  2. No / Not hotter than the other models.

    Hello, first time poster here.

    I'm on the fence about getting the i7 MacBook 12" 2017. I plan to max it out to 16GB RAM, but I'm wanting it to be a cool machine (only slightly warm to the touch - below 32C on the palm rest and 35C on the underside, where it would rest on the lap).

    Looking at reviews of the Dell XPS 2-in-1, the i7 model seems much hotter than the i5 model.
    i7 -
    i5 -

    Other laptops using the i7-7Y75 don't seem to be showing as high a temperatures as the XPS 13 2-in-1 though.

    However, looking at the 2016 MacBook models there doesn't seem to be much difference between the different models.

    Does anybody have a i7 or i5 model that they can comment on?
    If anyone has any good educated guesses as well, let me know :)

    I'd like to know what people's experiences are relative to the MacBook running hot -- does it get too warm to use in one's lap or on partly on one's legs when in shorts?!

    They are still m5 and m7 processors, just rebranded by Intel for some reason.

    Although the slightly higher clock rate of the i5, i7 in the macbook will result in more heat development, the system monitors this and lowers power consumption / speed when it reaches certain temperatures.

    Absolutely depends on what your doing with the machine.....
    Normal everyday tasks it's cool and not an issue.

    But, start running some CPU intensive programs or running some hi-Res video for longer periods and it can get pretty warm on the bottom of the machine.
    IMHO the MacBook is not intended for continuous CPU intensive programs. It's a lightweight, small footprint, mobile machine for lighter duty work.

    There are other machines designed for the HD work....

    I don't have the Macbook 12", but an i7 Macbook air 11". If I am doing something, where I want it to stay cool I am using Turbo Boost Switcher.
    Then it can run for hours and still stay cool. E.g. watching a movie in your lap, playing a game etc.

    Only annoyance is to enter password, when you toggle status and after sleep. But I see now that they have a paid version, where that is not needed and some other features. So I might consider buying an license.
