Unibody macbook pro: 2.53 gHz 4GB memory 320 gb HD Settings: Better battery life option enabled, therefore using the 9400 M I had iStat record over 100 degree tempshttp://images.macrumors.com/vb/images/smilies/eek.gif while using Handbrake last night. Mine has always seemed hotter when running comparable applications with my friend, who has the same model/specs. My fan speeds later increased, but the temp only decreased to 98 degrees celsius AT TIME OF SHOT, TEMPS MEASURED IN FAHRENHEIT! The attachment is a close-up. THANK YOU!
