Fan runs full speed randomly while sleeping(2018 13 MBP, Mantiz Venus)
It happens on my 2016 15" Macbook Pro as well, makes me almost impossible me to sleep while Macbook's asleep.
There is no problem on bookcamp.
I suspected 'power nap' or 'lan wakeup' feature and turned it off, but it still frequently wakes up and makes my Vega64 fan run in max rpm, needless to say backlight of my keyboard brightens entire room.
So I'm using caffein to keep awake. Problem is when I leave it on and turn back the monitor on in the morning , bluetooth is going something wrong.
I had this issue too, I removed the option to make the Mac sleep. I'm testing Mojave now I will report on this issue (it seems gone) but I noticed during sleep and probably interrupting it, macOS continue to switch from ethernet to Wi-Fi
We had detected the issue and Intel will release a Signed FW to us soon. It is one of the FW behavior in MBP 2018.
This happens on my 2016 15" MBP as well. GPU fans silent until sleep, then full speed until woken up. Once this has happened the fans will cycle between silent and 20-30% (no load) until eGPU is ejected and reconnected.
@mymantiz_john - Any word on the FW update for this problem?
Still have this problem with the newest Mantiz Saturn Pro (with RX 580 and 2019 MBP 16'') unfortunately. Guess the only solution for the time being is to unplug the eGPU every night, otherwise I won't be able to fall asleep 😛
