Note:

For 4-6 cells NiMH or 2 cells Lipo: You don't have to change the cooling fan that comes with the ESC.

For 7-9 cells NiMH or 3 cells Lipo: You must change the standard cooling fan. It cannot work with such a high voltage. Please choose a high voltage fan or supply the fan from the receiver (+6V).
