I've been using a Targus lap chill mat
with my sony vaio 17inch laptop for a year now,
before this the laptop had a tendency to get hot on the left hand side (mostly the QWERTY section of the keyboard)
but since using the Targus mat this has been reduced greatly
My best mate bought an Asus laptop 2 years ago which got so hot you could have fried an egg on it!
He purchased the Cooler master Notepal U2
(has two fans you can fix anywhere on the pad for best fan placement)
and has noticed a drastic reduction in heat.
both of these i found very good to use(both USB powered)
also consider getting your laptop serviced as it could just be clogged with dust
good luck anyway mate
