Alienware M17xR3 GPU Fan

On first power on, the gpu fan spins then stops. The issue is, it never comes back on so the laptop overheats and shuts off. CPU fan will come on when its heatsink gets hot.

Fan is replaced but still same. Is there a sensor nearby?

measure voltages on all pins of the fan connector before and after when the fan stops.
