EVGA 30 Series Cards in eGPU: GPU fans at max speen when connected laptop is asleep or off
I have a Razer Core X with a Razer Blade Stealth. I just upgraded from an Nvidia FE 2070 Super to the EVGA 3090 XC3 Ultra Gaming. I purchased the card to speed up my research (deep learning + genomics).
The issue is as follows: when the laptop is asleep, hibernated, or off and it is connected to a powered Razer Core X, 2 of the 3 EVGA GPU fans run at max speed (annoying for me, terrifying for my cats). Unplugging the laptop stops the spinning GPU fans, but remains an inconvenient workaround as the Razer Core X is my primary method for charging my laptop. I have updated Nvidia drivers, bios, and the cards firmware via the Precision application, but nothing has helped. I have tested both Windows and Linux sleeping situations. As the problem is specific to the EVGA card, I am assuming it is an EVGA Thunderbolt firmware issue.
@drsteve, I had the exact problem with a Gigabyte card a while back. You are correct that it is a GPU specific problem. I did a bit of research and found some people fixed it by disabling fast-startup in Windows, but for people like myself I had to change GPU to stop the issue.

Thanks @boltoway. Given the speed gains, I will probably just keep the card and deal with the annoyance until I can replace it. I posted on EVGA forums and hope its something that can be resolved with a firmware update.
