Fanless World of Warcraft?

The game is both very CPU and GPU intensive. Both chips heat up quite a bit during the game. I'm not sure that you can throttle it back to the point where it uses little enough of either resource to not require the fan.

The fan turns on quite specifically in response to the temperature measured within the case. You can reduce the frequency with which it comes on and the intensity by using your laptop in a cooler and well-ventilated location. Other than than, there's not too much you can do. When it's hot, it's hot.

you can also limit the FPS of WoW with the command "/console maxfps #" typed into your chat text while during gameplay, where # is you desired fps. WoW does not automatically govern your fps and will go full tilt unless you turn it down. So on a nice computer you might be getting 150fps which is total overkill and will be getting you computer nice and toasty. try turning it down to a nice, comfortable 40 or 50 fps. i.e. /console maxfps 40

you can use SMCfan control to pull it back but there is a reason the fans are kick on, normaly SMC is used to kick fans up more.

teh fans will create noise but if it is bothering you a lot it could be either a)your rather sensitive/picky (noting wrong with being picky just saying it) of b) the fans could have an issue and be making more noise than they are supposed to.

you could get a laptop cooler board like the notepal, it has fans in it that circulate air under the laptop and it is ran off of usb, my machine rarely runs over 125*F with normal stuff going, if i start doing photos and video or games it may go up to the 150*s but still about 10* cooler than if i didnt have the board
