MM is way too hot! Why?

[Xtremespeed]

Just a quick update. Changed my pinion to a 13t this morning and went outside. My Neu was at 112 after about 10min pretty hard running and the MM about 190. I can't hardly tell the difference in top speed between the 2. Cogging is non-existant except for if I try to go full throttle from a dead stop. I had ordered a couple fans already, and they should be here tomorrow. This may be ok once I drill the case and get the fans on there. At least I think it will get me by until a better esc comes along. Thanks everyone for the help.
