What Is CPU Fan Error? How To Fix It?

The CPU Fan Error is a popular error message when setting up a Windows desktop PC or laptop. The message usually comes after a PC has shut down due to excessive heat. This occurs when the fan (or fans) is unable to effectively cool the hardware.

When setting up a Windows desktop PC or laptop, the CPU Fan Issue is a popular error message. The warning is generally displayed when a computer has been forced to shut down owing to high heat.

When the fan (or fans) is unable to adequately cool the hardware, this occurs. There are numerous methods for determining the cause of overheating as well as the problem messages that appear and resolving them.

What Is CPU Fan Error?

Incorrect settings, physical damage to the fan, or external circumstances that cause the computer to overheat and force the fan to run at extremely high speeds are the usual causes of a CPU fan error on startup. Errors with the CPU fan can be brought by debris or other objects blocking the device’s air vents.

What Is A CPU Fan?

CPUs, or Central Processor Units, are your computer’s or laptop’s “brain cells.” The CPU is the central processing unit that performs the number-crunching that allows your PC to function. It does this with the help of electricity, with some of the electricity being transformed into temperature in the process.

The circuits inside the CPU will no longer carry electricity correctly if it becomes too hot, and the computations will fail. The CPU can get so hot in severe circumstances that the fragile electronic components are ruined.

The PC has a head spread, which is a steel disk that touches the CPU on one side and opens the other to the outside world, to fight this. The temperature spread is topped by a heat sink, which is commonly constructed of aluminum and copper. A tiny layer of thermal paste is sandwiched between them, filling any air gaps that may exist between the two steel faces.

The heat is transferred from the CPU to the heat sink via the heat spread. The heat sink must then be chilled. This is normally accomplished with the help of a connected fan that circulates air across the heat sink’s fins.

Why Does The CPU Fan Error Happen?

The CPU Fan problem can be caused by one of two scenarios. Either your CPU fan is malfunctioning or your PC believes it is. One of the issues that can go incorrect with your fan is that it does not spin fast enough to sufficiently cool your CPU. Another possibility is that the fan has entirely stopped.

If you see this problem after a forced closure, it’s most likely due to a hardware issue. It’s a negative sign if your CPU Fan was extremely loud before the closure. Your fan, on the other hand, could be absolutely silent since it’s stopped moving, which isn’t usual.

Because the CPU does not generate heat when it is idle, some new motherboards allow the fan to be turned off, although the fan should always be spinning. A fan speed issue occurs when the fan’s reported speed differs from what the computer expects or falls outside of the expected range.

Best Solutions To Get Rid Of CPU Fan Errors

Move Your Computer

If you store your PC in a location that receives a lot of direct sunlight or is frequently hot, it can overheat and shut down, irrespective of how much cooling the fan provides. Move your PC to a cool place or make sure it isn’t in the bright sun all day to fix the CPU fan problem. Check to see if the CPU Fan Failure hasn’t occurred yet.

Clean Vents And CPU Fan

If Method 1 fails to resolve the issue, you can inspect your PC and its vents for dust. If this is the case, clean them right away. The easiest approach to clean vents is to use a vacuum cleaner brush to remove any dust or debris.

To clean the CPU fan, you must first switch off your PC. The CPU fan should then be cleaned with an air gun or bottled air. Cleaning substances should not be sprayed on any parts because they can significantly damage several of them. Many devices aren’t meant to be opened in the first place. If this is done, the warranty will be voided, and serious damage will result. Seek professional assistance.

Check CPU Fan And Its Location

Physical issues with the CPU fan, as previously stated, may potentially cause the issue. As a result, inspecting the CPU and its location may be beneficial. If the CPU fan becomes loose or falls. As a result, depending on your fan model, you’ll need to reattach your fans using a screwdriver or adhesive.

When inspecting the electric device’s inside, make sure it is totally turned off (not in sleep mode) and disconnected from the power supply. If you’re going to install the CPU fan yourself, ensure sure the position is correct.

It should be linked to the motherboard’s CPU header. The three holes (three-pin connector for the fan) may be labeled “CPU Fan” on the CPU header, but if not, you may easily discover them. If you move the fan to another location, it may start running when you switch on your PC, but it will not be able to sufficiently cool the CPU.

Reconnect CPU Fan

On the PC motherboard, there are many CUP fan connection connectors, allowing you to connect multiple different kinds of fans at the same time. Furthermore, these various types of fans can be connected to other PC components. As a result, you’ve most likely plugged the fan into the wrong port. As a result, you’ll need to attach your CPU fan. Then see if the fan is working properly.

Change A New CPU Fan

If none of the previous alternatives work, your CPU fan is most likely to blame. To solve the problem right now, replace the CPU fan. You can send it to the store if your PC warranty covers fan repair or if the fan has its own warranty.

How Do I Get Rid Of The CPU Fan Error On My Asus?

• Enter the BIOS of your computer.
• Go to the CPU Fan settings page. Depending on your motherboards, the sections could be different.
• Find the parameter that controls RPM warnings right now.
• Lower the default value to 300 RPM and save adjustments.
• Boot the system after exiting the BIOS.

Why Does My Computer Say CPU Fan Error?

What Leads to CPU Fan Issues? Incorrect settings, physical damage to the fan, or external circumstances that cause the computer to overheat and force the fan to run at extremely high speeds are the usual causes of a CPU fan error on startup. Errors with the CPU fan can be brought by debris or other objects blocking the device’s air vents.

Conclusion

The worst-case situation is that your fan isn’t cooling your CPU well enough, causing it to run hot all the time. It will automatically turn off the PC if it gets too hot, but even running the CPU at that important heat for long periods of time will limit its life. That’s all about CPU Fan Error. Hopefully, you got it all!
