Just curious but when you have the lamp supply and the electronics separated, does whichever fan cools the xenon bulb get powered from the lamp power feed or from the electronics feed.

I am almost certain they are powered from the electronics supply...
From memory the fan controller daughter-board is connected to the PJ/DIV board, which is of course part of the electronics supply circuit...

The only fans that the LPSU controls are its own.
