Warning, do not touch your Mosfets without protective handwear. The note about eggs and frying applies to the mosfets also. Note how they are not remotely evenly loaded. I'm sure there will be some valid reason or other  for this. I am not an electronics expert.

The chip to the right of the mosfets gives out a fair amount of heat and has been shown to be a candidate for heatsinking, but the other two small chips I've seen people recommend as prime heatsink fodder are barely warm on my 8rda+. Maybe these get hot rapidly as you raise the VDD
