Razer Core X Chroma - Can anyone confirm if the PSU fan is always on?
@tonyvee thanks for DMing me more info and tests on your eGPU set up. It's good that users share their experiences so we can help others.
After two weeks of testing and studying many user posts, I have noticed that some Radeon RX Vega with Revision ID 0x00c0 have stability problems and video bugs. If you bought a used card that was firmware modded or used for mining then that would exacerbate the problem.
RX Vega with Revision ID 0x00c1 have a much better experience. Therefore I have refunded my Vega 64 with Revision 0x00c0.
I'll now purchase the Radeon VII but will first wait for the fan fix and for Apple to list it in their support article.
