They pretty much all have, some have really good cooling systems.
For example this is the stock 3080:
This is the one i got TUF OC: Which i bought through its review as its a super cool / quit card.
It's easy to see why that is. ( 3 fans on top )
While the 3080 FE sits at 78-80c core temp, the tuf sits at 60-65c, huge difference.
V-ram wise its 105c on FE edition, and on asus FE edition its 75-80c.
Now this doesn't seem for the core to be bad at first sight with the FE model, but it actually is as those ampere cards are extremely sensitive to high C for clock speeds. The TUF will easily boost to 2100 mhz at times, while the 3080 has issue's hitting 1900.
Besides being slower u also get performance issue's this way. Specially on the memory, because the memory will error out. This is why nvidia couldn't care to cool them properly it seems like because there was no way for those modules to fail. The memory auto corrects errors which means it will simple render it double. Which will create microstutter through delay or other problems like low fps tanking at times. RDR2 benchmark is a good example here, where if you turn around u can see low fps suddently happening that u can't explain.
The 3080ti is even worse because they just slammed that 3080 cooler on a 3090 core.
