Motherboard Temperature – Causes and Fixes

Motherboard temperature is critical to its overall performance and health. A motherboard is hardware that links all of the other components of a computer. all the components including CPU, RAM, GPU, hard disc, are mounted here. It is responsible for all of the operations required to perform word processing, online surfing, gaming, streaming, and other operations.

Internal components of any system (processors, graphics cards, hard drives, and so on) can easily go down when overheated. The better the performance of the system needed, the more components are loaded, resulting in fairly high-temperature values. Overheating of computer components happens occasionally, which might have unpleasant outcomes.motherboard temperature over 100

Up to a specific threshold temperature the electrical conductivity of the semiconductors on the motherboard increases. Beyond that temperature, there is a significant loss in electrical conductivity. Consequently, the communication level between the components mounted on the motherboard decreases resulting in lower performance of the system. Hence, maintaining motherboard temperature below this threshold can help you get the most out of your system and avoid any harm.    

Motherboard Temperature Monitoring

There are two simple techniques for motherboard temperature monitoring. Thermal cameras are another option, although they are more costly.

  • Basic Input Output System (BIOS):

You may also monitor the temperature of your motherboard from the BIOS of your computer.  To access the BIOS setup, hit the “F1” or “Delete” key during the starting process. Using your arrow buttons navigate  “PC Health” or “Monitor”.  The temperature of the motherboard will be shown there. But you’ll have to restart your computer to get into BIOS.

  • Third-Party Applications: 

There are few software solutions available to check and monitor the motherboard temperature. Some motherboard makers provide their hardware temperature monitoring tools, however, it is only compatible with their models. Some of the famous software are:

The best tool for monitoring motherboard temperature is Open Hardware Monitor. It’s open-source and free with all the bells and whistles. The tool is compatible with Intel and AMD processors, as well as Windows and Linux OS. It offers a user-friendly UI. You may also simply expand the segments and sub to see additional details. This way, you won’t be flooded with too much information.

HWMonitor displays information about the hardware, such as voltages, fan speeds, and temperatures. It is compatible with both Chipset and Intel devices.  It is only compatible with Windows OS and works on Windows 10. It is available in both free and paid versions, although the free version is sufficient for determining motherboard temperature. 

Safe Motherboard Temperature

The highest temperature that a motherboard should be allowed to attain is 85 degrees Celsius. A temperature of more than 85 degrees Celsius is too high and can harm your computer’s components. However, when monitoring motherboard temperature, you should keep an eye on three separate temperature ranges.

  • Motherboard temperature when idle:

The average temperature of the motherboard must be within 20 and 40 Centigrade while the computer is idle, that is, when nobody is using it or when the computer starts up. Since the CPU does have a separate heatsink that aids in cooling, the temperature of the CPU can be greater than the temperature of the motherboard, but it should never exceed 80 degrees.

  • Motherboard temperature when slightly loaded:

If you are just surfing the web or watching Youtube, the temperature on your motherboard should be between 40 and 60 degrees Celsius. These are quite safe temperatures, indicating that your board isn’t working too hard. When the temperature of your motherboard surpasses 60 centigrade, this means that your motherboard is heating up even though you aren’t doing anything strenuous. It’s most likely that your device’s fans aren’t working correctly and need to be serviced in this situation.

  • Motherboard temperature while gaming:

When you’re gaming, all of your computer’s components, such as graphics cards and RAM, are working hard to provide the best possible performance, which creates additional heat. Heat sinks help to lower the temperature, however, they fail when the temperature rises over a certain point. As a result, the temperature may rise to 75 to 80 degrees in this instance. Under such conditions, you should not use your device for lengthy periods because it is extremely harmful to your system’s functionality. The use of your motherboard in such harsh temperatures might cause lasting harm, and you may need to replace it. So, for this sort of usage, take appropriate breaks and keep sufficient ventilation.

How To Check & Lower Motherboard Temperature?

A computer transfers data between numerous components such as the CPU, memory, hard disc, and video card while it executes tasks. All of this information passes via the motherboard, and excessive motherboard temperature can lead your computer to become inefficient and break in unanticipated ways. So, maintaining the optimal temperature is mandatory. Here are the following methods you can use to lower the motherboard temperature of your device. 

  1. Clean the motherboard:

Dust is the most prevalent cause of overheating on motherboards. It can also clog the heat sink, preventing fresh air from reaching the motherboard and causing it to overheat. So, have a look inside your computer case and see what’s going on. In this scenario, detach your computer from the power source and clean the motherboard using a brush and Liquid cleaner, which is widely available in the market. 

  1. Motherboard Temperature Check fans:

Examine the fans inside of the CPU case to see if they are operating or not. Dust accumulates on the fans from time to time, causing friction and lowering their speeds. As a result, clean the fans to ensure that the CPU case has adequate airflow. 

If any of these is not operating, replace them immediately to avoid harm. If the fan of the power supply stops operating, the entire power supply will have to be replaced. To handle the excessive motherboard heat, fans must pull cold air.

If your fans are functioning correctly, the next important thing to look at is their placement. One fan in the front of the computer and one at the rear would be good. 

  1. Use motherboard standoffs:

Electrical contact with the PC casing is prevented by standoffs. They are usually included in the system case, while some manufacturers also include them with the motherboards. They are, in any case, a vital component. If you don’t use it, the System components may become damaged or the motherboard temperature might rise.

  1. Close background apps:

When you’re not using an app, don’t leave it running in the background since it increases the burden on your memory, requiring more power to perform other activities, which raises the device’s temperature.

  1. Apply thermal paste:

Thermal Paste is used between CPU and sinks to increase heat transfer.  In most circumstances, reapplying this paste will fix the overheating problem.  However, if you are hesitant of doing this on your own, it is advisable to seek the assistance of a professional.

  1. Maintain proper ventilation:

You can protect your motherboard from heating up by ensuring proper ventilation and airflow.  Your computer system should not be tucked away in a corner or covered with a towel. Your PC must have enough breathing room. If there isn’t enough air surrounding your computer, the cooler will struggle to circulate air. As a result, the motherboard becomes overheated.

Additionally, ensure that the configuration of your computer components allows for enough ventilation within the case. When extracting and pushing air from your computer, the fans should not come into contact with any blockages. Also, make sure that no connections or wires are obstructing ventilation within your computer.
