How to Overcome PSU Overheating and Prevent PC Component Damage

PSU (Power Supply Unit) is one of the important components in a PC, as it is responsible for providing stable and sufficient electrical power for all other components. However, PSUs can also experience serious problems, namely overheating or overheating.

Overheating can occur due to various factors, such as poor PSU quality, damaged PSU fans, accumulated dust, or too high a power load. Overheating can cause various negative effects, such as decreased PC performance, blue screen, self-restart, or even permanent damage to the PSU or other components.

Therefore, it is very important to know how to deal with PSU overheating and prevent damage to PC components. In this article, I will explain some steps you can take to solve this problem, namely:

• Checking the temperature of the PSU and other components
• Clean dust and dirt from PSUs and PCs
• Replace a damaged or noisy PSU fan
• Replace thermal paste on CPU and GPU
• Reduces power load on PSU
• Replacing PSUs with better and compliant ones

Checking the Temperature of the PSU and Other Components

The first step you have to do is to check the temperature of the PSU and other components, such as the CPU, GPU, motherboard, and RAM. Too high a temperature could be an indication that there is a problem with the PSU or other components. You can use some software that can monitor PC temperatures, such as HWMonitor, SpeedFan, Open Hardware Monitor, or AIDA64. This software can display temperature, voltage, fan speed, and other information about your PC.

The normal temperature for PSU is around 40-50°C, while for CPU and GPU it is around 60-80°C.  If the temperature of the PSU or other components exceeds normal limits, then you should immediately take measures to cool them. If not, then the risk of damage will be even greater.

Cleaning Dust and Dirt from PSUs and PCs

The second step you can take is to clean dust and dirt from the PSU and PC. Dust and dirt can accumulate inside PSUs and PCs, especially in fans, heatsinks, and ventilation holes. Dust and dirt can impede airflow and reduce the cooling ability of PSUs and PCs. In addition, dust and dirt can also cause short circuits or poor connections between components.

To clean dust and dirt from PSUs and PCs, you can use several tools, such as brushes, cloths, or air compressors. You should shut down and unplug the PC from the power source before cleaning it. You should also be careful not to touch sensitive parts, such as pins, sockets, or capacitors. You can follow these steps to clean your PSU and PC:

• Open the PC case and remove the PSU from the PC. You can disconnect the cables connected to the PSU, or remove the screws that secure the PSU.
• Clean the outside of the PSU with a soft, dry cloth. Do not open the PSU, as that can be dangerous and could void the warranty.
• Clean the PSU fan with a brush or air compressor. Do not turn the PSU fan by hand, as that may damage it. If the PSU fan is noisy or damaged, you will need to replace it with a new one.
• Clean the inside of the PC with a brush or air compressor. Remove dust and debris from fans, heatsinks, motherboards, RAM, GPUs, and other components. Do not spray the air too tightly or too closely, as that could damage the components.
• Reinstall the PSU and PC. Make sure all cables and components are well connected and tightly. Close the PC case and turn on the PC.

Replacing a Damaged or Noisy PSU Fan

The third step you can take is to replace a damaged or noisy PSU fan. The PSU fan is one of the components that most often have problems because it works constantly to cool the PSU. A faulty or noisy PSU fan could indicate that it is not working properly, and could cause the PSU to overheat. A damaged or noisy PSU fan can also interfere with your comfort when using a PC.

To replace a damaged or noisy PSU fan, you must purchase a new PSU fan that matches your PSU specifications. You should also open the PSU and replace the old PSU fan with a new one.

However, you should be careful, because opening a PSU can be dangerous and can void the warranty. You should also make sure that you have enough knowledge and skills to do this. If not, you can ask for help from experts or experienced technicians.

Here are the steps to replace a damaged or noisy PSU fan:

• Turn off and unplug the PC from the power source. Open the PC case and remove the PSU from the PC. You can disconnect the cables connected to the PSU, or remove the screws that secure the PSU.
• Open the PSU by removing the screws that close it. You should be careful not to touch sensitive parts, such as capacitors, that can store electricity. You should also wear gloves and protective goggles for your safety.
• Remove the old PSU fan by removing the cables and screws connecting them. You should note the position and color of the cables connected to the PSU fan so that you can reconnect them correctly.
• Install the new PSU fan by connecting the appropriate cables and screws. Make sure the new PSU fan is the same size, voltage, and current as the old one. Otherwise, it could cause problems with your PSU or PC.
• Close the PSU by reattaching the screws that close it. Reinstall the PSU and PC. Make sure all cables and components are well connected and tightly. Close the PC case and turn on the PC.

