I just installed a NZXT Kraken G12 on my 2070 Super. When running a Heaven benchmark, the highest I have seen my GPU temps go up to is 62C and idles at 40C. I even set the fan on the G12 that blows air on the VRMs to 100% and it is still throttling. During the benchmarks, my clock speed will hover around 1450 but can drop below 1400. Before I watercooled the card, I experienced no thermal throttling.
