What is a CPU Over Temperature Error ?

It occurs when the processor is operating at a higher temperature than it was configured to handle. Heat can damage the internal components of a computer, and overheating processors are particularly susceptible to permanent damage if temperatures climb too high. As such, most CPUs come with built-in safeguards that reduce their clock speed when they get too hot, or cut power entirely as needed in order to prevent further head buildup in an effort to save the component.

If a user encounters an over temperature error message, it is recommended they look into solutions such as ensuring their system runs in cool, well-ventilated rooms or investing in PC cooling solutions like extra fans and vent covers.

What causes a CPU Over Temperature Error Randomly?

CPU Over Temperature Error Randomly

There are many potential causes of this error – from dirty or damaged coolers and heat sinks to high input voltage due to overclocking, the possibilities can be overwhelming. Here is a breakdown of the most common causes of this error.  

Improper Fan Speed 

The most common cause for a CPU over temperature error is an improperly functioning fan. The fan helps to keep your computer cool by blowing away hot air from inside the case, so if it’s not working properly, heat can quickly build up and cause an issue. To check if your fan is working correctly, open your computer’s case and observe its speed — it should be running at full speed or close to it. If not, then you may need to replace it. 

Dirty or Damaged Coolers and Heat Sink 

Another common cause for CPU temp too high is dirty or damaged coolers and heat sinks. These are components responsible for dissipating heat away from the CPU and keeping it cool enough to operate without any issues. Over time, they can become clogged with dust and dirt, which reduces their effectiveness in cooling the processor down. Cleaning these components regularly is important to ensure they remain in good condition and can do their job properly. 

Dried Out Thermal Paste 

Thermal paste is another important component when it comes to cooling your CPU down —it acts as a bridge between the processor and cooler/heat sink, allowing for better heat transfer between them. But if this paste dries out over time due to incorrect usage or prolonged exposure to high temperatures, then it won’t be able to do its job effectively anymore — resulting in higher than normal temperatures for your processor. Replacing thermal paste regularly is recommended for optimal performance. 

Blocking the Computer’s Vents 

Blocking one or more of your computer’s air vents can also lead to a CPU over temperature error as well as other issues such as slowdowns or crashes due to overheating components inside the system unit. Make sure all vents are clear of dust and debris so that air can flow through freely without any blockages in order to maintain optimal performance levels on your machine. 

High Input Voltage/Overclocking 

High input voltage can cause an issue with your processor if it is not designed to handle it properly. This is often seen when users try to “overclock” their processor by setting higher voltages than what is recommended by the manufacturer. This process requires caution as it can lead to instability and other problems such as overheating if done incorrectly. It is best to leave it for expert users who understand what they are doing! 

How to tell if your Computer is Overheating?

Overheating is a serious issue for computer systems, as it can lead to permanent damage and expensive repairs. Many individuals overlook the warning signs that the CPU is overheating, because the symptoms do not always indicate a problem with the temperature. It’s important to pay attention to when your computer experiences any of the following: 

  • Unusual fan sounds
  • Crashing or hanging during use
  • Blue screens at any time
  • Constantly restarts or shuts down unexpectedly 
  • Increases or sustains a high temperature while in an idle state. 

If you experience one or more of these conditions, monitor your CPU’s temperature before considering other problems.

Fixing CPU Over Temperature Error in 6 Steps

Solution 1: Keep It Clean

Keeping your CPU clean is an important step in helping to avoid temperature errors. A few simple steps can have a big impact on maintaining the health of your CPU. To start, use a can of compressed air to blow out the dust from your CPU heatsink. This will help increase air flow, decreasing stress and temperatures — improving performance in return. Additionally, using a larger PC case with multiple fans could also prove beneficial for pulling more heat out of the case before it has a chance to build up and cause an over temperature error. 

Solution 2: Check for Adequate Ventilation

To avoid CPU temp too high issue, you need to make sure it has adequate ventilation; it’s important to leave enough space between your CPU and any other nearby heat sources like radiators, electric heaters and windows. Crowding the machine can cause air circulation to be blocked, preventing the necessary cooling and causing overheating issues. Leave at least a few inches between your CPU and these objects to allow for maximum airflow.

Solution 3: Try To Keep Your Room Cool

Ensure that the room temperature where your PC is located is cool and comfortable. Fans draw in a set amount of air, expel it, and then cycle out. If the temperature of your environment is too high, it puts more strain on your components, making bits run hotter than intended and thus leading to CPU over temperature error popping up on your screen. Always keep your room at or below about 75º Fahrenheit for an optimal computing experience. This will give you fewer chances for defective components due to overheating and greater performance overall. 

Solution 4: Check Thermal Paste and Reapply If Needed

Thermal paste helps to increase the performance and lifespan of your computer by creating better heat transfer between a CPU and its cooler. It’s typically made up of metal, ceramic and silicon compounds so it’s important to choose high-quality products from renowned brands. To check if you need new thermal paste, unscrew the CPU fan and heat sink to examine them closely. If the paste appears to be dried or hardened, then it needs replacing. When reapplying the paste, make sure it’s evenly distributed for optimal cooling effects.

Solution 5: Stop Overclocking

Overclocking a CPU can sometimes be appealing since it allows for more efficient processing power. However, it puts additional strain on the parts and increases your risk of developing an over temperature error leading to component damage. To avoid this problem altogether, you should never push your processor beyond its speed limit. If you are noticing temperature issues, lower down the clock speed or increase the cooling component’s output. Make sure that all components are suited to handle the maximum temperature they will reach while overclocked. Always ensure proper airflow throughout your hardware as well before attempting any type of overclocking.

Solution 6: Change The Fan Speed

For a quick fix to your CPU over temperature error, changing the fan speed is a good place to start. This can either be done by using a compatible program or manually changing the settings in your PC. Using a program will allow you to not only monitor the current temperature of your computer but also control when and how fast the fans spin. Keep in mind, not all motherboards have this capability so manual changes may be the answer.
