Your chosen thread title, "Laptop a Liar?", is mostly not true, but the name itself we use when talking about these portable computers is at least misleading, if not a lie; the worst place to keep a laptop is on your lap.
To keep it cool, use compressed air to clean the air vents, place it on a cooling pad or at least on a level surface to let air circulate underneath. I keep a wine bottle cork cut in two half's in my laptop case, to put under the rear corners when using on the road.
Avoid simultaneous use of programs that need a lot CPU / GPU power, put laptop to sleep or hibernate it when not needed instead of leaving it running.
Doing all this, my dual core temps stay between 40° and 60° Celsius (104° and 140° Fahrenheit), even though the laptop is almost always on and I use it constantly.
