When I run e.g. world of warcraft on my new 2011 macbook pro 15" with 2,2 GHz i7 processor the computer gets VERY hot and the fan becomes VERY noisy. Even if I use the same low video settings as I use on my girlfriends old MBP the fan goes crazy. Strangely my girlfriends MBP doesn't make a noise??? So even though I've got a fancy sandy-bridge-whatever processor my computer gets hot and noisy while the old MPB doesn't. Well, isn't that money well spent?
