Macbook Pro overheating while using Logic


I've been experiencing a problem with my 15" i7 Macbook Pro and Logic Pro.

Often, while I'm working on large sessions in Logic Pro, the fan will just start getting really loud. Sometimes, after I've been working for a while, it doesn't ever slow down and I have to quit Logic and give my machine a "breather."

It ALWAYS happens when I SAVE a large session as a new session. This doesn't seem stable to me, and I never had this problem on an older Macbook Pro.

I haven't found any real discussion on this, other than general issues people are having saying that the newer Macbook Pros overheat a lot easier.

Is anyone else experiencing this while using Logic?

Macbook Pro 2 GHz Intel Core i7
OSX 10.6.8
Logic Pro 9.1.5
