i have a havoc sc pro in mine, i had to take the fan off for the body to fit. it runs 140-150 after about 8 mins on a 13.5 (75/30 gearing, 30 deg boost). motor comes off at 150ish.

no circulation in there.... i have the 10.5 in there now with 81/24 gearing, gonna leave 30 deg boost. i havent run it yet in this config so i dont know how the temps are gonna be.
