1080 TI FE (High Temperatures)

Basically, the video card worked on dropsy and the temperature was no higher than 65 degrees under load, in idle 30-35.
Now there is no dropsy, temperatures reached 85 in load and 55 degrees in idle time. Well, I did downvolting and lowered the load to 75 degrees and at idle 50-52 degrees. Well, if you leave the cooler with factory settings, then in idle time the temperature reaches 60 degrees. I set it up manually, so the cooler always rotates from 50 to 90 rpm. The question is, how fast will the cooler wear? also is it worth worrying about?
