GPU is undervolted, fan curved is untouched
Core clocks don't hold to 1340MHz as they should, temperature goes up to 85 degrees C, it started about a month, but since i only used AAA games to test GPU stability, it is stable. This problem is especially visible in The Witcher 3 where fps can drop even down to 40 while before they didn't drop below 60, everything is on uber, hairworks off
I just want to add that in light games like LoL or Warframe (it is light compared to AAA games) core clocks are holding those 1340MHz
