The argument that the heatsink was not making good contact with the hexfets... Look at the thread in the Chinese forum. There are more pics. You can clearly see the indentation of the hexfet on the thermal tape. It WAS making excellent contact. I would have gotten rid of the tape alltogether and used paste plus small bolts instead of spring clips, but it still shouldn't burn up in flames like that.

Even cheap MOSFETS just pop and die when they fail. This thing was literally starting to ignite.
Can you show or tell us proof as to why this is a cheap IC manufacturer?
I'm going to give you the benefit of the doubt, but I'd like more information. This is I think the third post I've seen about GB X79 boards catching fire. (One of them did it instantly after power on).
