A couple of days ago my late 08 mbp's Ethernet port stopped functioning and I had to send the computer in to apple to get a logic board replacement. I now have the computer back in my hands and it's working fine, but my concern is why the issue occurred in the first place and will it happen again? I spend a lot of time playing a game on my mbp that causes it to run close to 80degrees Celsius for many hours at a time. My computer never shut down b/c of heat or showed any other signs of issues but is it possible that having it run that hot for so long could have caused damage? I'm asking b/c I'm wondering if I should bother buying one of those laptop cooling pad things. Or maybe the damage was caused by something out of my control? Any input would be appreciated.
