I believe it has to include a fan. The only big ventilation opening I can see is right above the CPU. The name of the case is RVZ02In this size you won't get much better than nocuta. My question is Does it have to include the fan?
Thing like this:

Might get away with amount of air your gpu will push though the thing.
You might get away with placing the fan a bit further / sideways to the cooler, just do it vertically to the fins, or horizontally in a way that air won't go perpendicular to the fins....
list of all we can takeLove those ITX builds.
I think your best cooler will be the big shuriken2 rev b.

I am using one is a build with a overclocked 6600K in a lian li PC Q08 case.
The design of the RVZ02 gives you a more direct source for air intake.
That is a good thing.
You may be able to OC a bit with a Z390 based motherboard.
