|SpeedFan for temps|
Remember if you could run CPU at full speed all of the time, excessive heat will of course be a problem, but extremely short battery life is also a major problem. If your CPU speeds up whenever you need it, what is the difference if it slows down in between to run cooler and conserve battery power. Most computing does not use full CPU power except in short bursts. Some applications like gaming, number crunching, and some others may run your CPU more continuously, but not most, and the rest of the time it is idle anyway.
You have to be a little bit crazy to keep you from going insane.
