Are people improperly connecting them again?
The problem seems to be load balancing, or lack thereof. A German guy on YouTube noticed that his cable got up to 150°C at the PSU end, due to one wire delivering 20 or 22 amps, while the others were getting a lot less pumped through them. 22 Ampere is pretty much half the power draw of the card, through one wire instead of three if the load was properly balanced between them. That's why it ran so hot and melted to shit.
If you've ever worked on your car's 12 V electrics system, you'll know how thick the wires (and corresponding connector sizes) are for things like window defrosters that will run through a 20 or 30 amp fuse.
You probably mean der8auer?
Right.
