calling all geeks

my laptop is too hot. summer is coming and there's no way i'm gonna sit thought the summer with this on my lap. what are my options?

do i buy a new (cool?) laptop?
do i get one of those things a laptop sits in to cool it? arent' they horrible noisy?
is there software? i've tried Speedswitch and Speedfan without luck - but then I couldn't really understand the instructions.

enquiring mems want to know
