Hi guys, this is my first post, I have do this mod to my HI10 and I have obteined around 10-12ºC less, working at full charge max 73-75ºC.
I have to say that it can do better, but I’m not very pacience and I’ve done it with the materials that I’ve found at home :).
Better than a coin… You can use a 20x20mm copper plate, and I use too isolate tape to isolate the pcb to the thermal compound (is an electrical conductor) and the upper metal plate.
