i'm lookin to MAYBE mess around with my computer. it's an HP laptop, AMD turion 64x2 1.9.

ok so, w/o getting crazy into overclockin what kind of boost can i expect? 2.4 2.5 ?? can you even add a fan to a laptop? when people say it reduces the life of the computer can you estimate that? like 50% / 20%?

any comments would be helpful
