Cooling was not one of the weak points of Ada cards. I don't know how will Nvidia improve it or how much do they expect the 5090/5080 cards to use to need a new design.
Regarding the Zen5 lineup leak, it's a bit disappointing the small-ish 10% improvement, at least on Cinebench 23. I also find it curious how the desktop parts are the only ones with no AI accelerator part in them.
