That's good! Yeah, the case gets hotter now, but that tells me the heat is getting to the case faster and not staying in the ESC. So, if you were able to run without the fan, a simple addition of more heatsink area to the case should let you run with no fan at all (in case you haven't heard, I hate to use fans in an R/C).
As do I, that's why I'm gonna make my custom Quark case, should work lovely. :017:
