    Hello,

    First - I have searched for solutions for hours now, but nothing works, or I am lacking the ability to code the script properly

    Issue - My fan sensor is broken and reads as 0 RPM, with i stat nano, SMC control and HD fan control. The fan runs at maximum speed no matter what the laptop is doing. I have tried the SMC / PRAM reset but it does not fix anything.
    Temperature is fine, usually a cool 40*

    Is there an easy solution script or program in laymen's terms that I can run to set a maximum fan speed to bypass the faulty sensor? or is my only solution a new logic board?

    There is nothing you can do.

    1) Replace the fan (if the fan is defective), or
    2) Replace the logic board (if the SMC is defective).

    Best course of action is to take the system into an Apple Authorized Service Provider and let them look at it.
