CPU Temperature Error ASUS: How to Fix CPU Over Temperature Error

CPU Temperature Error ASUS – Do you have an ASUS motherboard with an Intel or AMD processor, yet keep receiving a “CPU Over Temperature” error message? Fear not, because this post will serve to do more than only correct that oversight. In addition, you may maintain a low internal computer processor temperature, even while intense gaming.

Apple’s switch from Intel to Apple silicon CPUs has not only made Macs quicker. However, the central processing unit fan was also taken out, thus Apple M1 computers are no longer in need of cooling. Yes, with each new generation, Intel and AMD have created more powerful processors.

Nonetheless, appropriate cooling is essential for these high-end processors. In addition, the central processing unit (CPU) may fail if inadequate cooling is provided. And, a “CPU Over Temperature Error” will be shown. The ASUS motherboard displays this error to prevent harm to the CPU.

It is common for this error to show when you first start up your computer after a restart. This error may also happen if your CPU overheats as a result of very taxing operations. If this problem appears while using the computer normally, it should be cause for worry.

What causes the CPU Over Temperature Error?

When the temperature of all the CPU cores surpasses 100 °C, the ASUS BIOS displays this problem. Plus, neither the heatsink nor the CPU fan can keep the chip at a manageable temperature. The solidified thermal paste/grease might be the blame for this.

If that’s the case, you’ll need to get a new one. There’s also the possibility that the CPU fan isn’t working properly. Yet, there might be more factors causing the high CPU temperature.

Those issues often arise during the summer months in hotter climates. Don’t worry about how well your CPU is cooled. It’s only natural for the central processing unit’s temperature to increase along with the ambient air temperature.

Perhaps the central processing unit (CPU) is overheating because you haven’t given it enough air to breathe. However, dust might also be to blame if you don’t regularly clean your central processing unit. This is most likely due to your CPU being overclocked.

Thermal Throttle and Ideal CPU Temperature.

To prevent overheating, modern CPUs use thermal throttling. Which, if used in time, may prevent permanent harm to your CPU. In the event that thermal throttling is activated. It then adjusts the CPU speed to compensate for the heat it’s producing.

Basically, it slows down the CPU when it becomes too hot, which helps to cool down the chip. Performance loss is inevitable; a good cooling system is essential.

Regularly checking the temperature of your processor is a good idea. Any CPU temperature monitoring programme for Windows is available for free download. The optimal temperature range for a computer running vital programmes is between 65 and 70 degrees Celsius.

And 80-90 degrees Fahrenheit is fine for playing games. But in normal conditions, when the CPU isn’t being pushed to its limits. If the temperature reads between 95 and 100 degrees Celsius, you should be concerned.

If “CPU Over Temperature Error” keeps popping up during marathon gaming sessions, your processor may be overheating. Then you need not be concerned about it. However, while using a computer or laptop normally, this error message often appears. For example, in the midst of browsing the web or viewing a movie on YouTube.

Then, I advise that you try every single one of the suggestions provided in this piece. And I can promise you that the CPU temperature will go down.

CPU Temperature Error ASUS: How to Fix CPU Over Temperature Error

Check CPU Utilization and Perform a Clean Boot

Before you go into the bowels of your CPU and fiddle with some convoluted settings. The task manager is the ideal place to monitor your current CPU load. Right-clicking the Start menu will bring up the Task Manager.

Then, choose “Performance” from the menu. If the processor is already being used at 90% or more. Then the inevitable CPU overheating issue would arise. However, if task manager CPU use is typical, it may be okay. If that’s the case, the hardware has to be replaced.

It’s conceivable that an unidentified background process or external app is the source of the issue.

Maybe it’s malicious software. The best course of action is to first restart the computer cleanly. During a clean boot, Windows loads just the necessary services and programmes. After a clean reboot, you should examine the task manager’s CPU utilisation and the temperature of your computer’s central processing unit (CPU).

Control CPU Fan Speed using ASUS BIOS Settings

The ASUS UEFI BIOS Utility displays more than just the temperature of the central processing unit and the motherboard. In addition, the CPU FAN and CHA FAN speeds are under the user’s command.

Normal operation has the fan speed varying with the temperature of the central processing unit. So, if you use your laptops for a wide variety of purposes, including gaming, work, editing, and online surfing, this may come as a surprise. Because of this, the CPU will run cooler in this mode.

But if you’re always pushing yourself to the limit, you may. In such a scenario, increasing the CPU fan speed to its maximum will help briefly reduce the CPU’s temperature. You may check the CPU fan’s functionality in the BIOS as well.

  1. Prior to doing anything further, be sure the computer is totally turned off.
  2. Start it up again while holding F2 or Delete to boot into the ASUS BIOS setup utility.
  3. Until recently, this information was not available in BIOS Utility, but now you can check the temperature of your CPU there. It’s above 70 degrees Celsius, at least. If it doesn’t work, then you should probably go on to the next option.
  4. All right, after you have recorded the CPU temperature. To adjust the FAN speed, go to QFAN Control and click it.
  5. All of your computer’s CPU fans should now be visible. However, we would want to adjust the CPU fan’s rotational speed. Keep “Full Speed” set for the CPU Fan.
  6. To return to the main BIOS Window, use the Esc key. The CPU’s temperature should have dropped, but test it to be sure. Something is amiss with the CPU fan if you don’t notice any temperature variations. Perhaps a filthy heatsink or fan is preventing the CPU from cooling down.
  7. Return the fan setting to its default state.
  8. Then, save your work and close the programme by pressing F10. After that, Windows will begin loading.

