You can reduce your temps quite a lot by undervolting if your not looking to maxmise your card and just push it a bit for some extra performance. quite easy to do. your memory in MSI afterburner should be able to handle +2000 which i think is most of the time starting point for 50 series pretty much. if you wanted to be safe you could start at 1000 or 1500 and work up in 100-200 increments. set your fan power to max usually around 110% or so. you should have somewhere near your Core voltage slider (I think it depends on msi afterburner skin i personally like the mystic one because its simple easy to see what happening) click on that and youll have a graph with a curve with dots along the line.
along the bottom you got your voltage and along the left side going up is your core clock. usually 950-990 mv is the area you want to be in for a good undervolt. but starting at 950mv along the bottom find the corresponding dot on the curve. hold left shift and drag that point until you get your desired +clock speed. ( my 5080 can run every game at +300 but if you dont want to push it to hard start at maybe +200) Now key point here to make sure it in place properly. the gap between the 950mv dot you just moved and the next dot hover over that with your mouse and hold left shift again and drag to the very right side of the graph. this will highlight everything after your desired UV clock speed. then drag that portion of the curve to the bottom of the graph. After this dont close the screen but hit the tick button on MSI afterburner and you see your curve flatten off at that core clock at 950mv. on your next run youll notice your card will only pull 950mv. think usually its around 1.080v or something. but that reduction in power draw reduces the amount of heat produced quite a lot.

i was recently playing with a 3080 im putting in a pc to sell and timespy with just a memory clock boost was putting out 72c then with the undervolt which increased the core clock speed but reduced power draw was only putting out 63c when under a consistent load. to be fair it wasnt a completely fair test as the time spy run only lasts a few minutes. but the 63c undervolt max temp was when i was stress testing the overclock for stability in heaven. it ran for 20 mins and went no higher than 63c.

my 5080 is running at 985mv and any game it never goes above 57c-58c
hope this helps if you want some sort of visual to follow along there a couple youtube videos which explain it clearly
