I would set both rads to intaking cool ambient air.

By having both rads intaking the coolant temp is as low as it can be, so the air going into the case is cooler. With one intake one exhaust the coolant temps are higher so the air going into the case is warmer and the overall air flow rate is lower too.

In testing most cases will work better with both rads intaking but I haven't seen the o11 specifically tested.

Its commonly suggested that rads intaking will cook the internal components but when you have two rads worth of airflow going through the chamber it provides more air to cool and its lower temp air too so heat can't really build up.

Hey bud I have gtx dual rads360 420 not ek.. but I had that problem switching last case. I do now have a cheap power supply so after I installed everything before mounting cpu block on cpu with its tubes hooked up. and no power to motherboard in case it leaks.. I will run pump and tilt pc all the way back hear bubbles then forward sideways also I will lift up cpu block hold upside down for few seconds bam system is bleed used to take me longer.
Also not sure but on my rads I read if you all looking at both inlets have intake flow to rad the right one and fluid come out left one maybe that is just because the way duals are made …
And last tip I delided my 9900k so I know what direction chip is running I made sure when mounting (cpu block I looked at micro fin orientation and made sure running length of chip.. good luck

Check the cfm rating on the RGB fans. If I remember correctly, they have 1/2 the airflow as a non-RGB ML Pro. It's the reason I did not buy RGB fans.
