the Macbook Pro, the hottest laptop out there (and not just in terms of the way it looks). But it seems like you'd be stressing your laptop a lot, so I'll suggest some stuff I *need* to use with the Macbook Pro (even at idle... do anything demanding and it's hello barbecued thighs).
I have the Rain Designs iLap for the 17", which is an aluminium plate which dissipates heat and also keeps the laptop clear of the desk / lap.
I also have the Griffin Elevator, which may or may not be compatible with other laptops (the MBP has a flat bottom and the stand needs that to work). This is a raised stand that you'd use on a desk with a separate keyboard and mouse.
You could also try Cooler Master's stuff, which features active cooling (i.e. fans). I believe the Notepal W1 will be a nice snug fit, just 2cm wider than your laptop and almost an exact fit in terms of depth.
I recently purchased an HP Pavilion dv9428nr 17 inch laptop. I love it. its light years better than the 700mhz celeron i've had for years.
anyways i'm concerned about cooling since I use the pc quite often and am also condensing a lot of old cdr's to dvd.
what is the best method of cooling the pc down and are there any cooling pads out there specifically built for 17 laptops or can i get by with what's out there?
