Wouldn't you also get more hardware errors, causing e.g. sudden kernel panics and stuff like that? And wouldn't that damage the brand more than the speed improvement is worth?
Yeah. One could argue that if you are getting hardware errors you are already at the red line (and not just close to it).
Regarding damage: It depends what your goal is. Some people want to get as much performance out of the CPU as possible since they maybe upgrade after a year or two anyway. Some people even try to set records by using crazy cooling systems.
