    I really hope there is some type of software update that will address this. My 2018 MacBook Pro just seems like it constantly runs hot when I put it through any type of moderately intensive task. Editing and converting video makes this thing blazing hot. These are tasks that my 2014 could do (albeit much slower) but at not nearly the amount of heat generated.

    I have grown to really love this machine but the heat is a constant issue. I actually use my laptop on my lap (shocking I know Apple) and you can't have your machines run this hot where it makes your users uncomfortable and breaking out into a sweat. I don't have a reference point as I haven't used a windows computer for anything besides work email in years, so maybe that's just how these thin machines run now. I hope a fix for this is in the works though. If the heat issue wasn't so bad this would be the most perfect laptop I've ever owned.

    This is pretty much the story of the 8th gen CPU’s (6 core 15”, 4 core 13”). If coolness is a priority, maybe the Air would fair better (of course at a performance loss, and a few other bits).

    Yep, high performance in a small package welcomes heat, a rigid laptop pad like the Targus chill mat might help keep things cool. I'm trying to locate a portable pad that will fit into my briefcase for when I receive my new MBP.

    I would not say so about the 13". My 4 core 13" is very cool, while the 6 core 15" is very hot. Others report he same. Maybe because of the integrated GPU?

    I use the BookArc.

    We suffered the lack of progress in PowerPC and now we suffer the lack of progress in x86. Intel are adding more cores but this is just creating more heat and they are not able to move to 7nm yet. Even at 7nm they will keep increasing clockspeed and cores and the heat problem will remain.

    Desktop Macs can keep x86. Mobile Macs must have Apple Ax Series. Imagine the possibilities. Fanless designs and all day battery life with incredible performance. For more performance we add eGPU.

    It would be great if we could enable / disable CPU cores on demand to optimize heat and battery usage.

    Doable via XCode's Instruments.

    Thanks! I thought this was no longer available on newer MacOS versions and newer hardware?

    If it isn't I'm not aware of it. Then again, wouldn't be surprising given Apple's recent track record of playing nanny. There're some helpful apps like AppPolice and App Tamer but for my usage case Instruments does the job just fine.
