I've run into a bit of a weird issue, curious to see if anyone else has experienced this. When playing back flash content, on my 17 in 2009 MBP, I'll see temps of around 70-75 Celsius, whereas, on the family imac(which is much older by the way, back when plastic was still being used instead of aluminum), temps will stay cool, usually around 50-55 Celsius. I've determined that using Chrome is partly responsible, but there's still a significant difference even when Flash is used in another browser. Strangely enough, running Flash, no matter the browser, is fine on the Imac. Any ideas? To be fair, I haven't been using the MPB as much since I've spent a lot of time at home over the past few months(the imac has a bigger screen), so maybe its just dust? I'm almost certain that this wasn't happening before when I first got the MBP. They're both setup the same with all the latest updates applied to both the OS and Flash Player.
