Ditto to that. I have an  HP dv3 laptop that often heats to 90-100C
degrees for no obvious reasons. When doing something more intensive,
it may get to 105C and if it stays there for much longer the computer
powers down. It's clearly a badly designed laptop as far as the
cooling goes (sometimes I wonder if I should use it to prepare
scrambled eggs with bacon for breakfast), and one of the few things
that helps me cool it down is the "ondemand" frequency governor.
