Just received my unit. There is no any backside VRM heatsink on my RTX 2080 but it should be! It's impossible to use video card without it. How can I get it?!
Some users have same bad experience when they get their 2080 without VRM radiator. Mosfets will burn out without radiator - 100%.
Another bad news is that Dell support does not know about this radiator, they cant find it. I found similar case where the buyer still got the radiator He says that radiators part number is 2WYX4 or P92K8
VRM radiator is on backside of video card. You must take it off and look at its back. Why they does not put mosfets on face side and make them contact with heat pipes for any chance for heat transferring away - I have no idea.
Even existing radiator not giving you 100% guarantee for non burned mosfets cause of low possibilities of heat transfer from it
