CPU Overheating Issues? Here How To Fix

Is your computer getting too hot? As time passes and technological goods become obsolete, they cause significant problems, and the computer is no exception. Normal heating is not a problem because it is an electronic device that operates on electrical impulses. However, there will be energy loss in the form of heat energy.

Perhaps you’re playing high-end games or using software that necessitates a higher spec than your standard machine. You’re placing pressure on your gadget, which will cause it to overheat.

We will discuss some of the most effective ways to deal with overheating and how to diagnose overheating in your computer.

How To Fix CPU overheating issues

Here are a few ways to fix CPU overheating problems. Although these methods are effective, you’ll have to visit a technician even if the problem persists.

1. Check the Fans

If fans of your PC is not spinning the hot air will be trapped inside, causing it to heat more.

Make sure the fans are spinning properly and feel the air moving. 

If the fans aren’t rotating or don’t appear to be moving much air, turn off the computer and clean the fan blades using compressed air. Dirt is the primary cause of fans slowing down or stopping completely. Even if the fan does not appear to be working, you will need to have it repaired at a repair shop.

2. Install a liquid cooling system or purchase a cooling pad for your laptop.

A liquid cooling system is another option for dealing with CPU overheating. The water cooling system is more efficient compared to air cooling system.

Folks who overclock the CPU to achieve more performance typically use a liquid cooling system. If you have this type of cooling system installed, make sure to check it regularly.

3. Placement of the Computer

A PC is frequently placed in a room with no ventilation or fresh air source. The room becomes heated, especially in the summer, and because there is no fresh air, the PC begins to heat up.

Many computer desks have small cubbies or recesses where the computer can be placed. It will also assist in keeping your PC cool if you keep the room temperature low.

Avoiding using your computer on a bed or carpet is another technique to keep it cool. A laptop’s vents are normally found on the side or bottom of the machine.

If you leave your laptop turned ON your bed or carpet, the vents on the machine may become blocked.

Place your laptop on a hard surface that allows the computer’s vents to dispel the hot air.

4. Clean dirt on PC

CPU Overheating Issues

If you haven’t cleaned your computer in a while, dirt is most likely to blame for the overheating. To clean your PC effectively, remove the rear cover and use compressed air to clean the debris gathered on the surface. Make sure the vents are clean as well for proper airflow. Because dirt accumulates over time, it’s important to clean your computer regularly to avoid system failure due to overheating.

5. Reapply thermal paste

Reapply thermal paste

Thermal paste is a highly conductive compound used to connect the CPU/GPU to the heatsinks. This paste guarantees that heat is effectively dissipated from the computer. When this material ages, it will have a negative impact on the cooling system’s efficiency.

Most common mistake newbies make is that they apply very less or too much thermal paste. You only need enough paste to fill in the heatsink and the CPU gaps, but not so much that it spills out the sides.

6. Speed Up Fan Speed

There’s also the option of accelerating the cooling system faster than usual. You can use the free program to keep track of and manage the speed of your computer’s fans. The application allows you to manually regulate or use presets to control the speed of your PC fan.

You may also set it to regulate fan speed automatically based on your computer’s current temperature.

Regrettably, it does not work on all PCs. Because some motherboards don’t allow you to alter fan speed, this option might not be available to you.

How to Monitor the Temperature of the System

Your computer may have a CPU Thermometer that beeps when the temperature rises too high.

If your computer doesn’t have a built-in case thermometer, download and install a free CPU temperature monitor tool like SpeedFan, Core Temp, or CPU Thermometer. The temperature of your CPU is displayed as a number in this program.

The maximum temperature a computer should attain varies based on the CPU type, but it should normally be between 50 and 80 degrees Celsius.

The temperature should be substantially lower when the computer is not in use and is not running the program.

Use any third-party software to monitor your CPU temperature so you can figure out which program is heating it up the most. There are lots of software that can help you with temperature measurements.

This article will go through one of the most common third-party options for diagnosing CPU overheating issues.

Core Temp is a piece of software that shows you how many cores it has, how much power it consumes, and the average temperatures for each of its cores.

What are the signs of CPU overheating?

There are various reasons why your CPU and GPU are overheating, including running it for an extended period of time, performing tasks that need high-end computation, and CPU overloading. Overheating should not be taken lightly because it might result in irreversible internal damage and costly hardware replacements.

Here are some indicators that your computer is overheating.

1. Monitor Speed of Fans

Monitor Speed of Fans

Listening to the fans is the first technique to tell if your CPU is overheating. Your CPU fan shouldn’t be running at full speed most of the time.

As your CPU warms up, the fans speed up to carry hot air away from it faster.

Suppose you notice that the fans are exceptionally loud and quick. In that case, it’s time to boost the ventilation because the computer is getting hotter.

2. The PC’s performance is sluggish.

You’ll notice that your PC’s performance has degraded, and it’s having trouble doing simple activities.

If you observe that specific applications that demand more resources and compute are loading more slowly, for example.

When a processor gets too hot, the system pushes it to run at a reduced frequency to limit heat production. This is known as CPU throttling. As a result, overall performance suffers.

Task Manager can be used to check for CPU throttling. Go to task manager and look for performance at the top. There are graphs and parameters such as utilization, and more.

If you launch a video editing or gaming program, you’ll notice a difference in usage. You’ll notice a dramatic dip in performance when the utilization approaches 100%.

3. Random Shutdown and Restart

Modern CPUs are intended to shut down immediately in the event of extreme overheating. The minimum temperature that the CPU must reach before it is forced to shut down is usually rather high, about 80-90 degrees Celsius or higher.

4. Internal Factors

Heating can be caused by many different internal and environmental factors. A faulty fan or an insufficient cooling system could be the interior cause. Another cause could be an old CPU that has been installed inside the computer.

Running high-end computing apps and games are also major causes of CPU overheating. To combat the issue, employ a more effective cooling system when playing high-graphics games on a PC with poor specs.

Another cause is CPU and GPU overclocking, which is a strategy for improving CPU performance. In simple words, overclocking involves pushing the CPU/GPU beyond the manufacturer’s specifications. Although this procedure improves efficiency, it also promotes CPU overheating.

5. External Factors

External factors include the computer’s placement and the room’s airflow. In the summer, a closed room will heat up more, and the room will lack fresh cool air due to a lack of sufficient ventilation.

Dust can build up within computer cases, preventing air circulation.

As a result, the risks of a laptop overheating are higher than those of a desktop PC. However, if you clean your computer regularly, your PC may not overheat.

You can also use a free temperature monitoring program to boost the fan speed.


I hope this post was useful in resolving your computer’s overheating problems. All of the strategies listed above are extremely effective at cooling down the computer. If your computer does not appear to be cooling down, you will need to see a professional. It’s possible that some internal components have been damaged and need to be replaced.
