This is probably your only real solution for the time being.

Unfortunately given the games current development stage i don't think optimisation is a very high priority (usually done properly in BETA) and as such, as of right now, i don't think there is another solution.

I personally have a 2080 SUPER and my card never passes 40c but i have an AIO cooled card. In reality your card can run anything between 40-70c and not suffer any throttling or damage. So it's not *that* much of an issue, but i see why you came to find out if maybe you can get the temp down for sure.
