Low score on I9-9900k Timespy
There seems to be a discrepancy between your performance and what you expect. At 1440p with a stable 4.7 GHz clock and a max of 75°C, a score around 6500 is quite low. Checking online results show many users achieving much higher scores. Since you're using an AIO and a 1080Ti GPU, it might help to ensure your cooling setup is adequate and consider optimizing your settings for better performance.
Is the OC performing well? It might drop slightly under load, like with the 3700X when stressed because the OC isn’t fully consistent. Consider running a small FFT on Prime95 to check.
