Has anyone had a 5970 where one of the vddc phases for a core hits thermal shutdown at less than stock clocks? I'm talking, one phase at 115-120C and all the other phases on the card in the 50s. I remounted the stock HSF twice with new pads each time and I then mounted one of my spare EK waterblocks to the card.
Bottom GPU-Z, VDDC #2 is sitting at 72 Celsius with the core clocked down to 300MHz @ 0.95v just to keep it cool. At 375MHz and 0.95v it hovers around 95 Celsius. This card is at the end of a 6 card serially linked GPU waterblock chain so the incoming water is a bit warm at ~33-34C but compare the top GPU-Z. All my other 5970s look like that, cores in the 40s, VRMs in the low to mid 50s depending on where in the waterloop it sits.
The previous owner sent me a screenshot of the card running 800MHz on the core with an uptime of around 20 days right before he shipped this and another card to me. I trust that the owner didn't do a bait and switch. Just curious if anyone has seen this and if it is a sign that the phase is about to pop or if they've recovered it with something like a bake in the oven.
