CPU fans are what keep your entire system from overheating. When this specific component stops spinning or spins at a lower RPM, hardware such as the processor chip andgraphics card will overheat. And to prevent itself from any damage due to extreme temperatures, it stops functioning.
Whether it be low power from the PSU or dust settled on fans, your PC will inevitably turn off when the fans stop spinning.
In this article, we are here to provide you with specific guidelines to fix a CPU fan that is not spinning.
Why is My CPU Fan Not Spinning?
Depending on the type of fan, there are several reasons you might be facing this issue. If it is the CPU cooler fan, the first thing you would want to check is whether the CPU cooler fan is connected to CPU_FAN or the SYS_FAN on your motherboard.
However, if the system fans have stopped spinning, you might want to check the dust settled on the fans. As the system fans sit just on the edge of the PC case, they are affected due to dust the most.
Besides this, here are some other reasons your CPU fan might stop spinning.
7 Solutions to Fix a CPU Fan That’s Not Spinning
Here are some solutions you may attempt to fix both the CPU cooler and the System Fan.
Check CPU Fan Connection
The first thing to do when you see that the fans in your computer do not spin is to check the motherboard’s connection.
If your CPU cooler fan stops spinning, ensure that the wire from the fan is connected toCPU_FANon your motherboard. And if you see that the case fans stop spinning, ensure that cables from these fans are connected toSYS_FAN.
Try removing these wires and reconnecting them again if the CPU fan still does not spin.
If it still does not work, try using a different header on your motherboard. Most motherboards will have two or three CPU_FAN headers. you may use these headers if they are not in use. As for CPU case fans, you will have multiple SYS_FAN headers. utilize the one that is not occupied.
If the CPU case and the CPU fan still do not respond after reconnecting them, you may access the BIOS to verify if the motherboard detects the fan. Your BIOS has all thedetails about the hardware componentsconnected to your motherboard.
