The reasons are: 1. Fan connection problem; 2. Fan failure; 3. Fan blockage or dust accumulation; 4. BIOS setting problem; 5. Motherboard failure; 6. Other reasons, etc.
CPU Fan Error refers to an error in which the computer system detects that the CPU fan is not working properly or has malfunctioned. When the computer starts, the system will detect the operation of the CPU fan. If the fan does not work properly or runs too slowly, the system will issue a warning and display a CPU Fan Error. This error may cause the CPU to overheat, affecting your computer's performance and stability.
There can be many reasons for CPU Fan Error, some common reasons are introduced below:
1. Fan connection problem: The fan may not be properly connected to the CPU fan slot on the motherboard. This can be caused by things like a weak connection, a loose plug, or a damaged cable. If the connection is poor and the fan does not work properly, the system will detect a fan failure and display a CPU Fan Error.
2. Fan failure: The fan itself may fail, causing it to fail to operate properly. This could be due to things like a damaged fan motor, worn bearings, or damaged fan blades. When the fan fails to operate properly, the system detects fan failure and displays a CPU Fan Error.
3. Fan clogged or dust accumulation: Fan blades and radiator may not work properly due to accumulation of dust and dirt. When using a computer for a long time, the fan and radiator will inhale a large amount of dust, causing the fan speed to drop or stop running completely. When the fan fails to operate properly, the system detects fan failure and displays a CPU Fan Error.
4. BIOS setting issues: Some motherboards provide the function of monitoring and controlling fan speed. If the fan speed is set too low or the fan monitoring function is turned off in the BIOS settings, the system may mistakenly believe that the fan is faulty and display a CPU Fan Error.
5. Motherboard failure: CPU Fan Error may also be caused by motherboard failure. The fan slot on the motherboard may be damaged or not functioning properly, preventing the fan from connecting or functioning properly.
6. Other reasons: There are some other reasons that may cause CPU Fan Error, such as power supply problems, temperature sensor failure, incorrect cable connection, etc.
To sum up, the causes of CPU Fan Error can include fan connection problems, fan failure, fan blockage or dust accumulation, BIOS setting problems, motherboard failure and other reasons. When solving the CPU Fan Error problem, you need to carefully check and eliminate these possible causes, and take appropriate measures to repair or replace the fan to ensure the normal operation of the CPU and the stability of the system. If you are unable to resolve the issue, it is recommended to seek help from a professional or computer repair technician.
