UPDATE: If you are using GELID EXTREME PADS see below
Pads need to be 2mm on the die side for the Evga 3090Ti cards and 3mm on the backplate are perfect, it would of been nice if Evga still sold the stock pads but the GELID EXTREME pads in 2mm and 3mm are all you need. Hope this helps someone else looking to repad their card.
