It's fine for the fan to run, thats why its there. The max safe temp IIRC is 180, at least thats what I think the thermal shutoff kicks in at. I wouldn't be to concerned about the temp of the esc, it has the fan there as well as a thermal cut off to protect itself. Worry more about the temp of your motor and lipos. Also your saying not even hot to touch, get a temp gun, it's $25 well spent to protect all your electronics, trying to guess the temperature by feeling it is just being a cheap skate, spend the money and get a temp gun!!!
