OK, I just ran the Quark with a total of four caps. I ran it for 5 minutes as though I was trying to break it. 50' sprints back and forth with the 9XL geared 13/46 with a maxamps 4S 8Ah pack.

The sink temped at 135, the center heat spreader was at 145, and the caps were at 150. The lead connectors were also at 150. I'm wondering if the power leads are heating up the capacitors or vise versa. I think that more caps are definitely in order. I'm going to have to figure out how I'm going to mount this thing. I am now believing that the stock case is less than ideal.

I just can't figure out how so many are running the Quark without heat issues or adding caps.
