The MBP has more vents and improved in design solving some heat issues... The MB does not show that... or at least as far as I can see, it is exactly the same design...
See my post #11 in the brand new
Got your C2D macbook??? thread. Right now after previous stress on the system and return back to iddle for the last 15 minutes, temperature does not drop under 60C... Normally if I do not stress the system it will run at 51C... If used over a couple hours, average around 58... max temperature is at 72 so far, minimum at start was at 46... What do I mean by stress - very minimum - parallels, photoshop, and word, which for this processor should not be out of this world...
So, heat issue is not really there - the solution for it is bad... The way they dropped temperature was by making the fans run all the time... and really go in maximum boost at higher temperatures...
It sounds like I'm complaining here, but all I'm trying to do is figure if I can work with this... I do not have a choice, I want OS X and a small form factor. I wish they would have a 12"MBP or at least morse code vents around the system... whatever to actually decrease temperature by engineering design not by firmware...
