I've a 2060 Super Amp Extreme (not the same GPU but for you to get the idea) and it heats up quite a bit as well. Under auto fan curve, it hits ~76°C and even with fans on full blast, it reaches 70°+ anyway. (I've cooler master MB511 with 3 intake and 3 exhaust, with moderate fan curve.)
You can either use aftermarket VGA cooler or G12 bracket + and AIO or deshroud it and put some good 92mm fans on the heatsink.
