My SWiM-16 is in a room that has A/C and the room pretty much stays at 75 degrees (+/- 1 degree). The SWiM-16 has plenty of air around it for cooling, yet it is very hot to the touch. The surface temp of the SWiM-16 measures around 120 degrees. Is this normal? I might think outside in the sun this might be more the norm (though still not good), but this just seems rather extreme for an electronic device to me as I cannot remember another multiswitch ever being this hot.
