Custom (very) Quark esc heatsink...

[zeropointbug]

Which part are you not convinced about?

How about this, once I get my thermal adhesive, my thermal probe (infrared), and my truck up and running, we will see how well it works. I know with absolute certainty that this will work super fan-taz-magorical.

Don't forget about air convection through the fins too (without fan, or direct airflow), as I also tried using no fan with the heatgun. I couldn't get it over a temp that I couldn't put right to my cheek right after, from about 1 minute of blowing the heatgun directly on the heatspreader, about 2cm away.
