I have two Quark 125's that use the top plate (connecting the three diffs) as a heatsink and it works wonderfully without the need for any additional active cooling. The chassis is another good heatsink and gets lots of airflow. I just wish more ESCs were built similar to the Quarks in how the FETs are mounted...

You're absolutely correct.. I've tried cooling with the TEC from ebay... it was just a waste... although it's good for cooling the motor after running, but during running... it's just a waste... Although it could be good for a closed system water cooling for the bigger scale stuff.. if you could have the hot side exposed on the outside..
