judging by how my seahawk 1080ti is performing i say it could go as high as 80-84ish Celsius on normal fan profile.those temps are consider normal for these cards and if ur case have very good airflow or u manually control the fan i say u can reduce the temp more.here is one review of the card https://www.youtube.com/watch?v=jNJwhf0nyoo
