[Insert Custom Title Here]
I know I've mentioned this in several other threads, but here it goes again: Heat is not an issue.
You may notice that the Pandora itself does not have active or passive cooling. It doesn't even have ventilation holes in the case. The SoC does not get hot.
It's been a long time since I've been in a physics classroom, but lets do some really bad science.
Joules = watts x time in sec.
Temp rise = joules / mass in grams / specific heat of mass
If we assume the Pandora has a mass of 300g (slightly more than the original DS), and the SoC is responsible for .25W of heat load (the maximum TDP), and the average specific heat of the device is 1 (this is WAY too hard to calculate accurately. It's probably between 1 and 3), then an OMAP 3530 SoC running balls out for 1 hour could theoretically account for a maximum system temperature rise of about 3C. And that assumes that absolutely no heat escapes from the system through conduction. It assumes about a thousand other things too, but you get the idea.
I know this isn't anywhere near accurate, but it paints a pretty good picture of the sort of temperatures we're dealing with. The heat generated by the SoC is minimal. The heat generated by the other components is minimal. You could entomb your Pandora in three feet of neoprene and it still won't overheat.
