) and my little sister (First in Electronic Enginerering from a decent Uni, designs PCBs and electronic devices for a living) are pretty much violently disagreeing with you in terms of the real world ie. you are 100% on the theory, but you won't see a measureable change inside 12 months - certainly not enough to change a stable overclock. This is not my opinion, it's just I'm stuck with them for a family Sunday and I made the mistake of asking their advice.
