My wife has a MBP 2.4ghz core i5. She has Sims 3 and all the expansion packs. She uses the architectural features to build towns and houses,etc. Well it makes a steady fan noise after a while(she plays for a few hours straight). I checked the istat widget and its at 5998 rpm and 164 F with a noticeable fan noise. Not as loud as windows laptops that I can remember but loud enough to notice. Is this normal? The machine is only 2 months old. It works great and only does this when she plays Sims3(the only gaming we do on it). Any thoughts or suggestions? Thanks for the help and Happy Thanksgiving.
