F/R brake temperature?

For rotor temp measurement after a cool down lap, assume OEM Akebonos and no brake cooling ducts: the front rotors are just tiny bit bigger than the rear in diameter (355 vs 350mm), but thickness differs greatly (32mm vs 20mm). The front rotors carry a much greater volume of heat with not much more surface area to for heat dissipation. With a method like using an infrared temp gun, which measures surface temp, I would not be surprised there is a temp difference, even if the peak temp during braking may be the same between front and rear rotors.
