CPU Over Temperature Error

As soon as you switch on your computer, you may see a “CPU Over Temperature” error message. It’s possible that your CPU is overheating, but that’s probably not the case.

This error message may only appear once, and then disappear the next time you start your computer. But if you see this error message every time you boot up your computer, you should investigate the cause. The question then becomes, “How do you resolve the CPU Over Temperature Error?”

If you’re getting a “CPU Over Temperature Error,” you can try repairing the heatsink, slowing down your CPU, updating your CPU cooler, cleaning the interior of your PC case, or reapplying thermal paste to your CPU.

Keep reading, however, and I’ll explain what causes the CPU Over Temperature Error and what you can do about it.


The CPU Over Temperature Error: How to Fix It?

The CPU Cooler Must Be Updated.┬áKeeping the heat under control can be challenging if you’re only utilising the stock CPU cooler that comes with your processor. If your CPU has a large number of cores, you may want to consider replacing the stock cooling.

Spending a bit more on a better CPU cooler is worth it, especially if you are a gamer or someone who frequently utilises complex programmes. Change to a custom CPU cooler from Intel’s stock cooler if you’re using one.

Upgraded CPU coolers have a greater thermal capacity compared to their standard counterparts. Overclockers should invest in a premium air or liquid CPU cooling.

Remember that if you get the CPU Over Temperature notification, the temperature of your processor is either too high or too low. The temperature of the processor can be reduced significantly by installing a bespoke CPU cooler in place of the stock cooler.

Heatsink Maintenance

If your CPU is overheating, the heatsink is probably at blame. Just removing the heatsink and replacing it will solve the issue. If the heatsink doesn’t fit securely, it won’t be able to dissipate the excessive heat produced by your central processing unit.

You can freely relocate your CPU’s heatsink. It’s as simple as reattaching the heatsink to the CPU by removing the screws and positioning it so that it rests on the chip.

There are numerous video guides on YouTube that will show you how to correctly instal the heatsink onto your CPU if you are unsure of how to do so.

Restoring the Factory Settings for the CPU Clock Speed

Overclocking your CPU might make it operate quicker, but it also causes it to generate more heat. Furthermore, a CPU Over Temperature error may appear if you use a low-quality CPU cooler.

If this is the case, leaving the CPU’s clock setting at the manufacturer’s default is your best bet. As a result of your actions, your CPU will no longer overheat. Using a trustworthy tool like HWMonitor, you can monitor your CPU’s temperature.

The Elimination of Dust

Your computer’s internal temperature may rise if there is a lot of dust inside the case. The increased absorption of heat by the dust raises the temperature. That’s why it’s recommended that you use a fan blower to clean out your computer casing whenever dust accumulates there. Compressed air can also be used to remove dust from the CPU heatsink.

If you need to remove even more heat from your PC, a big case with several fans is your best bet.

Location of a Window near the Computer is Recommended.

Using a computer in a warm room might increase the internal temperature. However, rest assured that your computer case’s fans are actively doing their job, drawing in cool air from one side and exhausting it from the other. However, cooling is slowed by hot, humid air.

In addition, if you reside in a particularly hot and humid region, you should position your computer near a window to allow cool air to enter the chassis. Tower PC cases typically have removable side panels that can be positioned in front of the window.

Adding More Thermal Paste to the System

By far, this is the most effective method for cooling your CPU. However, this should remain the last option under consideration. Intel recommends replacing your CPU’s thermal paste once per year. To reduce the temperature of a CPU that is running hotter than usual, removing and reapplying the thermal paste is often helpful.


Almost every computer experiences the CPU over temperature problem at some point. Sometimes you can ignore it without endangering the components on your motherboard. However, it needs to be addressed carefully if it occurs frequently under regular conditions.

There are several software and hardware solutions you might try to address this issue. There is no need to hire a professional tech support staff if you have even a basic understanding of computers. If your computer ever displays the “CPU over temperature” message, you now know what to do.
