ALL modern processors draw extremely high currents at low voltage.
Haven't looked up requirements but probably 20A plus plus at 1.5 to 3 volts.

Even 20 watts (below any of above) on an unheatsunk chip will fry it vvv
quickly.

It may be that Intel's cpu's have a little more thermal mass than AMDs which
may allow them to survive for a few more seconds totally unheatsunk. (But an
eg  Celeron 1700 looks pretty minimal in any sort of mass to me).

Just possibly Intel's heatsinks are superior and without a fan they run
cooler.
But even then the temperatures they claim are bunk.
84 F = 27C
The heatsink on the Celeron 1700 I installed a few days ago runs annoyingly
hot with VERY large Intel heatsink and fan. I'd say around 50C !

Anyone here have any REAL figures?
