Also, try running with the cover off of the case. This will tell you if the trunk is too hot, or just the air inside the case.

No, I actually swapped the mo-co-so case out for a
silverstone sg05-b because I couldn't find a heatsink that would fit the mo-co-so case. This silverstone has a nice big 120mm intake fan on the front of it, and lots of areas for ventilation on the sides. Plus I removed the AC/DC PSU box, so there's a big whole in the back where it used to be. The problem is most likely the hot air circulating in the trunk after sitting in the sun. There's lots of good airflow in the unit, but since the source of the air is hot, the circulation doesn't help much. I need to somehow get some cool air into the trunk (maybe tap into the AC, pull in some air from under the car, dunno, anything...)
The Opus PSU sits vertically to the one side where a PCI slot would be for an atx motherboard, and the power cables go out the rear of a PCI slot opening.
I need to modify my airflow diagram, because turns out the two CPU fans don't push air across (from right to left) like I had thought, they both push air out from the center (both blowing from the CPU out). So the only intake air is from the 120mm fan from the front of the case then out both sides of the CPU.
