Hi,

I was thinking about purchasing the 2018 13 inch MacBook Pro notebook and would like to know if the two fans in this notebook keep it cooler as compared to the 2017 MacBook Pro model without the Touch Bar (which has one fan).

Thanks in advance for your help!

Not necessarily, the CPU in the 2017 nTB is rated at 15W, while the 2018 TB is at 28W, so we roughly have a x2 heat efficiency needed to cool the TB CPU down alone, incidentally proportional to having x2 number of fans.

I'm not sure but don't they have two different cooling systems (I'm not sure but I also think the 13 inchTB version's cooling system is similar to the 15 inch model).

Thanks everyone for your replies! I basically wanted to find out if the RMBP 2018 stays cool for the most part (doesn’t overheat) as I had a RMBP 2016 (the non-touchbar version) & it really got hot.

It never overheats, unless you have an erroneous definition of "overheating" to mean "the laptop feels warm from the outside", then yes it does "overheat"

It doesn’t overheat. But as mentioned above, these CPUs are rated to run at 100C, which they do - under load. The cooling system is indeed better, but it’s used to deliver higher performance rather then lower temperatures.

Encoding a video file it will get quite hot to the touch, and the fans start pumping a lot of hot air very quickly. According to powergadget the CPU temp settles in around 90° with the processor still over 3.0ghz, so no I would not say it’s “overheating”.
