That is the same ESC im running in a Traxxas Bandit with Trinity Brushless 13.5T and 2S Lipo. It has never gone over 95F. Excellent ESC, espeically for the price
Little update. As most of you know, I'm having a micro ESC being made. The prototype is done. I will test it soon as I'm waiting for other products to be made. The production unit will have a thinner heat sink and it will have a capacitor bank with 2 caps (I attached a picture of the cap bank that will go on the 100A and 200A units). Here are some pictures of the soon to be 40A micro ESC:
