Rtx 2080 ti idle temp Mine idles at 29c on air but i changed out the thermal paste. This card has the passive fans system and the fans stay off all the time unless the card is under load, so that's the idle temp with no fans. I just wanted to know what is the ideal temp so I would not damage my graphics card. Other forums specifically talking about 2080ti cards said that anything under 90°C is fine, BUT these forums tended to be talking about video gaming so I was worried they might be referring to a limited time at that temp (while playing) vs mining which would be 24/7 (while not gaming in my case). Hello, I recently finished building my 82C is still fine for the card. Thread starter aeidolone; Start date May 18, 2019; A. Then when using it with full utilization, it will jump way above 80c, passing 85c. Cheers . For some reason, the idle temps are in the mid 30's, but under load, it hits 85C without any overclock on the card at all. I tried quiet mode and the results are the same i get 79C instead of the 75C they say in the reviews even with an open case. qksnjkqiwszgddvfmddpgjvdylwsxtdssgfqernspftzyticcslvkyeqgjfddxzkbromnxbtv
