Why is the computer fan not spinning? How to fix it quickly?

Laptop cooling fans are essential for the operation of laptops. Helps dissipate heat for laptops to ensure stable temperatures when in use. Users may encounter some cases where the laptop cooling fan does not run , the computer fan does not rotate . Let's find out the causes and how to fix them through the following article.

Reasons why computer fan does not spin

There are two main reasons why a computer fan does not spin: it is broken or the temperature sensor is broken.

For desktop computers, the computer fan not spinning may be due to a broken fan, a broken wire, or you may have plugged the battery into the wrong pin. PC installation errors are very common and it is normal for the computer fan to not spin if you plug in the wrong wire. You should check the wiring to see if there is any problem!

For laptops, the fan system is pre-installed and sealed inside the machine, so the main reason can only be that the computer fan is not spinning due to damage or the temperature sensor is damaged.

Computer fan not spinning due to damage

It may be caused by the wire or fan blades not being able to rotate to dissipate heat when the laptop's temperature rises. From there, the temperature of the device will increase steadily and affect the speed and quality of the laptop's work processing. The computer fan does not rotate, causing the temperature of the machine to increase, the risk of overheating causing the machine to shut down and suddenly reset. This is extremely dangerous for your PC system as well as the data you work on and store on the machine, so immediately find a way to fix it when the computer fan does not rotate.

Computer fan not spinning due to broken thermal sensor

The thermal sensor acts as a switch to stimulate the cooling fan to run: when the computer is off or in low-activity mode, the computer fan does not spin or spins slowly; but when the computer is running hard and the temperature increases, the thermal sensor will send temperature data to the processor and request the fan to spin harder to dissipate heat for the entire system. If this sensor is broken, the cooling fan will not be able to run when the laptop's temperature rises, even though the fan is still able to run normally.
