I’m unsure about fully relying on userbenchmark, though it asserts its performance is significantly under what’s expected.
From what I see in the images and comments, Airflow seems to be problematic. It appears you haven't refreshed the thermal paste since 2017. The high temperatures likely stem from both issues, plus the addition of a 3070 chip, which generates more heat than most GPUs would have produced back then. A 7700K will still perform well under heavy load when temperatures rise. Opening the side panel usually helps lower the temps.
The temperature stays the same when you open the case. Adding more paste seems like a smart move, just in case it makes a difference
This should provide a modest improvement in performance, particularly with the reduced latency.
