Looks like Apple uses WAY too much Thermal grease on the new MacBook Pros. This guy took his apart and reapplied correctly and saw an 11deg difference! If you know someone with a MacBook pro, I would recommend they read this!

It just takes a slight misapplication of thermal grease on a MacBook Pro to make the temperatures skyrocket. After reapplying thermal grease properly, the fans actually turn on and keep the system much cooler, to the point that pg. 107 in the MacBook manual becomes unneccesary. They don’t even get loud (unless you’re running over about 65% processor usage, in my case). Apple seriously fucked this up, and it’s relatively simple to fix and prevent. I sit with this thing on my lap all the time now, and while it gets warm (I expect it to), it’s not uncomfortable.
