The Quark was running a lot cooler but I don't know if it was from the grearing changes or both. It was at least 90*F that day and the Quark was at 112* after 20 min and usually it is at 130-148*F. You can't really see it in the pics but I have the heat sink and 2 of the 40mm fans underneath the ESC. I wish I had more of a definite answer.

Btw those caps are the 270uf ones.
