I saw that picture and thought that you were messing around... You were really serious! HAHA. How could you know enough to buy a 2080, but not to buy a new case with better airflow?
Never had a heat problem with the last 5 video cards over the 12 years or so. For my part, Just lack of research on the 2800 I guess? No biggie, it'll all be good (I hope) when my new case gets here.
On another random thought, somebody had mentioned the room temperature needing to be cool too? I think if the day comes that we also need our house air conditioned to stop video cards from burning out we'll have reached a high level of insanity 
Room temperature will increase the temperature of the card by 1 degree for every 1 degree of ambient temperature. You simply can't cool a card on air lower than the room temperature. In most cases, this means a slight increase with an increase in room temps. If you are comfortable in your home, your card is probably fine with adequate case cooling. The bigger issue here, is that you have a card that is producing a lot of heat and dumping it into the case and that heat cannot escape. The heat builds up in the case and so does the temperature of your card.
What kind of cooling do you have on your CPU? I noticed, in your previous post, that your CPU temps are not moving much with the side off.
EDIT: I just noticed this in your previous post: "Temp in my room is about 60 degrees f, (It's winter here in the mountains)"... That is one cold room, your room temp is NOT the issue here.
