    Just curious, are you guys using anything to control the fan speed yourselves? I notice my fans always run at min speed and my temps go from 70-75C on my CPU....the outside of my case just above the keyboard get pretty hot.

    That's a perfectly fine temperature. Increasing fan speed would just decrease battery life. The CPU is rated for 100C.

    When do the fans ramp up with the auto control?

    That depends on many factors. But if needed, the auto system can go above even what the SMC reports as maximum fan speed, so if you use a tool like SMC Fan Control or Macs Fan Control to control fan speeds, you may actually limit the cooling inadvertently.

    I am just now reading about Chrome on Mac....maybe this is the heat up problem =(

    I never knew it was so bad to run chrome on a Mac, been doing it a while.

    Well, wouldn't you know it....its true how much Chrome eats your battery and heats up the machine. I thought it was the hardware acceleration setting, but that doesn't seem to be the case. Just running chrome cost me over an hour battery time (according to activity monitor). Noticed a temp drop of about 20 DEGREES!! Sitting right now at 50-55C from 70-75C. WOW! I can not believe how much of a difference this is.

    Chrome has always been inefficient, but it's the same on Windows. Compared Edge to Chrome on Windows and you'll see a similar trend, although Edge isn't as efficient as Safari either.
    But as I said, your temperatures weren't in the danger zone - Hardware will run hotter when you push it a bit, and there's a lot more software than Chrome that'll run your hardware harder. Safari is just very efficient. Though it should be noted that it doesn't support as many of the newer web technologies as Chrome - albeit far enough to most web sites
