That and perhaps they did think about the possible physical stress from an impact as I mentioned (maybe, I don't know). Regardless, the thermal pad is better than most electronics where the heatsink just sits atop the PCA with air in between to act as a thermal transfer medium (and radiation is not nearly as effective as conduction through a thermal material). I personally wouldn't worry about the design. Those thermal pads work fine in most environments except in vacuum.

i mean i do know about wat thermal pad or thermal past is. I used to mod heastinks to fit onto CPUs in the past. But isn't 2 mm a bit too much for the heatsink to be away from the heatspreaders?. Btw do open up and ensure that the thermal pad covers all your heatspreaders. There were 2 rows of heatspreaders on my esc that was not in contact with the thermal pad.
