    Only one side of laptop fan working


    I'm just trying to come up with ideas that might explain the symptoms, based on limited information.
    I still don't know what the second fan is for.

    The only thing that makes sense to me right now that would explain what you are describing is that the wires are somehow "crossed". If the left fan only works when the right is unplugged, what else could explain that?

    Apparently the CPU and GPU each have their own fan...

    Looks like the gpu is the right side and cpu fan is left side. So gpu fan is on full blast while cpu fan is idle. Things to know, I disable window update with policy editor while ago, don't know if it matters.

    Actually both fan are able to work at the same time, but seems like the gpu fan is on full blast all the time
