Part 2. What May Cause a Computer to Overheat


Dust is the one of the major cause of computer overheating problem. Dust is a very good insulator of heat and if your computer components are covered with heat, they won't be able to dissipate it. When they are not able to dissipate heat, they will overheat and start causing some troubles. A computer or laptop covered in dust will have a reduced lifespan than the one that is clean. If you are also experiencing computer overheating problem, then check to see if it is covered with dust or is experiencing some other problem.

Improper Ventilation

A computer may also overheat if there is not proper air ventilation to the internal components. This may be due to a variety of causes. First is dust buildup that blocks the air vents or cooling fans openings. Or it may also be due to the malfunctioning of cooling fans. No matter the reason, improper air ventilation is also a major cause that can cause computer overheating problem.

Faulty Components

Certain computer components produce a lot of heat as they work. These include CPU and power supply. The reason for it is that they are the most used components of the computer. Usually, there are cooling systems like fans and air vents to keep CPU cool and avoid overheating. If the fan is faulty and doesn't work the way it should, it can cause the computer to overheat. Overheating of components may also cause due to the faulty heat sink. The heat sink is a device that absorbs heat from components and dissipates it elsewhere- usually air or liquid coolant. But if the heatsink is damaged or not the specified one for your computer, it won't perform its work properly. It is recommended that you always get the recommended heatsink and fans for your processor.

Over Usage

A computer may also overheat if you are continuously using it for many hours without letting it have a break. For example, you have been playing a high-resolution game for continuously for the past 4-5 hours or more, the CPU may be overused and can generate the abnormal amount of heat. If the computer overheating problem is due to it’s over usage, then shutting it down in-between for some time can help give it time to cool down and reduce the excess heat generated.

Inappropriate Location

The location of your computer/laptop may cause it to overheat. Even if the cooling fans of the computer/laptop are working properly, it can still overheat if it is placed in a hot temperature. This can be when you don't have proper ventilation in the room where it is kept or are using your laptop in a car, beside a fireplace or outside in sunlight. The effect of exterior conditions on your computer/laptop can be dire and cause such problems.

Part 3. 10 Ways on How to Do When Computer Overheats

Computer overheating problem is associated with poor ventilation and cooling issues. If you are suffering from computer overheating problem, the first step is to identify the cause and then take appropriate steps to solve it. Below are given 10 ways to prevent your computer or laptop from overheating.

1. Remove the Dust

Cleaning the accumulated dust the components of your system can solve the overheating problem that you may be facing. Dust is the major cause of computer overheating as it is a heat insulator. It doesn't let the heat from components dissipate, causing them to overheat. Moreover, they can also block air vents on the case or fan case. Follow the steps to clean your computer of dust.

1. Open the case.
2. Get a compressed air can and spray it on air vents to open them.
3. Use a cloth to clean the visible dust.
4. Use a vacuum cleaner to suck out the dust from sensitive components.

2. Allow Proper Air Ventilation

If you have cleaned your computer and it suffers from overheating, it may be due to improper ventilation. Make sure that your computer isn't obstructed by any obstacle on either side. There should be at least 2-3 inches of free space on both sides and the back must be fully open. Most of the heat is dissipated through the back, so make sure that you give it enough space to remove hot air. You can also add additional fans to improve air ventilation. In the case of a laptop, don't use it on soft surfaces like Sofa or a cushion as it can block the fan below and the heat will not be dissipated. This will cause it to overheat.

3. Check the Computer Fans

Every computer has minimum two fans installed in it to keep the things cool. One cools the CPU and the other comes in the power supply. If you don't have additional fans with our computer case, then power supply fan is the only thing that will remove heat from your computer. If it doesn't work, then it will cause the computer to overheat. If CPU fan doesn't work, it will cause the processor to heat overly and can damage it. You can check the power supply fan by placing your hands on the computer case. If you feel air coming from it, then it working. If not, then you may have to replace the power supply to solve the issue. If the problem is with the CPU fans, follow the below steps.

• First, open the case of the computer.
• Check if the fan is installed correctly.
• Make sure the push pins are in its recommended positions.
• Check the wiring to see if the fan is receiving power or not.

4. Check the Heat Sinks

Computer overheating may also be caused due to incorrectly installed heat sinks or old thermal paste. Open the computer case and see if the heatsinks are properly seated. If yes, the problem may be due to old thermal paste. Remove the heat sink and apply the new thermal paste to the surface. Then again seat the heat sink and check if it has any effect.

5. Keep the Case Closed

One of the most believed misconceptions about overheating is that removing the case can solve the problem. Well, it can at first but will eventually make the problem worse in the long run. The cause of this is that it will make the components more vulnerable to dust and dirt which will actually worsen the problem. If dust clogs the air vents or fans, then keeping the case open will do more damage than good.

6. Keep It in a Cool Environment

Moving your computer to a cool place can reduce the heating problem. Usually, if you use a computer in a hot room with poor ventilation or in the car, or beside a fireplace, it will increase the heat produced by the computer. But if you keep your computer in a fully ventilated or air-conditioned room, the air ventilation will improve; cool air will reach the components, eventually cooling them. If the components of your computer remain cool, they will perform better and errors and freezes will be rare.

7. Upgrade to a More Powerful CPU Fan

CPU is the most important and the costliest component of a computer. But it is also the component that heats up the most in the computer. That’s the reason why it has a dedicated CPU fan, to protect it from damage from overheating. But if your computer is an old one and you haven't replaced the CPU fan even once, you may encounter computer overheating problem. A factory installed CPU fan can only as much as keeping the temperature of the CPU low even when it is working at full power. If the fan is malfunctioning, it could put your computer at a risk of being fried. To prevent something like from happening, buy and install a more powerful CPU fan from various manufacturers that can keep the temperature lower than the factory made fan can do.

8. Forbid Overclocking

Your computer comes with predefined sets of configuration from the manufacturer which operates them at an optimum. It is to keep them safe from overloading. But it doesn't mean that you can't tweak your CPU or RAM to operate at higher speed than normal. it is possible to do that through BIOS settings and this process is called overclocking. But overclocking also has its disadvantages. It causes the computer to overheat and the system becomes unstable and more prone to crashes and errors. If you haven't done anything to deal with the rising temperature, it would be best to change the settings to default.

9. Replace the Power Supply

Every power supply has a built-in fan that is used to remove heat from the computer. If your computer doesn't have a case fan, then this is the only way to cool the heating components. The power supply also has a limited age and it won't work forever. Usually like other components, it will also start to break down the older your computer gets and eventually stop working. If your power supply stops working, your computer will start overheating and will cause trouble. It can also burn up the computer components. So it is advisable to replace the power supply when you find a computer overheating problem with your system.
