So i got my new 3090 ftw3 ultra after my first one died instantly to new world.
I installed it. Followed the instructions by amazon , fps cap and all.
Game ran. For 30 mins. Then went black and fans ramped 100%.
Card didnt die though. But it has done it a couple of time within 5 mins now
So im worried my card is damaged.

Both cards were 0.1 revisions.

How do i contact evga in australia to deal with this ?

Is it worth trying to get a rev 1.0 ?

My supplier is telling me there isnt anything wrong with the card. And they have no knowledge or choose to deny that the cards have faults.
Power cycling and fans doing their own thing other than the fan curves i set . Is a sure sign something is wrong to me. Im more worried about long term damage.
As i also use this for workloads.
