were did u here that? i thought i read all the AS5 instructions on there website, i dont recall reading that... is it on there? or do u have a link for it somewere else?
200hrs is only a bout a week, if thats true, at least its not that long.
EDIT: ok i just went back and i c what u mean... quote " it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity."
that doesnt mean u have to wait, it just means AS5 will not perform to its full potention untill 200hrs of running the comp along with a few shutdowns and restarts... to allow the cpu to cool and heat up again.(break in period)
