What Happens When CPU Overheats

Wanna know what happens when CPU overheats? Overheating is the major issue that effects lifespan and internal parts of the CPU. Read on to know more about it.

The CPU (Central Processing Unit) is the brain of any computer. It’s what makes your computer work, and it can’t function properly without a cool head. If you’ve ever watched an episode of “How It’s Made” on TV, then you’re probably familiar with how CPUs are made—they’re created by pouring molten metal into molds called ‘dies’.

The dies are shaped like tiny mountains with little valleys in between each mountain peak. These valleys represent the pathways where electricity flows through your CPU to do all its work for your PC or laptop.

CPU overheating can cause serious damage to your computer, which is why you must know how to prevent it from happening. If your CPU does overheat on its own, the best thing for you to do is contact a professional so they can inspect what caused the problem and fix it for good!

But if you’re able to detect overheating before it causes major, irreversible damage to your CPU, then read on for our tips and tricks on how you can prevent this from happening.

CPU Overheating [What Happens When CPU Overheats]

A computer’s processor is the brain of the machine, and it can’t function at its best when it overheats. If you notice that your computer has been shutting down or running slower than normal lately, this may be due to an overheating CPU. To prevent damage to your device, here are some tips on how to cool down your CPU:

What Happens When CPU Overheats
  • Clean out dust from vents by using compressed air can – Dust build up in vents will obstruct airflow and increase heat output, so these areas must be kept clean and clear for optimal cooling performance.
  • Unplug peripheral devices – Connecting multiple devices such as printers or external hard drives can cause a power surge which will trigger the fan to run at a high speed. Disconnecting these devices can help decrease the amount of power required to operate your computer, and will reduce the fan noise in most cases.

Why Does Computer Overheating Occur?

It is important to know how to identify the signs of a computer that is overheating and what you can do to prevent it. Computers are designed with internal fans, but these fans only provide so much airflow. Overheating occurs when the heat generated by components such as processors, graphics cards, and power supplies exceeds the rate at which air moves across them due to inadequate cooling or poor thermal design.

The computer’s internal fans may not be enough to cool the system down, and this can cause permanent damage or slow performance. Since computers generate a lot of heat during normal operation, you need to make sure that your system is ventilated and that the fans are not blocked.

The main cause for computer overheating can be poor airflow caused by dust build-up inside the case (ducts and vents), lack of maintenance from users who keep their computers in closed rooms, and failure to use the computer on a flat surface.

The fan speed increases when it detects that air is not flowing through the case fast enough or if there are any high-temperature components. However, this may cause more dust build-up which can seriously damage your system over time. Airflow issues usually accompany overheating, so make sure that your computer is always clean and dust-free.

A fan could be faulty or the thermal paste used to join it with a heat sink might have dried up which causes poor cooling performance. You can either open up the case and reapply the fresh thermal compound or replace the fan if necessary.

Don’t keep your computer in a closed room or at the bottom of a pile of other stuff. Also, make sure that you’re using it on a flat and stable surface with good airflow around it.

How to Check the Temperature of your CPU?

What Happens When CPU Overheats

One of the most important parts of a computer is the CPU. This component regulates how fast your computer can operate, and if it overheats from working too hard then it can cause damage to other components as well as slow down performance significantly.

To keep your CPU running at its highest potential, you need to be able to monitor its temperature so that you can take action when necessary. Here are some tips for checking the temperature on your CPU.

1. Check the CPU fan and make sure it is spinning:

The fan is one of the easiest ways to monitor whether or not your CPU is overheating. If it’s spinning at full speed, then that means your CPU is cool. If it’s spinning slowly, then that means the CPU might be getting too hot and you should monitor this closely to make sure that doesn’t happen.

A fan can become obstructed by dust or other debris, so if it’s not spinning at full speed then you should clean it out. You can also use programs like Speccy or Open Hardware Monitor to check the CPU fan speed in real-time, or you can just look at your taskbar and see if the program is running whilst checking on your computer frequently for key signs of overheating.

If your CPU fan isn’t spinning then that means that your computer isn’t getting enough cool air to keep the CPU at a safe temperature. If you want, you can also install and use an aftermarket cooler for direct cooling of the CPU itself. You should make sure there is nothing blocking airflow around your PC or on top of it as well which could cause overheating issues due to poor ventilation.

2. Check to see if your computer has a “thermometer” icon in the taskbar:

Many modern computers come with built-in thermometers that allow you to quickly check the CPU temperature without having access to software like Speccy or Open Hardware Monitor. The thermometer will usually be in the bottom right-hand corner of your taskbar and look like a small slanted rectangle with a number inside of it. The higher the temperature, the more slanted the rectangle will become, and if you click on it then a new window should pop up letting you know the current temperature.

If your computer doesn’t have a built-in thermometer or if it isn’t showing an accurate temperature, then you can still check the temperature from software like Speccy or Open Hardware Monitor as discussed above.

In general, a safe CPU temperature is around 60 degrees Celsius. If it gets much higher than that, then there might be a problem with your computer and you should take action immediately to prevent damage to other components.

The best way you can monitor your CPU temperature is by using software like Speccy or Open Hardware Monitor, accessing the built-in thermometer in your taskbar, or checking to see if there is a “thermometer” icon. You can also use an aftermarket cooler if you feel like your CPU is overheating. The higher the temperature, the more slanted the rectangle will become in a thermometer, and you should always take action to prevent damage.

3. Open up the Task Manager and check for high CPU usage (this can indicate overheating):

The Task Manager is another very useful tool for checking the CPU temperature, and it’s usually located in your taskbar or by pressing Ctrl+Shift+Esc. If you do not already know, it’s a small window that shows all of the programs and processes currently running on your computer. The name of the program will be in the top left, and a percentage reading of how much CPU power it is using will be located just below that.

If you see a process on your Task Manager list that has 100% usage then this might indicate overheating problems. You can right-click on any items with high percentages to find out more information about them, including their location on your computer.

If you want to solve this issue then one of the best ways is by using a cooling pad or installing an aftermarket cooler for direct CPU cooling. You should also make sure there isn’t anything blocking airflow around your PC and that nothing is resting directly on top of it either since poor ventilation can cause overheating.

In general, a safe CPU temperature is around 60 degrees Celsius. If it gets much higher than that then there might be a problem with your computer and you should take action immediately to prevent damage to other components. You can check the Task Manager for high percentages to determine if your PC needs an aftermarket cooler or not.

What Happens When CPU Overheats


One last thing to remember is that if the computer gets too hot, you might not be able to do much of anything on it. When a CPU overheats and shuts down due to high temperatures, there’s no way for your device’s fans or liquid cooling system to keep up with all the heat being generated by your laptop.

Even if they could, sometimes this would just cause other components (like graphics cards) in the machine to overheat as well. The best thing you can do? Stop using your PC until it cools back down! If you’re trying to put out a fire right now and need some help closing apps running in the background of Windows 10 just click here! We hope we’ve helped make this issue clear.

If you are still experiencing problems, try running an antivirus scan on your computer. You may also want to consider purchasing a cooling pad or laptop cooler as well as cleaning out any dust from inside of your PC’s vents/grills with compressed air (make sure not to use too much pressure). Try restarting your computer after doing all these steps – sometimes this will help cool down the system enough that it won’t overheat anymore.
