Gigabyte RX470 - 1.8V_POK randomly disappears

[Bozog]

Card works for a short while, then black screens, 1.8V is still present but 1.8V_POK disappears(measured at pin 1 GS7103 1.8V chip) taking PEX and the other rails with it.

Anything else I can look at other than the GS7103 chip? I did try to remove it, but didn't wanna come off with 2 soldering irons or 450°C air I'll have to clear a space for the preheater tomorrow...

Oh I see why it won't come off with 2 soldering irons, it has a pad underneath, doh!

Ok I'm an idiot, 1.8V_POK is being pulled low by a critical temperature fault...apparently my test heatsink isn't big enough, oops
