5800x3d and 9070xt for vr?

Hi guys, I currently have a 9070xt paired with a 5600x, and am considering upgrading to a 5800x3d, or wait until newer cpus become cheaper/ I have more money

I currently run VR (Quest 3) with the 5600x, and am struggling for 72Hz. I think i could be happy with locked 80, preferably 90.

I have seen Benchmark Odysseus' video, where the 5800x3d is right on the limit for 90Hz, although that being with the Pimax Crystal Super.

Anyone currently running 5800x3d or similar, how is your experience?

What would you recommend me doing?

Any other good resources i can check to optimize the settings?

Thank you for your replies!

I want to see different temperature drops for laminar vs turbulent flow.

The setup looks like this:

one component including one heat transfer in fluids, laminar flow, and turbulent flow

two nonisothermal couplings, one between the laminar and one between the turbulent

two time-dependent studies, one for each where heat flyx is applied from the start, and flow is applied after some time usig step function

Issue:

The turbulent case is unaffected by the flow entering, so the temperature keeps rising. in the laminar case the temperature drops noticably due to the flow.

i have tried:

splitting laminar and turbulent case into components

having two «heat transfer in fluids», one for each

running the laminar case, then applying rans to the laminar flow.

any help?

i have been 3d printing this part for initial testing and want to cnc machine it. I'm uncertain on the best way to create those luer locks. Are Luer taps common?

These are the options i have come up with:

1.

where these Luer connections are of the type M8 to Luer, like these

Any feedback? is option 1 or option 2 best?
