Yep, I write this from a MSI Alpha 17 w/ 7945HX... I have the CPU undervolted and also I have the wattage capped at 65 (130W out of the box) so my all-core performance is much worse than originally so that I can keep the temps from continuously hitting 90C and the fans from running hard all the time.
I have a cooling pad with a sealing frame on top of that to force air through the laptop to keep the components cool.
As far as gaming; it actually gets better performance like this in most games I have tried.... since it isn't overheating.
