Nothing strange about it.

Everything above 5V x current flow equals the redundant wattage converted to heat (it's more complicated than this BTW but just for illustration) and of course the device itself produces heat too for example in it's CPU. Someone on CA measured power usage and the Mutec plugged in uses approximately 2W but he also talked about a current draw of 0,35A @ 5V which would mean 1.75W. The Mutec uses the USB bus power besides it internal SMPS for extra power domain isolation.
I've used a Intel CPU cooler (fins only, not the fan) for extra cooling before I got the PH PSU which now feeds 7V to the mR. Actually the cooler is still on it, it's out of sight here, and it won't hurt. Of course whatever heat sink you put on it, ventilation is still needed to let the air convection cooling principle to do its work.
