    Hi guys,

    I just bought a new 13' MacBook Pro 2018 (16GB Ram) with Touch Bar, and I am a little concerned about cpu temperature. I have read a lot on this topic in the last couple of days, but I am still not sure.

    What I found out is that MacBooks in generell are hot, but usually people state idle temperatures around 45degree C (range of 35 to 50, varies a lot). If I close everything, I might get down to 52, and while browsing I am usually between 55 and 60 (I checkt if there are threads in the background using CPU resources). Watching youtube can get me up to 70 and I just tested Final Cut Pro exporting a 4k Video and that got me temporarily to 97, then thermal throttling and the fans kicked in (which is what I expect). [Room temp is probably 25 degrees right now].

    I know those temperatures don't harm the CPU in short-term, and I trust Apple on heat handling. But I just want to be sure that there is no hardware issue with my new 2500€ machine.... (idk something wrong with the thermal paste,...)

    I have to say, the reason I got concerned with temperatures on my Mac in the first place was one of apples "great" features. When I set up my Macbook I imported my 10 000 picture iCloud library. Doing so, your Mac will start analyzing those pictures in the background using a lot of cpu resources and heating up your macbook. Not knowing this, I was very concerned when I started my new macbook and it heating up extremely without any obvious reason. Note: When taking the temperatures above, I always made sure, that no job was performed in the background.

    So, I am not concerned about high temperates when under load, but I am about the mid temperatures. Doesn't it harm all other components (battery, ssd...) and the CPU when in use, being always at least between 55-70 degrees (since app development, browsing and youtube will probably take the most run time of my MacBooks life)?

    I would appreciate any input on this topic!

    have a nice weekend,

    Those temps look pretty normal and you should be fine. Get iStat Menus and that app will report the temps across all of the sensors. I found that while the CPU gets toasty the other components are not impacted and those temps rare relatively cooler.

    "High" idle temperature (60C actually isn't particularly high for a modern CPU) is simply because Apple prioritizes silence over temperature. There's really not much point in cooling your CPU down below this limit; the CPU is specced for a certain temp, so it's designed to handle that if other operational factors also are within spec (voltage, power etc), and 60C is well below this limit.

    You're not going to wear out your CPU. Don't worry about it. :) CPUs are one of the most reliable components in a modern computer.

    Thanks for the replies! :)

    I guess I also don't have to worry about battery temps around 40 when plugged in? :oops:

    Wow glad i found this thread. I had the exact same Mac spec, and funnily was having the exact same issue as you Freddy. I was mid importing icloud photo (60gb), and all i could hear was the fan blasting at max speed. After restarting the laptop, the fan noise was considerably low, but temp remains pretty toasty to touch at the base of the laptop. I use a fan control app to observe the fan speed and cpu temperature. The CPU temp is consistently around high 50C. '

    This "Idle" temp remains the same for the next few days even with just light usage and general browsing. I guess its just how Mac had set the fan vs temp profile, since you are reporting similar numbers.

    It is however quite strange that my older MBP 13 - 2014 runs at about 10C lower on idle typically.... Any thoughts?
