This shows where the Asrock X299 steel legend motherboard failed.  The i9-10980 CPU ran for ten hours then hung.  I power cycled the machine and smoke came out.  Here is where it originated from, the backside of the motherboard under the cooler backplate.  The name goes on before the quality goes in.

Asrock X299 Steel Legend solder back side by cooler backplate.  Quality solder job went up in smoke.

Piece of Shit
