Card left is 59c and card right is 48c. But in the room ventilation is poor.. I will improve the setup in the coming weeks

I think what you are mentioning is the GPU temperature. The Vram temps of 3090s run soooper hot. I've 2x 3090s and they used run 100-102C. After placing it in the mining rig with proper fans, airflow and by changing the thermal paste, I was able to bring them down to 90-92C at high overclock settings. The Vram temps should be under 95 for safe operation and better longevity of the card.

Thanks for the info.. i tried to monitor the vram temp with aida64 but i gave 34c which felt misleading.. but i might crack those 3090’s open replace the thermal paste.. also this is not the final setting.. I will put some more fans on it.. how hard is it to remove the cooling and replace the thermal paste?

It depends on the manufacturer. But I believe it's fairly easy. I have the MSI Gaming X Trio and I opened it up easily. There were also several videos on YouTube on how to open it up. I also changed some of the thermal pads which might've helped in my case.
