How to Fix a CPU Fan Error?
A CPU fan error message can pop up for many reasons, such as overheating, power issues, cooling setbacks, or components that aren't working correctly.
CPU fans may not work because of hardware or system problems on your device. If there is a fan speed error or generic CPU fan errors, try checking the air vents to see if the motherboard is getting enough exposure.
Chances are your system may not work properly due to dust build-up and poor air supply linked to malfunctioning fans.
You can avoid permanent damage by checking your advanced settings, motherboard efficiency, or excess load from existing software.
Whether your CPU fan speed is low or a CPU fan error displays, there are several ways to ensure your fan is working and all connected hardware functions smoothly for your device.
8 Ways to Fix a CPU Fan Error
Whatever the error message, the systems, monitor, and software settings ensure your CPU fan components stay clear of overheating and work through ideal cooling rates.
Access the CPU fan
Once your computer is open, check the fans to ensure the fan is working right and no components are out of place. See how it is installed and plugged in to avoid changing hardware or blaming your software unnecessarily.
Remember to disable all power sources to avoid further affecting and lowering your CPU fan speed.
Verify the location of your CPU fans
Remember, CPU fan errors can often be resolved by verifying whether the CPU head is correctly connected to the motherboard. If the connection appears elsewhere, your windows laptop, be it ASUS or any other company; might be forced to work with a cooler system that may not work correctly.
Look for a label showing the CPU header as the CPU fan. This may help you detect the location correctly and regain fan control.
Double-check the settings of your CPU fan in the BIOS
Troubleshooting issues through the exit bios may help you catch any poorly connected hardware during startup and replace it with properly plugged and installed hardware.
Once you access BIOS, head to advanced settings, followed by the hardware monitor and then the CPU fan. You can enable the active heat sink and disable the passive heat sink to prevent overheating in the CPU or monitor section.
Look out for an error message stating a problem with the CPU. Once visible, click on F1 to open the BIOS.
Keep your device cooler
Try detaching the brush from the vacuum cleaner and cleaning the air vents using its maximum power capacity. This helps capture dust and save your device from overheating, leaving it cooler than the average, unmaintained system.
Dust off the dirt from the CPU fans
Turn your computer off to stop the fan from spinning. Whether a laptop or desktop, properly open the case and detect any signs of dust or air-deprived sections.
Cleaning the excess dust could improve your fan's RPM and make your computer function well within the ideal fan speed low limit.
Eliminate overclocking
If your diagnosis indicates the "CPU fan speed low," stop overclocking to eliminate episodes of overheating. Such extra heat could ruin your computer and cause fan spinning, startup, or a cooler error message.
If you face boot problems or your computer has malfunctioning fans not working correctly, these settings could ensure your motherboard is allowed to function at full capacity.
Shift the position of your computer
Irrespective of your fan's RPM, the cooler's working, or BIOS settings, leaving your computer exposed to excess sunlight or heating devices can spoil the fan and lead to more significant dust build-up.
Tweak BIOS settings
If you believe your computer's boot process and air pump are working fine, follow the 3rd point and resolve the annoying CPU fan error message.
Once you're in the BIOS, access the fan speed monitor section under the monitor tab and select N/A. Further on, choose ignore and safely exit by savings the settings.
Use a new CPU fan header
Consider replacing the CPU fan header if constant CPU fan errors make you struggle with poor cooler functioning or motherboard problems. Simply solve the error by fixing the CPU fan header onto an alternative slot. This may put a stop to any CPU fan error message you receive.
Overheating may also stop, and you can detect plugged fans that your computer can't effectively control anymore.
Ways To Solve Overheating Issues Caused Due To The CPU Fan Error Message
Here are some ways to resolve a CPU fan error and save your CPU from malfunctioning:
External fans or heat-removing devices can improve the output of your CPU fan. Using air conditioners or stand fans can help your computer regain fan control and enhance the per minute rotations rather than having to replace parts.
Whether or not your CPU is always connected, do not ignore notifications of over usage. Relieve your motherboard of extra load by shutting not-in-use applications.
Turning your device off for a while appears to give your motherboard and fans rest, saving you the hassle of a BIOS change and helping to reestablish your fan's best-performing RPM.
If the fan errors aren't detected on boot, open the computer and check whether the fan is connected to the right connector. If not, the CPU fan error may arise again since it isn't being controlled by the BIOS.
Verdict
If a CPU fan error arises during the POST process, try checking the RPM in BIOS interface to look for unintended changes you may have made. Fixing your CPU fan error becomes much easier when readjusting such settings to their default value.
You can even use the thermal paste to take care of this error and avoid worrying about whether other connected hardware is doing its job. On the other hand, if you have had to replace or readjust your CPU fan or the fan RPM, fix it by properly reconnecting existing connections.
Make sure to use high-quality thermal paste, which appears to improve your CPU fan's heat insulating abilities properly.
