... and yes I know.. the watercooling solution for three Ultras is far away from optimal. I just got the Stealth-blocks, used some parts I had in my office and got them up and running. Too bad it is not so cold and no snow/ice here in Finland where I live so I couldn't take an advantage of it. Rivatuner reports GPU temperature 54 Celcius and the reservoir feels warm. I do have couple of aces in my sleeve reserved for the gfx cooling so stay tuned
