hobbywing ez run 60a combo

[wookiee76]

Hi guys and gals, just getting back into the hobby after a decade plus break and have got a losi 22 2.0 for starters with the aforementioned hobbywing combo. My question is is it ok to run the speedo without the fan as with it it doesn't fit under the shell in a mid motor configuration or do I need to rebuild it to rear motor to get a bit more chassis space?
