The CPU fan error for the CPU fan issue is one of the standard error messages that may appear when starting a Windows laptop or desktop. The message is typically triggered when a system has shut itself down because of overheating. This can happen when it is the case that the fans (or fans) cannot adequately cool the computer.
While it is frustrating, The CPU error message and the shutdown are forced to signal the computer’s security measures are functioning correctly. If the fans aren’t operating correctly and the laptop is constantly overheating the computer, it could cause permanent damage to any number of parts of the hardware.
There are several ways to verify the root of overheating and the following errors and solutions to correct them.

Cpu fan error

CPUs produce a lot of heat when they’re in operation. Even when the CPU is not working at a high level, it will require constant cooling. To do this, there are specially designed CPU fans that remain in operation to help disperse excess heat away from your processor if the fans cease to function and notice that the CPU temperature rises steadily.
If the temperature is higher than the limit of the design, The computer may fail to boot or shut down without warning. In this way, you’ll see several dedicated 3rd party CPU cooling systems designed to keep temperature levels at low levels.
But, many users are faced with problems with CPU fans, which indicate problems with the fans or the system that controls CPU fans. Today, we’ll examine the CPU fan errors and determine what causes them and why it is a problem on a PC. We will also give some solutions if you’re having the same trouble, to eliminate it as quickly as possible.

What Is CPU Fan Error?

As the name implies, the CPU fan issue typically occurs when there are problems in your CPU’s fan. It’s almost impossible to operate an operating system if your CPU fans aren’t functioning correctly. Even basic applications such as Discord and Google Chrome will utilize CPU at a speed that can rise in temperature beyond the limit of its design.
Like you may have experienced previously, this triggers an instant system crash that restarts the computer. If your computer isn’t rebooted, it will freeze after some point, and you’ll have to force restart the system to be able to get it back up and running. This is sure to cause loss of information. Regular system reboots may create bad sectors in your drive. They can eventually cause the industry to be damaged and cause irreparable loss of data.

What Causes CPU Fan Errors?

There are several Reasons that causes CPU Fan Error some of them are as under:


How to Fix a CPU Fan Error

If you’re also suffering from the problem of a CPU fan, fret not. In most cases, you can get the issue fixed by following one or two of the suggestions discussed in this article. We can guarantee that you’ll be able to get rid of the error caused by the CPU fan after this guide. But, be sure to be attentive to each step and the suggested solutions to eliminate the issue permanently.

Since problems with CPU fans could be caused by hardware and software problems, the solutions to the issues are equally diverse and require checking specific settings and the internal CPU fan.
Use these guidelines to avoid CPU overheating or errors.

1. Change Computer’s Location. The first thing you must try is changing the cabinet’s location. A wrong installation will almost definitely result in a lack of airflow, which can result in higher temperatures for your CPU. If you reside in a hotter region, it is essential to ensure that your PC is not placed directly in the sun, as this can cause a temperature rise.
In these situations, it is likely that the CPU temperature will eventually surpass the design limits, even if the CPU fans function well. Create an area over your desk and then move the cabinet up to ensure plenty of airflow. The room’s overall temperature also has a significant impact on this particular situation.
If you’re experiencing this issue with laptops, you must look into purchasing a cooling pad that is ideal for notebooks. It comes with external fans that boost the amount of airflow inside your system and lower your processor’s temperatures.

2. Check Overclocking Parameters. Many hefty users tend to overclock their CPUs to achieve the highest performance when playing games with high demands. One of the most frequent adverse effects of overclocking your CPU is the increased temperature caused by the increased power consumption and higher clock speeds. If you’re also experiencing the problem with your CPU’s fan after overclocking your CPU, you’ll need to run your CPU’s in the default settings.
If your motherboard or CPU is capable of overclocking, you’ll see your overclocking status in the BIOS. When you boot your system, press the DEL key and then check the overclocking parameters in the BIOS settings. You can download AMD Ryzen Master application software for AMD processors to check the status then.
If you want to increase the speed of your CPU to achieve the best performance, you’ll need to install an AIO instead of the standard CPU cooler. It is also possible to invest in a custom-designed water cooling loop if you want to get even better-overclocking performance from your CPU.

3. Take Care of Residue Dust. If you don’t wash your computer cabinet regularly, you are likely to see an abundance of dust collecting over your computer fan. As we’ve mentioned before that dust can impede airflow, causing the fans to run slower even though they’re running at full speed.
Cleaning your desk cabinet is not a difficult task. The most effective method is to utilize an efficient vacuum cleaner that can remove all dust with a single blast. If you don’t own a vacuum cleaner, you can use an air blower to remove the dust. The air pressure from the blower will quickly move dust from the cooler and CPU fan to solve your problem.

