I decided to add this to a new thread as I believe it needs more attention then current threads about the NVIDIA issues. So please, mods, keep it a separate thread. I bought a new Macbook 15" on Monday and from the start I noticed it was running a lot hotter then my Notebook with similar specs with the same GPU. I carried on using it all the same, after World of Warcraft had finished installing I booted it up, I heard no fans and it got so hot I had to turn WoW off and place the Macbook Pro down on something else then my lap. I knew this wasn't right and I knew that my Macbook's life would be seriously affected if it gets that hot so fast. So, I took to the web to find a fan controller and I came across smcFanControl 2. I have been experimenting with it all week and I have found some great settings that keep the Macbook cool and barely warm when gaming. The whole system barely hits 66c when gaming on WoW for a few hours. If anyone is interested you can download smcFanControl 2 from here and here are my settings and custom profiles I made for it: Default: 2000RPM (Apple's Stock Setting) Games: 5500RPM (It's louder than normal but with sound coming from the speakers you barely hear it) AC-Power: 3800RPM Battery: 2850RPM Maximum: 6000RPM (Obviously, Maxed out) The routine I use is to turn the Games profile on before I start a game, start the game and when I am done with the game, close it, turn on maximum for 5 minutes then back down to Battery if on Battery or AC-Power if I am not. I believe this will help with the situation and I have all faith in this just been a fan issue with them not coming on fast enough or at all. I also have faith in Apple, in-fact I just got an Airport Extreme and iPod touch as I am so pleased with my Macbook Pro. Give it a shot and let me know what you think. Additional Info: You may wish to turn the following on in smcFanControl 2.
