i purchased a used evga ultra ftw3 3080 (no overcloked) from my close friend . i run modern games on 4k ultra setting fps is above 60 but temp is near 85c ! when i run 2k ultra temp is 81c. i tested unigine heaven in extreme setting every thing is fine temp is 82 max ,fps 82.6 score 2082 !

Last night, I tested furmark, after a minute the software crashes when the temp reaches 74, is there really a problem with the card?

my psu is coolermaster 750w psu 2 direct PCIe power plus 1 daisy chained is plugged into the GPU

in msi afterburn max tpd is 380w

What other tests can I do so that I can feel at ease because I have no problems in the game except the temp?

my full specs:

i5 12400f

ram 2*8 gb ddr4

6x 120m fan case

coolermaster td500 crystal

85C, unless your airflow is shit, means that it's time for new thermal paste on the core.

Use HWInfo64 to monitor the card while you're running furmark. See what the hotspot temperature gets up to. I bet it's over 100C. 105C is where it will VRM throttle and ramp the fans to emergency mode, which runs them beyond the 100% that the user can set to try to keep the card from dying.

If the hotspot is more than 15C above the core, that's another indication that the core needs a repaste, since there are spots with no paste coverage due to pump out and dry out over the time it was used by the original owner.
