Vim3 thermal with the new heat sink

30-minute Antutu 8 stress test on the Edge-V (RK3399), using @RRZC777’s large passive heatsink. I stopped the test at 30 minutes, as the SoC was experiencing significant thermal throttling, and since our aim is to avoid that, I saw no need to proceed further.

Ambient temperature was at 30C, and the likely equilibrium temperature would be 75-80C. This is already too hot for most people’s standards.
