the sc10 4x4 can be geared correctly all day long and still have temp issues. the motor is in an area that does not get enough airflow. its that simple.

thats why many have done the fan mod.

admittedly like ive said before iam a heat freak, i dont want to burn up a motor so i look for the best ways possible to keep what i have cool.

im gonna drop a tooth from what i was running with the fan and try again tomorrow. cross fingers , lol.
