We always recommend running the fan on the ESC regardless of the application: A cooler ESC is a better running ESC...but in most cases with a 13.5 the system will not generate too much heat and you'd more than likely be safe running without it.
If you would like another fan sent to you you can PM me your address and I can try to have one sent to you.
Received the replacement fans, thanks Steve!
Could you give me some information regarding the 13mm rotor, like what it does different, gear ratios etc?
