CPU Fan Error: Mitigate It With Simple Hack

While using a system, you will encounter various types of issue or error on a daily basis. Those errors can be associated with either software issue or hardware issue. Now, the CPU fan error is one of such few error messages which are connected with both software and hardware issues.

The fan error usually appears in a system while it is booting up. Most of the time, this error message won’t allow the user to enter in the desktop screen. But the users can avoid the warning message by pressing the Esc key.

This will let the user enter into the desktop screen, but overheat the system as well as the CPU. This overheating issue can affect the performance of other components and may damage them as well.

Now, if you want to know how to fix CPU fan error then follow this article to the end. This is because we have provided every possible solution to this error here. But before entering into the solution section we will suggest you have a look at the main cause of this error. 

Major Cause of the CPU Fan Error on the Boot

In a system, there are various types of problematic factors that can trigger this error message. We have explained the prime problematic factors in the section below.

This will help you to understand the error in a better way and for that reason, you can use the solutions more effectively. Now, let’s have a look at them. 

  1. Inappropriately set fans information in BIOS window- While setting up the system, for the first time, many users set wrong values for the fan settings in the BIOS window.
  2. The CPU Fan running too slowly because of dust or the quality of the Fan-  After a period of time, dust or other materials start accumulating on the fan blades and thus, the fan starts spinning slowly. 
  3. Apart from that, if you are using a low-speed fan for cooling the CPU then the CPU fan error can appear.
  4. The CPU fan is connected in the wrong connection port- If you configure the system on your own, then you may get confused among the connection ports.
  5. The CPU fan is damaged or broken- In certain conditions, the CPU fan can get damaged because of overheating issue or physical problem.

Now, if you have analyzed all the possible causes of this error then let’s have a look at its solution. 

4 Ways to Resolve the CPU Fan Error

There are various ways by which a user can remove this error from their system. But, they need to apply the solutions properly in order to get a positive result.

In this section, we have provided the best ways to eliminate this error. Have a look at them and try to execute those solutions as instructed.

Modify the CPU Fan Settings in the BIOS

Most of the time, this error appear in a system when there is a misconfiguration in the core fan settings. Now, to rectify those settings the user needs to enter into the BIOS window. Thus, follow the given steps.

  1. Reboot the system and when the black window with internal information or brand logo appears, press F2, F12 or Del button. The BIOS window will come up on the screen.
  2. There you need to tap on the Power tab and then highlight the Hardware Monitor option. This option will be on a pop-up list or menu. 
  3. In the Hardware Monitor window, you will get the CPU FAN SPEED option. Select that option and change it into IGNORED. 
  4. Then, click on the CHASSIS FAN SPEED option and set it into N/A mode. 
  5. After that, look for the POWER FAN SPEED option and modify it into IGNORED.

Now, press the F10 button in order to save all the changes and exit from BIOS Setting window. Once you are out of that window, the system will reboot again. 

At that moment you need to check whether the CPU fan error on boot is removed or not. 

Check the Speed of the CPU Fan

In certain situations, this error message may occur because of the Fan speed. To check it out you need to turn on the system and verify whether the CPU fan has proper workability or not.

If the speed of the CPU fan is unbearably slowly then you need to check the components that are responsible for its slowing down. Then, remove those factors carefully. 

But, while doing that task you need to make sure that the CPU fan doesn’t get damaged or hit by something. After completing that task, check weather the CPU fan speed error detected on the system is not. 

Reconnect the CPU Fan Correctly

In a motherboard, the user would find various types of connection ports. These allow a user to connect multiple types of fans at the same time. But there are also other connection ports in the motherboard which look similar to the CPU fans ports. 

Now, it is quite possible that while connecting the CPU fans, you had inserted its cable into the wrong connecting port. And that incorrect connection is creating the CPU fan error in the system. 

To fix that problem, you need to open up the system and check every fan connection. If you find out any type of cross-connection then unplug them and put them into the correct port. 

Change the CUP Fan

However, if none of the given solutions work out for you then it might be possible that the CPU fan connected in the system is faulty or damaged. To verify that, remove the CPU fan from your system and connect into another system. 

Now, if you get the same CPU fan error on boot then it clarifies that fan is damaged. You need to replace it with a new one in order to get rid of this error message.
