn’t spinning correctly can cause the computer to over temperature. If the fan is not spinning at all, then it’s likely that the fan blade has become damaged and will need to be replaced.

If the fan is spinning but not moving enough air, then it’s possible that the fan blade has become stuck and will need to be cleaned or replaced. In either case, it’s a good idea to check if the CPU fan is mechanically damaged and needs to be replaced.

Check for hardware issues

Your computer’s hardware may be the root of the CPU over temperature error. Checking for hardware issues is the first step to resolving this problem.

Make sure that your computer’s fans are working correctly and that there is enough airflow in your case. If there is not, you may need to install additional fans. Additionally, make sure that your computer’s components are properly cooled. If they are not, you may need to apply some additional cooling methods, such as a CPU cooler or water cooling system.

Restore the CPU clock speed to default

A CPU is a very important part of a computer. It is responsible for running the programs that make your computer work. When you overclock your CPU, you are asking it to do more than it was designed to do. This can cause the CPU to run too hot and damage the chip. To avoid this, you need to install a liquid cooling system to keep your CPU cool.

Reset your PC

If you’re having issues with your PC, there are a few things you can try before resetting it. You can try restarting your computer, updating your drivers, or running a system scan. If those things don’t work, then you can try resetting your PC. This will restore your system to its default settings and hopefully fix the problem of over temperature error. Keep in mind that resetting your PC will delete all of your files and programs, so be sure to back them up first.

This will restore your system to its original state, and may fix any problems you’re experiencing. To do this, follow these steps:

  • Shut down your PC.
  • Unplug the power cord from the back of the PC.
  • Wait for 30 seconds.
  • Plug the power cord back in to the PC.
  • Turn on your PC.
