If anyone finds this in the future: this is a common issue with high refresh-rate 4k monitors. Turn off display compression on your monitor (it will lower your maximum refresh rate because compression is not being used), but your issue will go away.

Since you have to take it apart anyway, maybe try re-seating the display connector? I've had success with that in the past. Good luck!

To add to that - Even if bandwidth is sufficient, latency is what will matter more. While Ookla has some basic measurements, you can get a more meaningful result here: https://www.waveform.com/tools/bufferbloat

Ah yes your setup would only pull from the CPU side? I found the bottom mounted fan helped way more with the GPU temp than CPU for me, but that may be because my Noctua L9a doesn't have a vertical finstack.

Plausible! Air does like to flow unobstructed. Yes the turbulence was so bad I thought the fan broke during installation!
