Since the first post needs confirmation about Zotac AMP HOLO, I wanted to share my experience.
I've been running my first 3080 for about one and half day in my server case which has very good cooling (5 intake, 5 exhaust fans, all Arctic F12 PWM, running at full speed).
OC settings: FAN 80%, PL 230W, CORE -200, Memory 2400. Ambient temperature around 20 C, Core Temp 56 C and that baby gives me 99,3 mh stable.
I'll keep you guys updated if I get it throttled after a week or so just like ventus cards.
Ventus cards throttle after days of being stable ?
I've read that from the discussion below. I'm afraid I will have to consider applying those sweet thermal pads from Grizzly one day.
