FORCED AIR THERMAL MANAGEMENT

To manage the additional heat associated with higher output capability, a thermally controlled fan has been designed into the PC4800.

When the heatsink temperature reaches a predetermined value, the fan is activated. Cool air is drawn in through the lower intake vents on the endplate. This cool air flows below the circuit board, through the fan and across the internal fins, cooling the heatsink.

The heated air is then forced out through the upper endplate exhaust vents.
