CPU Fan Error

CPU Fan Error ( Everything You Need To Know )

The Central Processing Unit (CPU) is one of the most important components of a computer. It carries out a lot of calculations (among other functions) and therefore also generates heat when it is operating. The heat generated should also be dissipated well enough so that overheating is avoided.

CPUs come with CPU fans that run and cool the component and ensure that heat is dissipated. However, people may face issues and the message of “CPU fan error” often in cases of overheating.

CPU Fan Error

The error message “CPU fan error” can be found on the window desktops as well as the laptops. It occurs due to overheating and usually shows on the screen when the computer shuts off automatically in the aftermath of heating issues.

The fan is not able to cool the CPU in such conditions and the temperature of the CPU may rise above its design limit. When such overheating occurs, the computer or the laptop will reboot itself or will simply crash without providing any notification.

Sometimes the computer may freeze at a certain point due to overheating and the user will have to reboot it for making it functional again. Higher than permitted heat can damage the components of a computer and can also cause accidents.

There are also certain systems available for CPU cooling that are provided by third parties and businesses. These systems also help in controlling the CPU temperature. An excessive number of reboots can cause certain problems.

For instance, a frequent reboot of the system will result in the presence of bad sectors on a hard drive. It may lead to the corruption of the hard drive and may also lead to irreversible data loss.

If the computer is automatically turning off due to overheating, it shows that the safeguards given on the computer are functioning properly. A grave problem can occur when the safeguards do not work and the computer continues to get overheated. It may result in damage to components and other issues. A CPU error message and the text may appear as follows.

· The error message says “CPU Fan Error”.

· The error message says “Error: CPU Fan Has Failed”

Causes of CPU Fan Error

There can be multiple reasons and issues due to which a CPU fails to work and operate at an optimal level. Some of these reasons are given below.

  • CPU fan may fail due to physical damage, in the majority of cases. The damage may occur to the blades of the fan, which results in reduced a
  • Damage to the cables may also reduce or impede the power supply and therefore cause the failure of the CPU.
  • Inaccurate BIOS settings may cause the failure. It may affect the software that is controlling the fan, for the laptops.
  • The temperature of the system may also increase due to the accumulation of dirt and dust within a computer system. It will impact the heat exchange rate adversely and will result in the rise of temperature.
  • If the computer does not have enough free space around it, the heat may build up and cause heat overheating. It occurs due to the blockage of airflow, which also affects the performance of the CPU fans adversely.

How do I fix a CPU fan error?

Both “software”, as well as “hardware” related problems, can result in an error in the functioning and performance of the CPU fan. The actual solution of the problem will depend on the source of it. Below are certain measures that can be used to resolve the issue and to make a computer functional again when it faces the CPU overheating issue.

Moving the computer and adjusting its placement

if a computer or laptop is been used or is kept in an area where there is a lot of sunshine and heat, it may result in overheating rather easily. Even if the fan is functioning at an appropriate level, it will not be able to dissipate the high heat that is being generated. In such cases, the computer should be moved to a cooler location. You must also ensure that the computer is never kept in a place where sunlight falls directly.

Avoid overclocking

overclocking is the practice of using the processor of a computer at specifications higher than what has been rated or recommended by the manufacturer. Users should avoid overclocking as it may result in much greater heat and issues including overheating.

Such issues may cause damage to the components of a personal computer and may result in messages such as the “CPU fan failure” error message. Overclocking may also damage the inbuilt circuits of a computer and cause frequent automatic shutdowns.

Ensure that the computer remains cool

a computer can remain cool when it avoids sunlight and when there is no accumulation of debris, dirt, and dust in it. You can use your vacuum cleaner (after removing the brush) for cleaning your computer. The machine will be able to suck all the dust. Alternatively, you can use an air gun or blower so that the dust and dirt are blasted out of the machine.

Regularly clean the fans of the CPU

When you have to clean the fans of the computer, you need to first unplug the computer from its main power source. Next, you can open up the case of the computer. You can use a computer cleaning brush for cleaning and removing all the dust accumulated inside the computer and accumulated on/near the fans.

Alternatively, you can do the cleaning by using canned air or an air gun. However, avoid using the cleaning agents and the sprays on the internal components of the computer as these components may undergo damage when exposed to harmful chemicals.

Inspect the CPU fan

damage to the CPU fan is a cause of its dysfunctionality in the majority of cases. Therefore, you need to physically inspect the fan of the device and see whether any part is loose or has fallen out of its designated place. You can use glue or a screwdriver for putting the part back to its original position.

Inspect the location of the CPU fan

those new to computer upkeep and maintenance may install the fan of the CPU at an inaccurate location. The fan has to be connected directly to the header of the CPU, which lies on the motherboard. If the CPU fan is placed and connected anywhere else, the fan may still run but may not provide any cooling to the CPU.

Check BIOS Settings

you may also need to troubleshoot any technology and software issues with the PC. With the fan issues, you have to open and check the BIOS settings. You have to follow the below-given pathway for checking the fan error issue on your PC.

Advanced settings-> hardware monitor->CPU fan

At this location and point, you have to enable the “active heatsink” and the “fan duct with fan” options. You should disable “passive heat sink” and “fan duct without fan“. Now save the changes you made and then exit the BIOS settings.

Change Computer’s BIOS settings

if you are sure that your computer is not overheating and the message that you see of CPU fan error has no real significance, you can simply bypass the previous step. In such a scenario where you get a wrong update of CPU fan error even when the device is working fine without any overheating, you need to follow the below-given pathway.

BIOS-Monitor->Fan Speed Monitor-> N/A-Ignore-Exit- Save Changes

Replace Computer CPU cooling fan

in case the fan is broken and damaged, it needs to be replaced. Sometimes there may be warranty coverage provided for your fan issues and the damage. The new fans may also come with a separate warranty of their own.

How do I get rid of the CPU fan error on my Asus?

The users of Asus computers may see the message “CPU FAN error“. It means that the system and the computer cannot detect the CPU fan. If you see this message, you can follow the below-given tips.

  • Ensure that the file is installed accurately and is screwed tightly with the motherboard.
  • The fan cable should also be installed correctly with the connector.
  • If a replacement fan is installed and if it has a slow or lesser revolution speed, the system may fail to detect.
  • If you are sure that the CPU fan error message is not coming due to any damage or any other kind of issue, you can use the below-given path.

Monitor-> CPU fan speed->Ignore

However, you should ensure that the settings are the latest. You have to update the settings of the BIOS to the most recent and latest version. If you cannot find a solution, you can contact the customer care of the company to get a resolution.

What will happen if the CPU fan fails?

If the CPU fan fails or is dead and the computer continues to operate, it may result in overheating. The computers do have a safeguard, which ensures that they shut down automatically if overheating occurs.

If the safeguards are not functioning, the CPU gets ignited due to heat and the computer may be destroyed to an extent that it cannot be repaired. That is why it becomes important to check the issue if you get the “fan fail” message and error. In some cases, the error may be rectified while in others the CPU fan will require a replacement.

Conclusion

It is important to look after your computer and to ensure that it is updated. You should also inspect your computer for speed, dust, dirt, and other issues from time to time and ensure that the machine is clean and free of errors. It is also important to act soon on the “CPU fan fail” message as the situation may turn to be worse if it is neglected.
