yeah, its natural to want to believe that such extreme volts/overclock would result in such a dramatic explosion if its liquid nitrogen super cooling somehow was suddenly reversed, but its a simple alluminum heatsink - albeit not even attached to the CPU and the fan has "failed"...now unless experement took place in the middle of Antarctica in the middle of July...
Ofcourse to run @ 3.8GHz with a 12.5 multiplier, you'd need a FSB of over 300MHz, something I don't know of any old K7 motherboard capable of doing, and certainly not with the stock passive aluminum heatsink and stock volts on the chipset.
Someone should make a spoof using a Pentium D to start a campfire or something, perhaps use it to fry some eggs...
