The partly melted thing in this picture is a mosfet and what you should be checking the temps of. If it doesn't have a heatsink, stop using the card until you get some on it.
These are the areas too hot to touch for me. I circled it green. I only touched the plate. Probe location is in between there in red circle.
The VRM when I touched it was scorching hot too. Didn't put a probe on it to know how hot.
