Ran 82.5/41.25 on my bx board for years. I have a Maxtor 4.3GB hd that's in my current system and was run at the 41.25 speed for perhaps 3 years & it's still fine as is an IBM hd that was run for 2 years. My current ATI radeon VIVO AGP video card was run for at least a year at 82.5 (and overclocked itself) & its still running fine in my current system. I wasn't an avid overcloker and used no cooling other than what was on the PSU - never even monitored temps or anything. So it appears the long-term effects, whether from the extra juice or the heat, are minimal...
