One of the most frequent error messages that can show up when a Windows desktop or laptop is first starting up is the CPU fan error. Usually, the alert comes on after a computer has overheated and shut down. It could occur if there is insufficient cooling of the hardware by the fan or fans.
The forced shutdown and CPU error message are annoying, but they also mean the computer’s security measures are functioning as intended. Hardware components may sustain irreversible damage if the computer overheats and the fans stop functioning.
As with the error messages that follow, there are ways to identify the source of the overheating and how to resolve it.
How the CPU Fan Issue Shows Up
The CPU fan error typically shows up during the startup or bootup phase of a Windows computer; it does not show up during normal Windows operation. Typically, the error message text looks like one of these:
“Error: CPU Fan Has Failed!”
“CPU Fan Error”
What Causes CPU Fan Errors?
Incorrect settings, external factors that cause the computer to overheat and force the fan to run at unusually high speeds, or physical damage to the fan are the usual causes of a CPU fan error on startup. CPU fan errors may arise from dust or other objects blocking the device’s air vents.
Ways to Resolve a CPU Fan Error
Because software and hardware issues can also result in CPU fan errors, the solutions are equally diverse and entail examining particular configurations as well as the internal CPU fan.
To prevent error messages and CPU overheating, heed these tips.
Transfer your computer. Regardless of how hard the fan is working, leaving your computer in a hot or sunny spot can lead to overheating and shutdown. A cooler room might be a good place for your computer, and avoid leaving it in the sun all day.
Stop overclocking. A consequence of overclocking is a dramatic increase in system heat that the default fans can’t manage. In addition to causing frequent shutdowns and overheating errors, overheating can harm circuits.
Maintain the coolness of your computer. Removing the brush from your vacuum cleaner and using it at maximum power to remove any dust and debris is the simplest way to clean the air vents. As an alternative, blast out the dust with an airgun or canned air.
The CPU fans should be cleaned. You must unplug your computer from the power source, turn it off, and open the case in order to complete this step. Once it’s open, you can use canned air or an air gun to clean the interior and get rid of dust.Avoid misting any kind of cleaning solution on any part of the machine since it can cause major harm to different parts.Opening certain devices—like the Microsoft Surface line of products—may void the warranty or result in irreversible damage. If you’re unsure, consult the official support manual for your device or give customer service a call.
Examine the fan on your CPU. Physically inspect your device’s fans to make sure they haven’t come loose or fallen out of place while your computer is open. You should be able to use glue or a screwdriver to secure your fans back into position, depending on the model of your fan.A complete turn off and disconnect from all power sources are prerequisites for inspecting anything inside an electrical device. When you turn off your computer, don’t forget to select Shut Down instead of Sleep.
Check your CPU fan’s location. Assuming you installed the CPU fan yourself, make sure it is in the proper location. It ought to have been connected to the motherboard’s CPU header. The fan may run when the computer is on if it is connected somewhere else, but it will not effectively cool the CPU, which is its main function.Probably labeled “CPU Fan,” the CPU header is still easily identifiable thanks to its three holes for the fan’s three-pronged plug.
Examine a different CPU fan header. Try plugging the fan into a different slot on your motherboard if it has multiple CPU fan headers. Sometimes, doing this resolves the CPU fan error.
Check the CPU fan’s settings in BIOS. Make sure everything is working properly by using it to troubleshoot technical issues.Select Advanced Settings > Hardware Monitor > CPU Fan after starting BIOS. Turn on the fan and the active heat sink, and turn off the fan and the passive heat sink. Save your edits, then close the BIOS.When you see the initial CPU error message, you will typically be prompted to press F1. When this message appears, pressing F1 will also launch BIOS.
Modify the BIOS configuration. This modification to the BIOS setting in step No. 8 can get your device up and running and avoid the CPU fan error message if you can see your CPU fan operating correctly and you’re certain your computer isn’t overheating or running too hot.Open the BIOS and choose Monitor > Fan Speed Monitor > N/A > Ignore > Exit > Save Changes to accomplish this.This setting may hinder your computer’s capacity to identify CPU fans and result in future overheating issues. We advise against it unless you are certain that your laptop’s CPU fan is operating and you are able to take its temperature.
Change the fan on the CPU. You may need to replace your fan if none of the aforementioned fixes work. The warranty on your computer might pay for the fan repair. The fan may come with a separate warranty that you can use to receive a free or heavily discounted replacement part if you bought it separately.The Top 2024 Laptop Cooling Pads
How can I quiet my computer fan?In order to quiet a noisy computer fan, you should first clean the fans, look for high-processor programs in the Task Manager, and take precautions to prevent overheating of the computer.
How can I adjust the speed of my CPU fan?Apps from the manufacturer or the BIOS on your computer can regulate the speed of your CPU fan. Avoid setting the fan speed to ‘0’ since it could lead to CPU overheating.
When my CPU is still spinning, why do I keep getting a fan error?If the fan is operating and you are still receiving errors, either the fan is malfunctioning or your computer isn’t registering the fix for the error.
