Yep. That's kind of what TechPowerUp was alluding to. Sure the solution from ASUS worked but they had to crank the fans to keep the card in line and it got loud.
I really wanted to get an AIB LC card with the 3090s but I simply could not find one that had a custom PCB that would allow for increased TDP. They mostly were all reference design boards which, while nice, may not have let me fully crank the core to it's highest potential. Since I do have a Strix OC 3090 I did see that both EKWB and Blyski both made full blocks for it and that would've been really cool but by the time I created the full custom loop I was looking at around $1K+ to get up and rolling.
I'm hoping that when the 4090s rollout that some AIB will release one with a custom PCB and LC so I'll have some more options. It'd be nice if all I had to do was disconnect their radiator and connect the lines to a custom loop.
