It strikes me that many laptops are designed very badly.  They feet are
too small (you can buy bigger adhesive rubber feet from electronic
stores, so you can do a neat upgrade), and they put the vents on the
bottom instead of the side (making it nearly impossible to actually use
some on your lap).

Possibly the delay taken before heat propagates/dissipates.  I'd suspect
that if you were getting such an extreme response, and with a long
delay, that perhaps there's a problem with the cooling system (blocked
fans or ducts, badly fitting heatsinks, loss of heatsink paste between
the heatsink and the hot device, etc.).
