CPU Overheating Fix – 5 Ways On What To Do When Computer Overheats

Are you facing CPU overheating issues? Do you want to know how to fix it? Most people’s computers or laptops are their lifelines, without which they cannot do their daily tasks.

Computers and laptops have become essential to your daily life, especially if you work from home. However, as vital as it is, you must take adequate care of your equipment if you want it to last a long time. Overheating is a big issue that you will face as a computer owner.

Computer overheating is a big issue that can reduce your computer’s performance or possibly fry its internal components. This might eventually result in the loss of critical data saved on the computer or laptop.

Part 1. How to Diagnose Whether Your Computer or Laptop Overheating

Overheating your computer can cause major harm to it and the loss of crucial files and data. Money spent on purchasing new components will likewise be considered an unnecessary waste. To avoid anything like this from happening, you may regularly check your computer for overheating issues. Many software tools, such as HWmonitor, can monitor the temperature of your computer hardware for this reason.

1: Download and install HWmonitor on your desktop or laptop computer.

2: Once the installation is finished, run the utility.

3: Under the temperature option, you can monitor the temperature of various components, such as the motherboard, CPU, and others.

Part 2. What May Cause a Computer to Overheat


One of the most common causes of computer overheating is dust. Dust is an excellent heat insulator, and if your computer components are covered in it, they will be unable to dissipate it.

They will overheat and cause problems if they are unable to dissipate heat. A dust-covered computer or laptop will have a shorter lifespan than a clean one. If your computer is also overheating, check to see if it is covered in dust or if it is experiencing another problem.

Improper Ventilation

A computer can potentially overheat if the interior components are not properly ventilated. This might be attributed to several factors. The first is dust accumulation, which obstructs air vents or cooling fan apertures. It might also be the result of cooling fans failing. Whatever the reason, improper air ventilation is a major contributor to computer overheating.

Faulty Components

As they function, certain computer components generate a lot of heat. CPU and power supply are examples of this. This is because they are the most frequently utilized computer components. Cooling solutions like fans and air vents are often used to keep the CPU cool and minimize overheating.

The computer may overheat if the fan is malfunctioning and does not function properly. Overheating of components may also occur as a result of a malfunctioning heat sink.

The heat sink is a device that absorbs heat from components and distributes it elsewhere, often through the use of air or liquid coolant. However, if the heatsink is broken or not the correct one for your computer, it will not function correctly. Getting the specified heatsink and fans for your processor is usually advised.

Over Usage

A computer may also overheat if you use it continuously for long periods of time without giving it a break. For example, if you have been playing a high-resolution game for the past 4-5 hours or more, the CPU may have been overworked and may have generated an abnormal amount of heat. If the computer’s overheating problem is caused by excessive use, shutting it down in between can help give it time to cool down and reduce the excess heat generated.

Part 3. 5 Ways on What to Do When Computer Overheats

Poor ventilation and cooling issues are linked to computer overheating. If you have a computer overheating problem, the first step is to identify the cause and then take the necessary steps to resolve it. The following are ten ways to keep your computer or laptop from overheating.

1. Remove the Dust

Cleaning the collected dust on the components of your system might address any overheating issues you may be experiencing. Dust is the most common cause of computer overheating because it acts as a heat insulator. It prevents heat from components from dissipating, causing them to overheat. Furthermore, they might obstruct air vents on the case or fan case. To clean your PC of dust, follow the instructions below.

1. Begin by opening the case.
2. Using compressed air can spray air vents to open them.
3. Wipe away any visible dust with a towel.
4. Suck away the dust from delicate components using a vacuum cleaner.

2. Allow Proper Air Ventilation

If you have cleaned your computer and it still overheats, it might be due to poor airflow. Make certain that your PC is not hindered on either side. Both sides should have at least 2-3 inches of empty room, and the rear should be completely open. The majority of the heat is dispersed through the rear, so ensure sure it has adequate area to expel hot air. You may also increase air ventilation by installing more fans. When using a laptop, avoid placing it on soft surfaces such as a sofa or a cushion, since this might obstruct the fan underneath and prevent heat from being dispersed. It will overheat as a result of this.

3. Check the Computer Fans

To keep things cool, every computer has at least two fans installed. One cools the CPU, while the other enters the power supply.

If you do not have any additional fans with our computer case, the only thing that will remove heat from your computer is the power supply fan. So, if it does not function properly, the computer will overheat.

If the CPU fan fails, the processor will overheat and may be damaged. Place your hands on the computer case to check the power supply fan. If you can feel air coming from it, it’s working. If not, you may need to replace the power supply to resolve the problem. Follow the steps below if the problem is with the CPU fans.

First, open the computer case.
Verify that the fan is properly installed.
Check that the push pins are in the proper positions.
Examine the wiring to see if the fan is receiving power.

4. Check the Heat Sinks

Overheating in a computer can also be caused by improperly installed heat sinks or old thermal paste. Examine the computer case to ensure that the heatsinks are properly seated. If so, the issue could be due to old thermal paste. Remove the heat sink and replace it with the new thermal paste. Seat the heat sink once more to see if it has any effect.

5. Keep the Case Closed

One of the most widely held beliefs about overheating is that removing the case will solve the problem. Yes, at first, but it will exacerbate the problem in the long run. This is because it makes the components more susceptible to dust and dirt, exacerbating the problem. If dust accumulates in the air vents or fans, leaving the case open will cause more harm than good.
