How To Fix CPU Over Temperature Error

Just as humans need a functional Brain to survive and efficiently carry out day-to-day tasks, a computer needs a CPU to function efficiently. 

The CPU on your computer controls everything and does all the computations necessary for your programs to function. 

However, when a CPU overheats, it may lead to abnormalities in its operation and you might start seeing errors like “CPU over temperature error” or “processor not supported”.

This article will show you certain important things you could do to fix the CPU over-temperature error. 

When the CPU temperature exceeds the set limit, ASUS computers with American Megatrends motherboards display the error message “CPU Over Temperature Error.” 

This restriction guards against system crashes that could harm the CPU and this error is shown to you by your computer so that you can troubleshoot it.

This problem could arise from time to time if you use your computer’s resources more than it can handle. 

The next section will properly highlight some of the causes for the CPU over-temperature error that may pop up on your computer. 

Usual Causes for CPU Over Temperature Error

Below are the most expected causes of this computer error. 

• The high CPU input voltage, which is usually a result of overclocking.
• CPU or thermal sensor damage.
• Using the wrong fan speed.
• Heat sinks and coolers that are dirty or broken.
• When the heat paste has dried.
• Blocked computer vents. 

You’ll be glad to know that when this error appears on your computer, you don’t necessarily have to go through extreme measures to fix it. 

There’s a simple thing you could do to clear the error, if this doesn’t work, then you could go ahead to try the other actions we’ll share soon. 

So, when your computer shows the CPU Over Temperature Error, you must immediately turn off your computer and leave it alone for a couple of hours so that the CPU can cool down.

After some time, turn it back on after that to see if the error still occurs. If it does, you should try any of the suggestions shown below. 

How To Fix CPU Over Temperature Error

Ensure Your Computer Has Proper Airflow

After around 30 minutes, if you start getting the “CPU over temperature” error, there might be a problem with where you’re placing your computer. Your CPU will continue to heat up if your computer is placed in an area that heats up quickly or if its vents are obstructed.

Running resource-intensive programs will quickly cause your CPU to reach the temperature threshold if you don’t have a good cooling system.

To avoid such problems, you must maintain optimum ventilation and keep your PC in a cool environment. 

Below are five things I’d advise you to do for your computer in this regard. 

• To avoid obstructing the vents on your laptop, place it on a firm, flat surface rather than your lap, fabric, or carpet. 
• For better ventilation, keep the desktop CPU case away from the walls as much as possible.
• Keep your computer out of the sun.
• Maintain a clean and well-ventilated workspace.
• Try to keep and use your computer in cooler environments, preferably one with an air conditioning system. 

Check and Clean the CPU Cooler and Heat Sink

Overheating is just one of the numerous issues that a dirty system is at the heart of. Dust buildup in heatsinks or fans restricts airflow, which causes heated air to circulate inside the case.

Dust is extremely sensitive to electrons, thus it is very important to clean the dust and wipe all the filth from your system. Dust can harm the chip because of the charming electric charge in addition to causing the overheating issue.

The CPU over-temperature error may also arise if your CPU cooler, fan, or heatsink is malfunctioning. In such circumstances, they are unable to dissipate the CPU’s heat effectively, resulting in this boot error.

Therefore, you must ensure that the CPU fan and heat sink are properly positioned and that their screws are securely fastened.

Reseat Heatsink With Properly Applied Thermal Paste

The heatsink on the CPU cooler must be positioned correctly to dissipate the chip’s heat. 

 Another factor that may cause overheating of your computer is the dried-out thermal paste.

So, in the case of an incorrect positioning of your computer’s heatsink, you can follow the steps below to reseat it properly.

• First, and most importantly, turn off your computer and remove all of the cables from the case.
• Next, The casing’s side panel should be opened.
• Depending on your cooler, carefully detach the heatsink from the motherboard.
• Carefully blow the dust from the heatsink or radiator and clean the cooler’s fan.
• Use careful pressure to remove the old thermal paste off the chip using isopropyl alcohol.
• Put some fresh thermal paste in the chip’s middle, about the size of a pea.
• Reinstall the heatsink properly right above the chip. 
• Lastly, you can clip back the heatsink to the motherboard of the computer. 

Adjust Your Overclock Settings

It’s a good idea to overclock (OC) your CPU to achieve the maximum performance possible. However, the device will quickly overheat if you overclock it beyond its safe operating range. In these circumstances, you must reduce the overclocking settings to a suitable level. 

Although, in the case of a lower-grade computer, you should just disable overclocking. 

Overclocking can mean bad news for your computer since it uses more energy and produces more heat. You can check the temperature after you cease overclocking the CPU to see if the error still appears.  

Now, if you overclock your CPU using a program, you may also use it to reduce the clock rate while if you use the BIOS, you can go to the BIOS and reduce the CPU’s input voltage.

Also, note that totally resetting your BIOS is necessary if you are using an old system and need to completely disable OC.

Delid CPU

If you’re using a desktop computer, you can also try delidding the CPU to move it nearer the heat sink if you experience this Cpu Over Temperature Error.

 By doing this, the heat sink is better able to dissipate the heat generated by the CPU.

However, there is a chance that delidding a CPU all by yourself as an amateur will harm it. 

So, we recommend you do extensive research on how to properly delid a CPU before plunging in or call a computer technician to get it done. 

Replace Device

If your computer displays this error even when your CPU is not overheating, your thermal sensor may have developed a fault. 

Additionally, your CPU might be faulty if your computer won’t boot at all and keeps displaying the aforementioned error.

In such cases, you must immediately remove and replace the bad CPU. Yet again, it’ll be safer to consult a qualified computer hardware technician to do this for you. 

Examine The Fan In The BIOS.

Whenever the CPU over-temperature error problem arises, the first thing you should do is check your BIOS and the fan speed. 

This boot issue will occur if your fans are not spinning at a fast enough rate to adequately cool the CPU.

To prolong the life of the fan, many motherboard manufacturers have added a new feature called Zero Fan Speed in the BIOS. In that case, the fan won’t turn on until it reaches a greater temperature.

And due to the fact that the chip was already heated, this causes overheating.

 In this scenario, accelerating the fan’s speed through the BIOS can help solve this problem. 

Final Remarks 

You don’t have to push your computer to the curb or run to a computer technician whenever minor errors like the CPU over temperature error occurs in your computer. 

As seen in this article, you can follow simple steps and suggestions to clear certain errors that may appear on your computer screen. 

So, as regards this error discussed in this article, you can try to avoid it as much as you can, and if it happens anyway, these suggestions shared here will help you clear this computer error in no time.
