I had a gigabyte 5700 xt gaming oc. The card instantly reached (like 20 seconds) over 105 degrees junction temp if I put it to 100% load. I had RMAd the card for this reason and the replacement that gigabyte gave me is rev 2.0 with higher fan curve yet has the same issue. I've undervolted to 1096 mv (stable) and increased power consumption by 50%. The card stays comparatively cooler but reaches tjunction limit within 1 minute. I don't want to repaste as I've seen this variant running way cooler. What to do?
