Well just to ruffle the fur a bit more... the zeddy isn't entirely 'closed'... so sone heat does escape...

and due to its black case, it is nearly a perfect black radiator, able to emit a lot of energy as thermal radiation :mrgreen:

Maybe, but the thermal conductivity of the ABS plastic is not exactly great...

A warm Zeddy does work nicely as a hand warmer. Just need two in winter, one for each hand :mrgreen:

Incidentally, if you have a fan in your machine and that results in a forced airflow over the ULA (and 7805 if you are still using a series voltage regulator), then the ULA does not need a heatsink...
