My regular MMPros do the fan startup.

In the 1 cell version, I do believe the lack of BEC will prevent the fan from running. And come to think of it, I thought the 1s version didn't even have a fan?

I wonder if a temp-controlled fan could be added with a little trickery? I know the BEC probably powers the fan, but is fan ground-switched , or positive rail switched. If it is ground-switched, you could run the fan - to the proper terminal in the port, and run the fan + directly to your external BEC.
