Hello, I would like to know what is the optimal temperature for an active multiface II. My I/O Box is freely positioned, raised both above and below and powered via the original power supply. Unfortunately, even after a short usage the BOX temperatures is very hot, so hot to burn almost to the contact. It's normal all this? It could be a power supply problem? There is difference in temperature fueling the card directly through the PCI interface?

Thank you.
