Some computer components get quite hot during operation. Sometimes, this overheating prevents the operating system from starting or warnings are displayed on the startup screen, as an example “CPU overtemperature error”.. In this post, we will explain how to identify the cause of this problem and how to fix it in various ways.
What to do when the error appears “CPU Over Temperature Error”
Error “CPU overtemperature error” indicates that the CPU is overheating. The warning is displayed while the operating system is starting and after pressing the key. F1 Boot continues, but even if the operating system has started and works fine, you should not leave this error unchecked.
Overheating detection.
First, you should check if the CPU is truly overheated, since this is the main and most common cause of the error. User must monitor CPU temperature. This task is carried out with the help of special programs. Many of them show data on the heating of some components of the system. How viewing occurs most frequently in idle time, In other words, when the processor performs the minimum number of operations, the temperature should not exceed 50 degrees. For more information on how to check the CPU temperature, check our post.

Checking for CPU overheating
If it really is an overheating, there are several alternatives to help for this case. Let's see them in detail.
Method 1: clean the system drive
Over time, dust accumulates in the system unit, causing a decrease in the performance of certain components and an increase in the temperature inside the case due to insufficient air circulation. In particularly dirty units, debris keeps the refrigerator from speeding up enough, which also has the effect of increasing temperatures. For more information on how to clean debris from your computer, check our post.

Method 2: change thermal paste
Thermal paste must be changed every year, because it dries up and loses its properties. It stops dissipating heat from the CPU and all work is done solely through active cooling. If you haven't changed the thermal paste in a long time or never, there is almost a hundred percent chance that it will. Follow the instructions in our post and you will be able to do it without problems.

Method 3: buy a new refrigeration
The fact is that the more powerful the processor, more heat generates and needs better cooling. If after the two previous methods they did not help, then all you have to do is buy a new refrigerator or try to increase the RPM of the old one. Increasing speed will have a positive effect on cooling., but the refrigerator will make more noise.

When it comes to buying a new refrigerator, the first thing to pay attention to is your processor specifications. You must start with its heat dissipation. You can find this information on the official website of the manufacturer. In our post you will find a detailed guide on how to select a cooler for your CPU.

Method 4: update BIOS
Sometimes, this error is generated when there is a conflict between the components. Older BIOS version cannot work properly with newer CPU versions when installed on older revision motherboards. If the processor temperature is normal, all you have to do is update the BIOS to the latest version. Read more about this procedure in our posts.

We have studied four alternatives to solve the error. “CPU overtemperature error”. To sum up, we would like to point out that this failure is almost never caused by anything, it is related to the processor overheating. Despite this, if you have made sure this warning is false and the BIOS update path did not help, you can just ignore it and ignore it.
We are glad we were able to help you with the problem..
