Extreme temperatures on x299 motherboard VRM in excess of 100c

Pretty scary stuff! 80-90c on the 8 pin CPU PSU cable... "That's probably close to your cable catching fire"
 
Well, it's concerning yes.
Probably the best X299 board will be the OC-Formula. Would be crazy if even that one has issues.
 
Its not even actually close to the temperature of a fet catching fire...or the board delaminating...or anything even remotely bad really unless its for long sustained times.

Fet heatsinks don't work very well in general because you are placing a thermal pad onto a silicon oxide plastic based component that on its own is a terrible conductor of heat. A better design would sink the heat into the board through the copper layers and use micro-vias to the back of the board and integrate a rear mounted heatsink.
