I'm running a first-gen MBP - 2.0ghz Core Duo, 15 Inch, 2GB Ram, 100GB 5400rpm HD. Purchased in March/April 2006. It's still a fine machine, and perfect for my needs. I won't be looking to replace it until the 32nm mobile quad-core generation hits. However, one thing that bugs me about it is how hot it gets. For example, if I watch a couple of youtube videos, say a few minutes each, it gets up to 70 degrees C, sometimes up to 78 degrees. I'm running smcFancontrol, and this is with both fans going at about 6000rpm. I assume this is normal for a first-gen machine, which are renowned as being very hot runners. What about today's MBPs - particularly the new unibodies. What sort of temps are you getting - say playing back video, etc. What's the maximum?
