You should, however, be worried if the message keeps popping up more often than not, as it could indicate a problem with your hardware. As such, you must take the necessary steps to address this issue early rather than later.

What causes the CPU over temperature error?

If it’s your first time seeing the CPU over temperature error, it can be worrying. Some of its main triggers include:

Overclocking – While overclocking your CPU can improve its performance, sometimes it comes with an overheated CPU. This is especially true if you have an old processor that cannot handle that much pressure. Faulty cooling system – Your cooling system may not provide the much-needed air, which ultimately causes the CPU to overheat. Clogged heat sink – A heat sink helps absorb heat from the processor and spread it across a larger area to prevent build-up. If it is clogged with dust, it will no longer be effective at pulling away heat from your processor. Too much stress on the CPU – If you’re running multiple programs at once, all of this activity can put a lot of stress on your processor and cause it to overheat quickly.  Poor ventilation – If your computer doesn’t get enough airflow through its vents, it will overheat quickly.  Degraded thermal paste – If you have had your PC for a while, the thermal paste might have degraded over time and needs replacing before it worsens and leads to permanent damage.

The CPU over temperature error can happen when restarting your PC, after installing a new build, or even randomly. Below are some ways to address it.

How can I fix the CPU over temperature error?

We recommend that you try out the following before moving on to the main solutions:

Make sure your PC has plenty of space around it so heat can escape easily. Check out the best PC cases for efficient airflow. If you have recently added new hardware or software to your system, remove it and try booting again to see if this resolves the issue. Turn off unnecessary applications to free up more RAM for better performance of your system. Test your PC for stress to ascertain its performance metrics. Update all drivers on your computer, including motherboard chipset drivers, video card drivers, etc. Shut down your computer and wait for at least 3 minutes before turning it back on.

1. Clean dirt 

Dust can cause overheating and reduce the cooling effect of the fan. To clean it out, use a can of compressed air or a vacuum cleaner. You can also use a brush to remove dust from the vents on the back of your laptop. Cleaning off the vents on your laptop can help improve airflow and prevent dust from clogging up those vents. You can also use a soft cloth or other non-abrasive cleaning material to wipe down all areas around your vent openings.

2. Disable overclocking 

Overclocking is making your computer run faster than its normal speed. While it can be a useful tool for gamers and other people who want their computers to be as fast as possible, it can also cause problems if done incorrectly. SPONSORED If you’re using a laptop, overclocking will increase battery drain and heat output. This can damage your laptop’s components over time. Your processor also plays a huge role when it comes to overclocking.  If you have an old processor, avoid overclocking at all costs. Alternatively, you install overclocking monitoring software to keep tabs when your CPU is being overworked and stop the process.

3. Replace thermal paste

Over time, the thermal paste can dry out and lose its effectiveness. When this happens, air pockets will form between the heatsink and the CPU, preventing heat from dissipating properly.  Since the thermal paste transfers heat from your CPU to the cooler, your CPU will overheat if it cannot perform its functions efficiently. Changing out your thermal paste can help cool down your CPU. If the CPU over temperature error appears often, it could indicate early signs of CPU failure. Granted, your CPU will not serve you forever, so you need to be prepared for such eventualities. That’s why we recommend some of the best Windows 11 CPUs with impeccable performance.
