Dorades, scoops, and fans are all active methods of creating ventilation for the engine space. The extra effort to move air over the alternator is a positive action.

An alternate method is to modify the alternator output. Alternators can use temperature sensors to reduce their output to the batteries. Balmar added a twist to this with its Belt Manager function on the 614 regulator. You need to program the feature. Your action can reduce the heat generated by using less belt-produced energy.
