How are you guys getting sub 50C temps hashing 2k on Vega 56s? Are you blowing freezing air on them or something? I'm at 68-70C doing 2k at room temperature and with a 120mm 5 fan array cooling.
http://i64.tinypic.com/mc9o5l.jpg6 card rig with about 10cm spaces with fans ~1800rpm and no additional cooling. No problems keeping it under 60 at ambient about ~19-20c.
This rig pulls between 950-1050watts from the wall. If you are having temp problems your under volt probably is'nt working because @ 150W per card the temps should'nt be a problem.
