Hello, 

 

I own  a HP Pavillon Gaming Laptop 15-cx0xxx. 

1 month ago, my PC started to display an error message while starting : "The system has detected that a cooling fan is not operating correctly... (system Fan 90B)".

I have replaced the concerned fan (CPU) with a new one. However, it did not solve the issue. Knowing that it might not come from the fan I tried to plug the new (and old) fan on the GPU fan plug. When plugged on the GPU fan the new and old fan were spinning. 

I updated the BIOS and set the BIOS to default setting but it didn't solve anything. 

 

Have you got any solution ? Is it related to the motherboard ?
