Greetings I believe your temperature is fine and in specification, Gigabyte has about two or three different 2060 super versions, the one you have is the more affordable of what they offer. They deliberately cripple the cards thermal capabilities by installing a 2 fan cooler on the card so they don't compete with the higher tier ones which have a 3 fan cooler design and a higher boost clock. If they did not went that route nobody would buy their higher tier card with better cooling, the chips and the card itself are essentially the same on all models but the cooling solution they provide determines your maximum boost clock. You either have to replace your current cooling on the card or you have to trade it for a 3 fan cooler design. You can also under volt or under clock your maximum boost to a lower mhz in order for the temperature to drop. I had the same dilemma with my Galax 2080ti which was the more affordable one with a dual fan cooler, my temps reached 85C. I replaced the cooling on it with a kraken g12 and a single radiator aio and now my card boosts 2050mhz while staying at 70C. You really don't have to worry about your temperature, 80C range is still in perfect operating temperature. Consider replacing your cooling if your cooler is too loud for your liking, or if you want to overclock your gpu to a higher boost clock. Hope this is of help to you, keep well.
