My Gigabyte 1660s Oc 2 fans idles at 53 degrees room temp at 26 and when gaming it reaches over 83 degrees (at 100percent fan speed) ive repasted the thermal paste and adjusted the fan curve. I'm not sure what to do

I tried everything im not sure what I'm doing wrong. I repasted the GPU many many times trying to figure out whats wrong, I undervolted my GPU and power limited it.
should I bring it to a shop?, should I sell it? , just use it until it dies? or slap a water block on it?
