Those did not originally have a heat sink. The discoloring is concerning but looks like it might be coming from somewhere under them. As I see some of that same color on your 5v regulator and that ceramic resistor there. Speaking of which those can also put out a lot of heat.
Quoted from Neal_W:The discoloring is light brown. Probably just dust collecting there, like coating the connectors above that area as the heated air circulates. See if it wipes off.
Good observation. The build up on the wires does look like the same color. Built up dust can also produce an odor when heated.
I would still prepare for rebuilding the power supply in the future though. WPC systems are near or maybe even past the rated lifespan of many of those components.
