Please, don't talk about things you don't know about. I'd know, I'm extremely guilty of that as well.

You know CHiL? The voltage controller used on all of AMD/NVIDIA's reference boards? Yeah, they got bought out by IR a long time ago. Gigabyte has used IR for a long, long time on their boards.

Have you tested all the top models of each manufacturer's boards to find these "NIKOS" Power MOSFETs? No?...didn't think so.

The problem here is not the MOSFET. It is the OCP and OTP circuits to blame. The board should throttle the CPU or even simply shut down when the VRM section gets too hot. This board didn't shut down until it caught fire.
Actually in this instance it was the fet that was to blame. It was a faulty fet, they happen.

It would be nice to have a VRM measuring system that actually worked though. None that I am aware of monitor each fet/driver IC and only measure PCB or heatsink temperatures at the most with reference to temperature. Bad fets often enter thermal cascade long before the PCB or heatsink temperatures reach the thermal tripping point.
