I plan on queuing up a few (~5) DVDs in HandBrake to encode for the night. My 2.4 GHz Penryn has never gone above 80C while encoding a single file that takes 35-40 minutes. I live in a dorm room and we crank down the thermostat to around 60-65F before we hit the hay. Although I shouldn't have to question the reliability of my $2000+ laptop, the heat (and some of the threads I read here) really irk me. Should I be fine letting it run over night?