Clean Heatsink/CPU Fan (Cooler)

For me, this was the answer that really helped. The CPU Fan and Heatsink hadn’t been cleaned since I first assembled the computer. As a result, dust had settled in the crevice between the heatsink and the CPU.

As a result, the heatsink was unable to improve heat dissipation from the CPU. Therefore, the heatsink removes and distributes the heat before it may cause the CPU to fail from overheating. It makes no difference whether you’re using the factory CPU fan or an aftermarket CPU cooler.

But if it’s happening shortly after you put together your PC, that’s a red flag. Then maybe the CPU Fan/Heatsink isn’t in the best location. If you don’t know what you’re doing with computers, that is. The next step is to have a professional clean your system.

The central processing unit (CPU) fan of a computer is connected to the CPU heatsink. Therefore, the CPU fan must be disconnected before the heatsink can be cleaned.

  1. Before doing anything further, make sure the computer is totally turned down and unplugged. After that, you need just track down your CPU and its cooling fan on the motherboard.
  2. The CPU fan can be loose, so check that first. The issue lies here if that is the case. In any other case, unplug the central processing unit’s fan from the motherboard.
  3. Then, you may remove the CPU fan by unscrewing it.
  4. Now, with the use of a can of compressed air, remove all of the dust particles from the CPU Fan/Heatsink and the area just above the chip. If you like, you may also use a gentle brush.
  5. That’s all; reattach the fan to the central processing unit. And if you open your computer now, you’ll find that the temperature has dropped.

Change thermal paste/grease

You need also take care of the thermal paste, in addition to cleaning the CPU Fan/Cooler heatsink. A cleaner CPU is a cooler CPU, thus cleaning is a good idea. But if you use a high-quality thermal paste, you may cut it even more. If the CPU’s thermal paste has hardened, a replacement is required. You can get a lot of high-quality thermal paste/grease that also has a cleanser on the market.

Thermal Paste Types.

Thermocouples are often made of metal, ceramic, or silicon. However, ceramic thermal paste is recommended.

Ceramic paste is nonconductive because it does not include any metal. Because of this, ceramic has the added benefit of being less expensive.

But liquid metal thermal paste offers the same degree of cooling. But they should be handled with great caution because of their tremendous electrical conductivity.

The thermal pads are already coated with silicon thermal paste. It may be installed between the central processing unit and the heatsink. As a result, ceramic paste is useful in many contexts.

Is it necessary to change the thermal paste?.

Once every two years, thermal paste must be replaced. On the other hand, if you’re running a high-end processor that generates a lot of heat. Furthermore, once a year, you need replace the thermal paste if the CPU has a high TDP (Thermal Design Power) Value, such as 165W. When the processor’s thermal design power (TDP) is high, it generates a lot of excess heat.

However, if your CPU has a TDP of 55W to 65W, you may let the thermal paste sit undisturbed for up to 2 years. And nowadays, the thermal paste is already put on the Intel standard fan/heatsink. The Thermal Design Power of the CPU may be found on the CPU Maker’s webpage.

How to change thermal paste?.

To wipe the thermal paste off the heatsink and the processor, you need to remove the CPU fan/heatsink. The cleaning required to remove the old thermal paste is often included with the thermal paste itself. Use thermal paste after cleaning the component. Don’t overdo it with the lotion. Otherwise, you’ll see a rise in the occurrence of the CPU Over Temperature Error.

Setup PC Cooling Fans for Proper Air Flow

If a problem persists after you’ve cleaned your brand-new computer, it may be malfunctioning. Then it’s likely that you haven’t given your CPU enough airflow. There’s a chance that your computer casing is trapping heat inside rather than dissipating it. The first step is to remove the cover from your computer’s central processing unit and power up the machine. And now, to keep tabs on your processor’s temperature, use the appropriate programme.

Stop CPU Overclocking

When using the original cooling fans for your CPU during Overclocking. The temperature of your CPU will increase by a factor of 10. Due to the increased workload, an overclocked CPU will eventually overheat. Any programme that attempts to overclock your computer will be disabled after a clean boot. However, if you have overclocked through the BIOS, it is recommended that you return the settings to their factory defaults.


Now you know what to do if you get the message “American Megatrends CPU Over Temperature Error” on your ASUS motherboard. Turn off any overclocking software and do a cold boot first. If it doesn’t solve the problem, make sure the CPU fan is spinning at the correct speed. Once that is done, you may clean the heatsink and reinstall the CPU fan.

It’s also a good idea to use a brush or air blower to thoroughly clean the central processing unit. When it fails, try replacing the thermal paste to see if that helps. Verify the proper installation of any cooling fans. Also, make sure your space isn’t too hot to sleep in. If none of these solutions work, you may also try clearing the CMOS. You may let me know in the comments if the CPU temperature dropped.
