I had to test my 5090FE ...
The shitstorm made me paranoid , i had to see for myself.
This is what my temps look likes after 10min of furmark, TDP 575W
Running a 600W 12HPWR cable on my ATX 3.0 enermax PSU.
The cable is 16 awg and is rated for 80°C.
Heat seems to be spread out across all wires except one cable that seem colder on the gpu side ( on the psu side image ,the darker area on the cable are the sensors wire that runs on top)
I stopped after 10min because temperature looked stable.
I think iam still gonna set power limit to maybe 80% for now to be extra carefull.
max TDP was 585.5W , max GPU temp 78
