[QUOTE="Randy B. Singer, post: 1916400, member: 190607"] It may be that your model is just simply under-engineered for cooling. That wouldn't surprise me. At times in the past Apple has even flirted with leaving out cooling fans altogether. For instance, not long ago there was a MBA with the same processor as the then-current MBP, but the MBP benchmarked as faster because the MBA had no fan, and so the processor was often engaging in thermal-throttling. What you want, ideally, is for your computer to maintain not just a reasonable maximum temperature, but for it not to undergo a lot of extreme thermal cycling. Having the insides of your computer get really hot, and then cool down quite a bit, over and over, will have all of the solder joints for it's components expand and contract constantly. Eventually one of those solder joints will crack from the cycling. (It will become a "cold joint".) That will result in a nasty computer failure as the component being held in by that solder joint will have a discontinuity, and the problem may be hard to track down. (You find it by looking for a solder joint that is grey, or rough, or which has a noticeable ridge when you run your fingernail over it.) Cold solder joints were common in the old Mac Pluses. The Mac Plus had no cooling fan, and they could get really hot. Especially when they filled up with dust bunnies. I used to fix cold solder joints in Mac Pluses for friends and clients all the time.
