I'm having overheating issues with my sundance. It seems to go to the 3/4 mark or a little more(what ever temp computer set to turn fan on) when at idle around town driving and while going up hills at highway speeds. When the fan kicks on, or I turn the fan on with a switch I installed it cools all of the way down to below half. If I leave the fan on it will never go above half. I'm using a t2 rad w/ a fmic directly in front. Do you think i'm restricting the airflow of my rad with my ic in the way or is my rad clogged or something (Didn't look bad, no fins missing/bent)? Or should I look elsewhere? Also using 180* thermostat w/hole drilled.