4. Check CPU Cooler. If you’re still having trouble with the issue, it could be time to examine the CPU cooler. Standard CPU coolers are adequate for everyday use and gaming most of the time. But, if your cooler isn’t operating optimally, it will be afflicted having a CPU fan issue. The CPU cooler typically consists of one fan when using a standard cooler. An external cooler may come with dedicated fins and pipes made of metal to boost the heat exchange rate.

It is essential to examine the CPU cooler inside the case of a similar topic and check that it’s functioning correctly. Another critical aspect, in this instance it will be the temperature of the paste. This paste gets sprayed between the CPU and the cooler to allow the cooler to work efficiently. When the paste has dry, you’ll need to clean your CPU before applying it again by hand.

5. Check CPU Cooler Direction. If you’ve manually installed an external CPU cooler, ensure it’s properly installed. On the tremendous fan, an arrow shows the direction of airflow. Ensuring the correct CPU fans push hot air away from the cabinet is essential. While you’re at it, be sure to check that the cabinet’s fans are correctly installed and functioning as exhaust fans or intake fans, depending on their place of installation.

A CPU cooling fan or fans must connect to your motherboard for accurate control. The motherboard controls the fan’s speed following the temperature of your CPU. So, ensure you secure the coolers for your CPU to your motherboard. Also, you can get direct control of the fan using specific software after the fans have been attached to the motherboard.

6. Consider An Alternate CPU Fan Header. Sometimes, a specific part of the fan’s header on your motherboard may also be the reason behind the CPU fan issue. If the title isn’t functioning, the fan will not receive any power, which results in an active fan. As the header is not working and the motherboard cannot detect the fan. So, you won’t be capable of identifying the problem using any control software.

Connect the fan to another connector on your motherboard to fix this issue. If you have several cabinet fans connected to your motherboard, you could test unplugging a few units to see that the problem is due to the header. If you can’t join the fan with your motherboard anymore, it is possible to purchase an external fan controller for your PC. They run on the PSU and can provide external control of the fan via the remote or software.

7. Check BIOS Settings. If all the solutions above have not worked to fix the issue with the CPU fan for you, the problem lies in the BIOS settings.

Here’s how you can determine the status of the fan in BIOS:

  • Switch off the computer.
  • Now, you can restart your system. When your system starts to boot up, continue pressing”DEL” to enter BIOS “DEL” key to enter BIOS. The shortcut key could be different based on your motherboard’s manufacturer.
  • Once you’re in the BIOS, then go in”Advanced Settings,” then “Advanced Settings”, and look for the “Hardware monitor” section.
  • Here, you can see all settings related to the hardware you have installed on your PC.
  • Under the “Hardware Monitor” section, choose”Hardware Monitor”, then select the “CPU Fan” option. This section is specifically designed for setting the CPU Fan.
  • Within”CPU Fan” in the “CPU Fan” section, select”Active Heat Sink” and “Active Heat Sink” and “Fan Duct with Fan” options.
  • If you have the “Passive Heat Sink” and “Fan Duct without Fan” options are turned on, switch off the possibilities.
  • Press F10 to save your configurations. Your system will start to reboot generally after that.

8. Replace CPU Cooler. We also suggest replacing the CPU fan. Most of the time, standard CPU coolers can’t handle the load of high-volume usage, and the ones that come with them wear their energy quickly. We strongly recommend purchasing a top-of-the-line third-party CPU cooler to provide the highest performance on your computer. If you’re doing overclocking, you’ll need to invest more in an AIO or a custom liquid cooling loop based on your requirements.

In terms of installing the cooler, you’ll find all the necessary information in the package. This thermal paste could be applied before applying it to the heatsink, or you’ll find the thermal paste in the cooler. If you’re unsure about the application of thermal paste or the installation of a CPU cooler, it is recommended to talk to a professional for help getting the task completed.

9. Verify your CPU’s position. If you’ve installed the CPU fan yourself, make sure it’s in the right place. It must connect to the CPU’s header located on the motherboard. If you’ve connected it to another device, the fan could start while the PC is powered on, but it will not sufficiently cool the CPU; that’s its primary purpose.


A problem with the CPU’s fan is typically an indication of poor CPU performance due to the high-temperature levels. If the CPU’s fan isn’t functioning as it ought to, you’ll find your CPU performing poorly by many times. Additionally, it causes frequent system freezes as well as stutters. You may also experience system restarts when the temperatures aren’t in check.

Through our tutorial, we’ve given you several options for taking care of the problem with the CPU fan. If you adhere to each of our recommendations carefully, you will solve the problem independently. If none of the solutions mentioned above worked for you, contact us via the comments section to discuss the issue further.
