Re: Laptop cooling.
Walmart & Best Buy laptops are notorious for these heat issues. I believe it has something to do with the lowest bidding dollar. HP did not think when they designed their heat sinks, probably had a couple hundred thousand laptops on hand and sold them cheap to walley world, I've opened up about a dozen of these and whenever I do, I put a 1" x 1" copper shim in and they haven't come back with heat issues. I've had to re-seat about 6 video chips due to over heating. (The DV 6000-9000 is what I'm talking about)
The main problem is getting them all back together and all the 1000 parts and screws. replacing all the ribbon cables because their made by the lowest bidding dollar as well and if they get a crossed wire, you get a toasted board.
I also have in my store a Qosmio x305, a consignment, and this thing doesn't even get warm compared to what my tx1000 does. I've got that one kicking out about 130 degrees with a thermal gun.
Basically, it's what you have for heat sinks and fans. I think that's why towers last much longer than laptops for gaming. Towers you have your processor with it's own big butt heat sink, your video cards in gaming pcs and even most personal computers have their own heat sink with a fan.
The Qosmio I have, a high end laptop, it's about an 8" by 1" by 2" condenser/heat sink on the back of it to keep it cool. No problems there.
