How do the temps run with these, it doesn't appear that you would watercool it (or maybe yes?). I liked looking at the ASROCK RACK 3U8G-C612 manual where it talked about air flow, it never really talks of max temp, although it lists these cards as part of its QVL (Qualified Vendors List):The ASROCK RACK 3U8G-C612 8-WAY GPU SERVER reminds me a lot of my eight GPU Tyan server, except all of my GPUs in the old Tyan are in the rear.
