Hi there,

I recently tried to upgrade my 2016 Macbook Pro 13 to the 2017 Kaby Lake as I needed a bit more performance.

My temperatures on the new model were out of control.

If I ran "yes > /dev/null" in 4 Terminals simultaneously for 5 minutes (for each core and thread) I would see core temperatures as high as 96 Celsisus which is crazy

My older 2016 Core i7 6660U model would never go past 80 Celsius

What temperatures do you get on the Core i5 7360u or the Core i7 7660u models?

You can use iStat menu or Mac Fan Control to measure cpu "core" temperature
 
This is normal as far as I can tell. Check out notebookcheck's review: https://www.notebookcheck.net/Apple...017-i5-without-Touch-Bar-Review.234282.0.html. Scroll down to the temperature section and click on the "stress test windows" picture to maximize it. In it, you will see CPUID monitoring software with the Intel Core i5 temperatures section, at the right is the max temp, which is right about what you are seeing.

FYi, Kaby Lake is commonly documented to run hotter than Skylake on a similar-chip basis.
 
I really don't feel like trying that what my MBP, but - I'll often get temperatures around 65-70C if I have an external 1080p plugged in and having several tabs open (Facebook, twitch, or anything like that). My fans get pretty loud for no apparent reason as well - definitely regret this nTB.

Yes it is a crazy test. What is your point? My m/c gets to CPU of 99-98deg under heavy load - it <does not matter> what the load is.

Oh my m/c is a 2011 MBP. What you are saying is "if I load my m/c up it peaks out at a temperature it is designed to cope with."...???
 
I'm lazy to try LOL

I'm typing on a pillow, streaming youtube and researching garage doors and the fan is silent or off.

Is it really true our fans can go hyper silent and turn off?
 
The macbook pro fans are often turned off depending on the load and some external factors. I have the istat menus and it tells me that my fans are running at 1300rpm (silent can not hear them) Running VLC and Safari.
 
That’s really neat. Kinda quiete like a MacBook but more power when it’s needed
 
mine in normal use the temperatures of cores 1 and 2 is about 40 celsius.
while I convert a video it also reaches 93 celsius.

with connected power supply the fans start at about 60 degrees.
without the fans start at around 70 degrees, before rpm 0

confirmed?
