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
Try with 3 PCIE cables to see if that solves the problem.
If you must go with only two then switch the plugs around so the daisy chain ones plus into different slots. I don’t think power draw is spread equally on all three. Assuming your PSU is high quality and should be able to handle the load.
