gtx 1080ti overheating

[Darren35]

setup - cool master 240
Ryzen 5 1600 OC 3.8Gz
Gigabyte GA-350 gaming -3
2x8gb , ram 3200mhz
ssd+hhd
Seasonic focuc plus 550W 80 plus gold modular ,

now when playing dirt rally 4 racing I have ultra , 3840x2160 multi sample 4 x msaa , anisotropic 2x gpu temp 77 -80 c gpu fan speed 90 , gpu clock 1759 , drops from 60fps.

I can get a stable frame rate if I reduce the setting but I feel this card should hold with these settings, the GPU is also quite hot and that’s only after 5 minutes of playing , the GPU has had new thermal paste with little result , Well this got me thinking about my psu 550w is it enough power? and could it cause my GPU to overheat? , my cpu temps are cool but this has water cooling so this probably wouldn’t get effected .

77-80 is not that hot. you've probably made it worse with new paste, new paste should only be needed after several years. What is the GPU utilisation? What does the clock speed do when you get the dips? If stable then it's not the card, it's the CPU feeding the card.

the clock speed reduces down from 1886 to 1759 so it down clocks slowly as temps rise , GPU is max performance

There is expected to be some variation. If the temp slowly reduces over time, and continues to reduce over 10+ mins as opposed to variations then it's a thermal issue.

There are several factors, the PSU could be one, would it cause thermal issues, probably not, but i'm not convinced you have thermal issues.
