I've been playing games like HL2, CoD4, etc. on my MBP and it gets pretty hot. Fans spin up really loud, which is annoying. It doesn't overheat, it's just loud. I also want to start running some distributed computing like Folding@home on it, which would cause the fans to be 100% all the time. I am looking for some kind of laptop cooler, and I'd like to know which ones people have had experiences with and if there are ones I should stay away from. What do you recommend? Do these things even work?
