Hot Graphics Card

With the big fan running check your gpu usage with afterburner and post.

You have to take into account it could be an errant reading,has it ever shutdown due to overheating? Have you tried different temperature monitoring programs?

You say nothing heats up? If you card was at 80C the air coming from it would be really hot,the back of the card would be too hot to touch so let the card temperature rise then touch the back of the card to check,if you can hold you finger there it isn't 80C.

I know you cleaned out the fan but have you removed the heatsink cover and cleaned the heatsinks?

If the card feels reasonably cold to the touch and the gpu usage is at zero I would try and run a benchmark to see if you can get it to artifact or shutdown,the safety shutdown temp is 125C but before that 110C the card will throttle to reduce temps its at about this temp you should see artifacts in the benchmark if its overheating or the benchmark will lock.

If your benchmark score is normal then it hasn't throttled and you haven't seen any artifacts there's something wrong with your temperature sensor.

Try speedfan also

There are only a few things that can cause heat,improper contact with the chip,dust in the heatsink,improper airflow due to slow or faulty fan,GPU usage due to driver issue,faulty card.

If you can eliminate all these one at a time and still have a high temp reading there's only one conclusion,the temperature is wrong.

Have you tried to clean the dust and reapply the thermal compound? It should help you to get better temperature. Also, for a more expensive option is to move it to an aftermarket cooler

That's pretty hot actually. Have you tried to use program like NVIDIA Inspector or CCC to have the fan run faster?
