RB493GAH

I have bought an used RB493GAH a few weeks ago. I am using it with one CM9 card and I am concerned about the temperature of the device. It does not go under 40C with a cooler at room temperature and goes over 60C without the cooler. Should I be worried about the temperature or just plan for constant cooling when I make a case for the device?

The device is powered by 24V 0.8A, but I plan to use a 12V power supply as a permanent solution.

I appreciate all the help I can get.
