I finally solved my FANS BLOWING AT HIGHT SPEED problem (hardware solution, no software)
Running the Apple Hardware Test (booting with D key. If you are in an infinite loop, you need to be connected to your modem physically) send me the “4SNS/1/C0000008 : TAOP - - 124 “ error code, relative to the Ambiant thermal sensor.
It seems that it’s really easy to invert the ambiant thermal sensor as you replugged it into the socket (step 28 as you remount your mac).
As visible in the picture in step 28, the grey cable should be oriented to the bottom of your mac as the black one must be to the upper side.
Don’t use software solution because your mac is really downgrading performance (espicially GPU usage) in order to prevent burning component.
