I know that this is an old machine, but even capping FPS @ 30 and running at the lowest settings is giving me heat issues. I use iStat and SMCfancontrol to monitor my temps/fans. I am consistently getting temps of 80C-90C out and about in the world, with temps rarely below 90C while in dungeons. Of course, this keeps my fans almost constantly blasting to cool things down.

Is this typical for my specs, or is there anything that I can do to reduce these temps? I have followed all the steps on the Overheating Troubleshooting guide provided by Blizzard, and have recently opened up my machine to clean things out and lubricate my fans.

Any advice would be greatly appreciated! Thanks.

P.S. I noticed that I could reduce these temps considerably by removing my battery and leaving the AC adapter plugged in during play, but heard that this is not good for the machine due to CPU throttling by the OS. Thoughts on this?
Besides the overheating article, what else have you done? Have you tried to reset your SMC to see if it helps?

Resetting the SMC
I have reset the SMC and PRAM, did everything that was outlined in the article.

I've been playing with the battery removed to keep things cooled down while I figure this out, is there any real reason that I wouldn't want to play with my battery removed? (besides being really careful not to accidentally pull the adapter)
