At ~700mA for all channels (with dimming it would be less) and assuming 30% efficient emitters we are at about a conservative 65W that this needs to sink away. Most of the emitters are better than that (low 40%). The thermal resistance from package to heat sink is an unknown at this point, so I don't have a good estimate on die temperatures.

Forced air is required, but probably not much.
