As the title says, Whats the best non overheating, ext wifi quad core? Compact size in stick form factor would be good but is not essential, and do all these quad cores need external power? no usb powering?

We recommend the Tronsmart MK908II for a stick.

for the BOX, you don't need to worry about the heat. they have enough room for heat
