Isn't that a bad idea... laptops have significant thermal limitations, things start going wrong quickly when you push beyond those. I've not done any serious overclocking but most seem to stick to desktop and buy more capable cooling systems to make it sustainable.

Aside from heatsink limitations (which can be modded to achieve better cooling), people are pushing their gaming laptops to 80W and beyond, with overclocked GPUs as well.

Some are resorting to dual PSU's to handle the power requirements, so the system boards are capable of handling some insane load.

I myself squeezed another year out of a Core 2 Quad laptop by overclocking everything as much as possible. Temperatures were averaging 90-95 under load, but I didn't care at that point, as I was going to upgrade. It still works :D
