The 3090 and 3080 are massive heaters because they have some GDDR6X memory on core sideThat happens as even though GPU's get more efficient they are smaller so less area to transfer heat to a lump of metal, and at the end of the day the actual Core temp matters more than the heat out the rear (I have never had a PC actually heat my room in the winter).
you can easily shave 20 C by changing the thermal pads from the memory temperature.
the card can be sometimes limited by the throttling of GDDR6X.
Usually the memory on the backplate side does not get cooled down that well in most of the cards I have examined.
Even sticking fins with the adhesive heatsinks on the backplate for the cards that come with one will massively decrease the memory temperature of GDDR6X
