i got 110Mh but with 90c vram temp is that ok for 24/7 mining
maybe
I do 87-88 5 months so far. So in theory you could be good. Or not.
I would shoot for under 90c
But 90c is under the 95c throttle point.
My 3090 are good in the minerdude cases due to powerful 140mm fans in it.

Frankly I do not rush to get 3090 cards
I alternate the in the 12 card cases six or 7 cards max.
I run them at 275-290 watts
But they are not ideal cards.
I could get them right now at newegg

price is too high at 3000 a card
