silly question on brushless motor

[lodders127]

i had a ezrun 35a esc with a ezrun sensorless 9t motor and my esc fan caught fire because i was running it off of 11.1v lipo so i got a team orion vortex 100a esc and it is fast but i dont know if there is a amp limit for motor
can i run this motor with a 100a esc?
and also as i dont race im just wondering what setups do people run like wat volt battery and wat turn motor (im guessing 10.5t) and all that
im running a 9t motor on 11.1v lipo
is that a bit silly should i go down to 7.4 v?
