I wonder how effective a diamond heatsink would be? Diamond has a thermal conductivity about three to four times that of copper (and specially-made high-purity synthetic diamonds can get to about thirty times that of copper or even 100x copper if you can make them out of 99.9% pure ¹²C), so you'd expect better performance, but I don't know how well the diamond would transfer that thermal energy to air
diamond also has a much lower heat capacity than copper, too
@Motodrachen do they make those, or are you just elaborating on my diamond heatsink ponderings?
@Motodrachen I googled it and only got results talking about minecraft but I mean you _could_ make one
