Kenwood KAC-X301T and KAC-X201T:Do they share the same board?

[spooney]

I see in my KAC-X201T that there is spots to mount additional fans.I have a KAC-X301T on the way that i believe already has fans in those locations.If possible I'd like to add fans to the 201. I'm curious as to whether these two amps share the same or a similiar board and if so would it be possible to add fans by tapping into a certain spot on the board or if maybe even the 201 already has a spot for this on a connector on the board.

The simplest way to do this is to use the fan drive output to trigger a relay (connect the relay to the drive circuit in place of the original fan) then use the relay to drive all of the fans.
