Both my 1080 are running between 1999 & 2088 with temp 76C to 78C
When they are pushing 2025 I have seen temps hit 80C - 82C
I have XOC running at 124% and set priority to Temps and set the Temps to 86C.
So for no issues with some GPU Overclocking and No Over Voltage and No vRam Overclocking
PS I added two more guns
My HFM for overnight runs only.
