Well, I got a new HP dv9700t for college, but when I play games on it or run any intensive task, it heats up to really high temperatures. I don't want it to break, so I'm trying to cool it. I bought a $40 Rosewill laptop cooling pad, but my GPU still stays around 90C under stress. The Rosewill pad has a nice metal slab to take the heat off, but only two puny USB powered fans that don't put out a whole lot of air.
However, I had a dead dual-fan desktop power supply laying around as well as a fan I tore out of a different power supply (replaced it with a blue fan).
I also had another old PSU lying around that I replaced when I upgraded my graphics card. So, with all of these, I built a very effective laptop cooling fan.

First, you need to make sure you need a cooling device. If your laptop is only ever used for web browsing and document editing, chances are, cooling units won't help. If you play games a lot, then you'll probably want a cooling device, as gaming stresses the CPU and GPU and causes immense heat output which often can't be handled by the single small fan most laptops have.
Use PC Wizard (www.cpuid.com) to inspect the temperature of your CPU, motherboard, and GPU as you play games (I hooked up a second monitor, put PC Wizard on it, then fired up games and watched the temperatures change). You can minimize PC Wizard and it will have a small status/temperature notification at the top right of your screen.

Freezing point of water = 0C
Boiling point of water = 212F
Freezing point of water = 32F
This is at standard pressure (1 atm). I suppose that on the top of some really tall mountain or on an airplane without a pressurized cabin, you could probably boil water at 80C, but then again you can boil water at room temperature if you lower the pressure enough.
80C is high, but then again it's a powerful GPU in a laptop. It was over 90, but with cooling that problem is solved. I too question how safe that heat is, but apparently it must be fine or else they would have designed it with more fans.