Replacing Thermal Paste on CPU and GPU

The fourth step you can take is to replace the thermal paste on the CPU and GPU. Thermal paste is a material used to increase thermal conductivity between a CPU or GPU and a heatsink or cooler attached to it.

Thermal paste can reduce heat resistance and help cool the CPU or GPU. However, thermal paste can also dry out, crack, or wear out over time, and can reduce its effectiveness. Bad thermal paste can cause CPU or GPU overheating and can affect the PSU as well.

To replace the thermal paste on the CPU and GPU, you must buy a new, quality thermal paste. You’ll also need to open the PC and remove the heatsink or cooler from the CPU or GPU. You should clean any old thermal paste residue from the CPU, GPU, and heatsink or cooler with a clean cloth and alcohol.

You should apply the new thermal paste in the right way and according to the manufacturer’s instructions. You’ll need to tightly reattach the heatsink or cooler to the CPU or GPU. You should test your PC to make sure that the CPU and GPU are not overheating anymore.

Reducing Power Load on PSUs

The fifth step you can take is to reduce the power load on the PSU. Power load is the amount of electrical power used by your PC. Too high a power load can cause the PSU to overheat because the PSU has to work harder to provide enough power for all components. Too high a power load can also cause the PSU to be unstable and can damage other components.

To reduce the power load on the PSU, you must know how much electrical power is needed by your PC. You can use some software that can calculate the power load of your PC, such as PSU Calculator, Outervision, or Cooler Master. This software can display the power load of your PC based on the specifications of the components you enter. You should also add a safety margin of about 20-30% of your PC’s power load so that the PSU can work optimally.

Once you know the power load of your PC, you should compare it to the electrical power that your PSU can provide. You can check the electrical power of your PSU by looking at the label on the back or side of the PSU. These labels typically display information about the make, model, and specifications of the PSU, including the maximum electrical power it can provide. If your PC’s power load exceeds your PSU’s electrical power, then you should reduce your PC’s power load or replace your PSU with a larger one.

There are several ways to reduce the power load of your PC, namely:

• Reduce the number of components connected to a PC, such as hard disks, optical drives, sound cards, network cards, or USB devices. You can remove components you don’t use, or replace them with more power-efficient ones.
• Reduce graphics settings for heavy games or applications, such as resolution, quality, or effects. You can adjust the graphics settings according to the capabilities of your GPU so that the GPU does not work too hard and consumes a lot of electrical power.
• Enable power-saving features on your PC, such as power plan, sleep mode, or hibernate mode. You can set this feature through the Control Panel, Power Options, or BIOS. This feature can reduce the electrical power used by the PC when idle or inactive.
• Use software that can optimize PC performance, such as CCleaner, Advanced SystemCare, or Razer Cortex. This software can clean junk files, repair the registry, remove malware, or increase FPS in games. This software can make your PC lighter and faster and can reduce the power load on the PSU.

Replacing PSUs with Better and Appropriate ones

The sixth and final step you can take is to replace the PSU with a better and more appropriate one. If the previous steps did not resolve PSU overheating, or if your PSU is too old or damaged, then you should replace your PSU with a new one. Replacing the PSU is one of the most effective ways to deal with PSU overheating and prevent damage to PC components.

To replace a PSU with a more suitable one, you should choose a PSU that has good quality, electrical power, and compatibility. You can use the following criteria to choose the right PSU for your PC:

• Quality: You should choose a PSU that has good quality, that is, a PSU that has a certificate of efficiency, circuit protection, modular cables, quality fans, and a long warranty. A quality PSU can provide stable, safe, and economical electrical power. You can check the quality of the PSU by looking at the brand, review, or rating of the PSU.
• Power: You should choose a PSU that has enough electrical power for your PC, that is, a PSU that can provide electrical power greater than the power load of your PC. You can use software that can calculate the power load of your PC, as explained earlier. You should also add a safety margin of about 20-30% of your PC’s power load so that the PSU can work optimally.
• Compatibility: You should choose a PSU that has good compatibility with your PC, that is, a PSU that has the size, shape, and connector that fits the case, motherboard, and other components. You can check PSU compatibility by looking at the specifications, manuals, or pictures of the PSU. You should also make sure that the PSU you choose supports ATX, EPS, or SFX standards, depending on your PC type.

Once you have chosen a better and suitable PSU, you should replace your PSU with a new one. You can follow the same steps as step three, which is to replace a damaged or noisy PSU fan. You must be careful and careful when replacing the PSU so that no errors or damage occur. You should also test your PC after replacing the PSU, to make sure that all components are working properly and there are no problems.
