Only one final thought is that the heatsink was "radiating" more than the motor and fooling your temp gauage.

Or it could be the color and/or composition of the heatsink has a different emissivity rating than the motor. IR thermal probes are somewhat sensitive to that setting, which is why you are supposed to set the emissivity to whatever material/color you plan to use the most.
