mgm compro 16024 awsome controller

[luvsrc]

i mounted mine sideways where the two heatsinks are both exposed sideways
wish i got it pictured with double sided tape and a ziptie mounted on my race bomb chassis,any body for a suggestion where to get the voltage for the cooling fan ? do i need to run it with a separate 9 volt battery or can i run it with my 4s lipo pack where the wirings are connected to the esc wiring, thanks for any input, will it loss a lot of power or hardly noticable at all?
