I got the firmware from this link:

The fan worked perfectly before the firmware update.  I have done no hardware modifications to the board, only upgrading the firmware.  So I am not convinced that I messed it up.  Are there any other ways to test this idea?

Long story short:

I hooked up my extruder fan to the pins I soldered in place... it worked before the firmware update and now it does nothing.  There is no voltage coming from the motherboard fan board pins when checked with multimeter... the fan works fine under other power.

Everything else works fine.

(only posted after scouring forum, I figure I am missing something obvious)

Any ideas?
