When playing a graphically intensive game, my GPU reaches around 80 degrees and then for 5 seconds it ramps up to above 100% fan speed (the limit i can set is 3000rpm and it sets it to just under 4000) and then stops again. This also usually does not cool the card down much, if at all. The card I have is a Gigabyte 2070 super with 3 fans I have had for around 2 years. This issue never used to happen (whether it never used to get that hot or that it never happened when it reached that temperature I'm not sure).
