Strange that you're experiencing those kind of temps! My buggy runs the same (but older) motor on 4s 4900mah through a V1 MMM and 18/44 gearing (diffs are 11/38). Top speed is about 45mph, and the motor typically doesn't break 160 deg. F, the battery stays under 100 deg. F, and the fan-less MMM heats up to about 120 deg.

Your setup probably isn't pushing more than about 36mph, which makes me wonder if there is any binding in your drivetrain, or like Josh suggested, a short in the motor.
