New MacBook Pro Is Cooler Than Previous One. No, Really.

Jason O'Grady over at The Apple Core has taken some serious measurements concerning something I had noticed as well. When I took my first MacBook Pro out for a run -- a 17-inch with an Intel Core Duo -- I noticed it was running somewhat hot, hotter in fact than my older PowerBook. But then once Apple swapped out the Core Duo for the higher-performance Core 2 Duo the outer temperatures seemed to be less. It was just a little difference I noticed, but which I didn't think much about.

It seems I wasn't too far off the mark. O'Grady took temperatures on both MacBook Pros and found the newer appears to run much cooler than the older one. The newer, high-performance machine actually runs as much as 21 degrees F cooler than its predecessor. More here.

My first though was that it gives proof to that old rule of thumb about buying Macs: Never buy the first generation of anything. Charles Jade at Infinite Loop seems to agree.
