My setup: 2018 MBP 13''(High Sierra, 8th gen Intel) + Mantiz Venus +Gigabyte RX 580 Aorus 8GB + Acer X34 + Dell U2717D.
Everything works perfectly fine no matter lid of MBP is shut or not. But when it goes to sleep, GPU fan would randomly crank up to max briefly for 1-3 seconds before going complete silent again. This happens every 10-20 minutes while sleeping. 
After some search, the only thing I can find is this: https://www.reddit.com/r/eGPU/comments/8708b2/aorus_gaming_box_1080_loud_when_laptop_sleeping/
Just wondering if anyone having this issue with Mac as well? If so, is there any solution apart from unplugging every time?

Here is a short video I managed to record to demonstrate the issue:

This may relate to macOS sleep behavior. I noticed this same fan running issue when the Mac was asleep too. It was the same for both external GPU and internal GPU with a Mac Pro tower.

According to the FW from the MBP, it is required to have certain standby power ( even your battery had been fully charged ). it is about 23W, if your battery is less than 80%, it will start to charge with total power consumption 107W. ( 87W PD to laptop ) when the laptop is under charging, the TI65983 PD controller is quite hot, system needs to spin to solve the thermal issue.

Battery was fully charged in all these tests.

I am facing the same issues on my 2018 13" MacBook. My battery is fully charged. If the issue is the PD controller getting hot, why didn't Mantiz place a cheap heatsink on the chip in factory? This makes leaving the MacBook plugged in almost impossible, because the fans spin up loudly almost every minute.

Edit: In bootcamp, this behavior is not exhibited. Nevertheless, in a product intended to work with Macs (going so far as to match its color schemes), measures should have been taken to ensure proper function.

Edit 2: I very much doubt the TI65983 is the issue. I set up a computer fan to blow directly towards the controller while the Mac was asleep, and still experienced the same issue. Could this be due to the T2 controller in the 2018 Pros? I've heard of a similar issue with the iMac Pro which has the same T2 controller.

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.

I basically have the same issue. My configuration consists of a Mantiz Venus with a Sapphire Vega 56 Pulse in it.

During macOS sleep, the Graphics Card fans will randomly start for half a second every few seconds, and then stop again.
The Mantiz Venus case fan is running permanently during sleep, which is not great but I could live with that. The GPU fan cycling issue is really annoying though.

I tried this with two different macs to rule out the notebook itself:

  • MacBook Pro 2018 15" with macOS 10.14.0 beta 11 (Mojave)
  • MacBook Pro 2015 15" with macOS 10.13.6 (High Sierra)

@mymantiz_john will this issue be resolved with the upcoming firmware mentioned by you?

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.

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?
