You might see the “CPU Over Temperature” error as soon as you turn on your computer. Well, this error could be caused by a number of things, but the most common is that your CPU is too hot. You might only see this error once, and then it might be gone the next time you turn on your computer. But if this error keeps coming up every time you turn on your computer, it’s best to figure out why. So, how do you fix CPU Over Temperature Error?
To fix CPU Over Temperature Error, try fixing the heatsink, slowing down your CPU or upgrading your CPU cooler, cleaning the inside of your PC case, or reapplying thermal paste to your CPU.
But if you keep reading, we’ll talk about why CPU Over Temperature Error happens, how to fix it, and what you can do to fix this error.
What makes the CPU Over Temperature Error happen?
When all of the CPU cores reach 100 °C, the ASUS BIOS shows this error. And the CPU fan or heatsink can’t cool the processor down. This might be because the thermal paste or grease has become hard. Then you have to get a new one. Or, the CPU fan might not be spinning at the right RPM. But the high CPU temperature could be caused by something else.
Users usually have these kinds of problems in hot places in the summer. No matter how good your CPU cooling system is, this will happen. If the temperature in your room is very high, the CPU temperature will also go up. Or, it could be that you haven’t given the CPU enough air to breathe. Also, dust can be a problem if you don’t clean your CPU every so often. If you have overclocked your CPU, this is definitely the problem.
- The heatsink is not sitting right on top of the CPU.
- CPU Speeded Up
- Not a good CPU cooler
- Inside the heatsink, dust builds up.
- Using a computer in a very warm place
- Thermocouple paste
When is an error about the CPU’s temperature not a big deal?
Don’t worry if you see the message “CPU over temperature.” The problem is not always dangerous.
Let’s say you’ve been playing games for hours on your system and it gets hot. There are many things that stop heat from escaping, like dust on the CPU fan that keeps it from spinning right. Because it is hot in the summer, the system usually heats up quickly, making the inside of the case warmer than usual.
In this case, this error message is likely to show up. So, you don’t have to worry about it.
When is it dangerous to have a CPU Over Temperature Error?
Even if you don’t play high-intensity games or do anything else that puts a lot of stress on the system, you should pay attention to this error message if it comes up often in normal situations. If you get this error message, you should figure out what is wrong.
Suppose you’re just watching YouTube or a movie on your web browser when your system reboots and gives you an error message that says “CPU over temperature.” You should find a way to check the temperature and find a solution.
Follow the steps below to fix the CPU Over Temperature Error when the message starts to bother you.
How to Fix the CPU Over Temperature Error?
Upgrade Your CPU Cooler
If you are using the CPU cooler that came with your CPU, you may have trouble controlling the heat. Using a stock cooler might not be a good idea, especially if you have a CPU with a lot of cores.
Especially if you are a gamer or someone who often uses complicated programs, you should spend a little more on a better CPU cooler. If you are using an Intel stock CPU cooler, you should switch to a custom CPU cooler instead.
When compared to stock CPU coolers, aftermarket CPU coolers can take in more heat. If you like to overclock, you should get a high-end CPU cooler that uses air or liquid.
Keep in mind that the CPU Over Temperature message means that your CPU is running at a temperature that is too high or too low. So, if you replace your stock CPU cooler with a custom CPU cooler, the temperature of your processor will drop by a lot.
Repairing the heatsink
Most of the time, if your CPU is getting too hot, it’s because of the heatsink. This problem can be fixed by taking the heatsink off and putting it back on. A heatsink that doesn’t fit tightly won’t be able to get rid of the huge amount of heat coming from your CPU.
The heatsink on your CPU is very easy to move around. All you have to do is take off the screws on your heatsink and put it back on your CPU so that it touches the top of your CPU.
If you don’t know how to do this, there are a lot of tutorials on YouTube that can help you put the heatsink on your CPU the right way.
Setting the CPU clock speed to the default
There’s no doubt that overclocking your CPU can make it run faster, but it also makes it make more heat. And if you use a cheap CPU cooler, you may end up getting a CPU Over Temperature error when you try to turn on your computer.
So, if this is true, it’s best to set your CPU’s clock speed to Default Clock Speed. Now that you’ve done this, your CPU will produce less heat. You can keep an eye on your CPU’s temperature with a reliable program like HWMonitor.
If there is a lot of dust inside your PC case, the temperature inside can go up. Dust soaks up more heat, which makes the temperature rise. Because of this, it’s best to use a fan blower to get rid of any dust inside your PC case. You can also use a can of compressed air to blow out the dust from your CPU heatsink.
You could also use a large PC case with multiple fans to pull more heat out of the case.
Put your computer close to a window
When you use your PC in a hot room, more heat can sometimes build up inside the case. Even so, the fans on your PC case are doing their job by pulling in fresh air from one end and pushing it out the other. Hot, humid air slows down the cooling process, though.
And if you live in a hot, humid place, put your computer near an open window so that fresh air can flow into the case. If you’re using a tower PC case, I’d suggest taking off the side panel and putting it in front of the window.
Putting on more thermal paste
This is the best way to bring your CPU’s temperature down. Keep this as the last choice on the list, though. Intel says that it’s best to put new thermal paste on your CPU once a year. If your CPU is running hotter than usual, removing and reapplying the thermal paste can help a lot to bring the temperature down.

The CPU over temperature error is very common and happens to almost all computers at some point. There are times when you can ignore it without putting your motherboard’s parts at risk. But if it happens a lot under normal circumstances, it should be taken seriously.
You can try to fix this problem in a number of ways, both with software and hardware. If you know a little bit about computers, you won’t need a tech expert to help you. So, you now know what to do when your computer gives you the CPU over temperature error.
