I'm not sure why but I've seen it mentioned several that if you're under geared the speedo gets hot and over geared the motor gets hot.
Maybe the speedo was hot on the inside but with the alloy case and fan most of this heat was dissipated so it still felt only warm to touch.
When ever in run a speedo/motor combo from different manufacturers I always disable the motor overheat protection though as this protection only really works when both are the same make.
