MBP 2018 gets extremely hot while backup

[randomberlinguy]

Hey there,

today I did the first backup on my 15" (i7) MBP 2018. I connected a new Samsung T5 SSD via USB-C Port and started the back with time machine.

After a few moments the MBP started to get extreme hot even the keyboard keys got warm. The CPU was used by just 50%. There was no App running in background.

The MBP is on the latest MacOS Version.

Did someone experienced the same?

Same problem here on High Sierra 10.13.6. I have a 2018 13" (i7) 2018 MBP and have TimeMachine on a NAS. Laptop gets hot and fans kick on whenever TM runs.

What temps are you seeing?

I reproduced it will a full backup. The peak I've seen was 81°C for the CPU cores.
Later on I'll try to reproduce it with an other device.

That's normal, especially if you have a six core CPU copying at high speed.

We used to have temps higher than that when we had one core and only a slow cranky hard drive.

You may be able to manage the temps a bit better by throttling the computer using the Volta app. I use that and I'm enjoying cooler temps.

Thanks for your advices.

Yeah, I intend to use volta or similar to manually set much lower power limits when I don't need it to keep temps down.
Once I actually /have/ a laptop again...
