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.
Some of my Vegas hover low 50's while a couple are high 60's under full load @1408/1100. Either its silicone lottery or just inferior thermal grease/pads.
