Thank man! Unfortunately until first week of Nov I won't really be able to mess around with the card. Found a waterblock for the card on Ali Express, as I understand they are super rare. Guess I better just buy it as there are only 5 remaining in stock. But to truly max out this card's ability, it needs water. On air I'm able to push 700-800w max before temps become insane. The other thing I've found is the memory temps, even at stock are pretty terrible at around 74-78c. When I push the card they can hit 84c. The cooler itself though can manage to keep 700-800w in check with core temps in 70s, which for an air cooler with vapor chamber is decent at that power draw. I think my TUF OC 5090 card hits around 70s at 600w.
They used this *mostly* closed off backplate, and ZERO thermal pads. Instead it has a heat shield? So it essentially traps heats in to the card. Makes no sense. I should probably remove the shield and do thermal pads to try and wick heat off the back of the card.
The card did have PTM, I took it apart to PTM the card, and to my surprise, it already had PTM lol. But the tinkering let me take it apart, which thankfully is quite easy and they use same size screws for everything on the back. The VRM is just ridiculous on the card. 36 phase VRM.
