How to Keep Your Computer Cool

When your computer is on, nearly all of its components become hot. Constant exposure to high temperatures can cause serious damage to your computer. Here is a list of ways to keep your PC cool. Check if your fans are running. This is the first step when you find your computer overheating. Open the case, and then check if all fans are still working. If at least one is not working anymore, consider doing repairs or getting a replacement. Regularly clean your computer.

Clean your computer, especially the cooling fan. The fans attached to the computer case are used for the active cooling of the computer. Over time, dust and dirt can accumulate in these fans. The accumulated dirt can slow down or stop fans from working. Some internal parts will eventually overheat if fans fail to expel the hot air fast enough.



To clean your cooling fan:

1. Shut down your PC.

2. Open the computer case.

3. If there is excessive dirt inside the computer case, remove the fan.

4. To clean the fan, You can use compressed air, a small electronic vacuum or duster, or a damp cloth.

5. If you moisten the cloth, ensure the cooling fan is dry or there is no remaining moisture before connecting it again. Clean other computer parts like the monitor, mouse, and keyboard.

Before cleaning any hardware component, ensure your machine is turned off. Otherwise, your computer is susceptible to electrostatic discharge that can damage its parts, and you are also prone to grounding yourself. Before applying any cleaning procedures to hardware, make sure to check its manufacturer’s manual to see if they have provided you with the recommended instructions for cleaning or maintaining it. Do not spray or spill any liquid directly into computer parts.

Do not limit the airflow around your computer. Place your computer in a room that can provide sufficient airflow. Ensure it does not sit next to other objects that prevent air circulation, like walls or computers. There should be at least two to three inches of space on both sides. Since most of the hot air comes from the air vent at the back end of the computer case, this part should be obvious and open.

Move your computer to a cooler and cleaner environment. Move your PC to a place with proper ventilation. The physical location mustn’t contribute further heat to the computer. Ensure your PC is not placed near a furnace, refrigerator, cooking appliances, or other things that can blow hot air or transfer heat into your computer system.

To prevent your PC from overheating, it is advised to place it in an air-conditioned room. Note: Be careful when moving your computer to avoid damaging sensitive components inside it, such as the CPU, graphics card, hard drive, and motherboard.

Use your computer with the case closed. Letting the case open while the computer is running seems logical to keep it cooler. This is true. However, dirt and dust will accumulate and clog the computer fans faster when the case is opened. This can cause the fans to slow down or fail at cooling your computer.

Upgrade your CPU fan. The CPU is the most important component inside the computer. When running demanding applications, the CPU and graphics card induce more heat. It can get so hot that it can be cooked. Consider purchasing a high-quality and larger CPU fan that can keep the CPU temperature lower than the pre-built CPU fan in your computer.

Consider installing a component-specific fan to cool down if you observe that the other components are overheating. You could also consider installing a case fan.

This small fan can be attached to the computer case’s front or back. There are two types of case fans: one that draws cooler air into the case and one that expels warm air. Installing both is a great way to cool your computer.

Turn off your computer when not in use. A laptop continues to produce heat as long as it is running, even if you aren’t using it. If you only have a few minutes of inactivity, set your computer to hibernation. It will also turn off your computer, but the opened files and programs are stored on your hard disk.

The major upside of keeping your computer cool is that it can help you avoid expensive repairs or unnecessary upgrades. Also, unplug external hardware that you no longer use, like printers and scanners. Overheating can destroy and shorten the lifespan of components inside your computer.
