I have the Razer core and used a W5700 and a EVGA 2080 Super. The latter spanked the former when used in bootcamp.I never had this issue even b4 I purchased the eGPU. No fans unless I was playing a game or doing something taxing in Windows under Parallels. It was always connected to an external Dell Monitor via USB C. 5500m and worked without issue. I know people are having this issue, however, I personally did not experience it.
I considered that one but it cost about as much without the 2 Thunderbolt 3 channels, SSD bay and all the USB A and SD slots.
But as someone else said, from my personal experience, the competition is even worse.
Lucky we have Apple Silicon. Very interested to see how the pro machines perform, but as I have also said the current 5600m MBP is excellent if you need windows [and native mac apps].
