I did some research on this some time ago; according to sources I found (both online and talking to Apple reps) the MBP is made to run hot -- upwards of 150ºF (65ºC) or so. My MBP runs around 120 to 140 ºF (50 to 65ºC) most days. I have a little Vornado fan on the end of the desk that I keep on most of the workday to keep it cooler than that. You're right, though; 75ºC (about 167ºF) seems excessive, especially if it's constant.

Here's a link the Apple Genius at the Plano TX store sent me: http://www.cartoonbarry.com/2007/05/macb...e_hot.html
Also, and this one perplexed me something mighty: fire up Activity Monitor and check to see if something is running the CPU at or near 100%. I have, on three separate occasions, had a document stuck in a printer spool. This was running the CPU at 100% (or near it) and, of course, was heating it up. A force-quit of the print spool might help, but the fix is to open the print monitor and delete the offending file.
(I discovered this on a blog a few years ago; I can't find the link now but I'll look and see & will post if I find it.)
