Question about radiator placement in the Lian Li PC-O11 Dynamic

I'm building in an O11 Dynamic and I'd like to have one of these two configurations with two 360mm radiators:

Side mounted radiator intake (push), Top-mounted radiator intake (push)

Side mounted radiator intake (push), Top-mounted radiator exhaust (pull)

I've chosen these two mainly for aesthetic reasons so I don't have the fans visible inside the case. My question is if I'm limiting airflow and/or cooling by going with either of these and if one is generally a better option than the other.

I'm going to be cooling a 9900k and a 2080 Ti with this build as well.

Thanks for any input.

In my personal testing in in was best but only with exhaust fans in the bottom otherwise it just turned into a hotbox. Side in top out wasn't much worse but I was also using a very slow intake on the bottom. Sadly I didn't do any testing with nothing in the bottom.

As a heads up plumbing the side radiator if it is in the main chamber will be challenging as I believe the mounting holes force it to be in a ports up orientation. At least they do with the rad in the side chamber.

Thanks, that is interesting. I was hoping that the bottom and rear vents would be enough to exhaust the air with both side and top set up as intake. Also, were you running your top exhaust in push or pull? I would be running in pull and I'm worried if that would be inefficient.

I have a couple of HWLabs Nemesis 360 GTS that I'm putting in this build. Looks like the side rad can be mounted with ports at the bottom and most of the holes will line up. You're right though, not much room at all if it's mounted with the ports at the top. If it comes to that I'm hopping I'll be able to work some magic with fittings.

just a heads up, this case is tight if you plan on watercooling your gpu you pretty much need to have the vertical gpu adaptor and the front inside radiator really doesn't have a lot of space for some of the newer motherboards so be careful

(If y'all) ain’t ready for the old murder, then what you gonna do with the new me?

Thanks for the heads up. I still haven't chosen a motherboard but I'm thinking of going with an Aorus Master. Unfortunately, it has a gigantic shroud on the VRM heatsinks so that might be an issue. I'm planning on picking one up from Microcenter and hopefully it's returnable if it doesn't have enough clearance for fittings at the top radiator ports.

As far as the GPU goes, I bought a Heatkiller IV block since it seems to be compatible in either vertical or horizontal mount configurations. I do plan on mounting it vertically though.

biggest issues will be gpu and radiator. also that. its tight up there. I went with a dark so thats not a really bad issue for me but I can't do push/pull


honestly, build quality isn't very good either. I regret getting mine. I had a lot of issues getting gpu to screw in in standard configuration.

My top exhaust test would have been push. All tests were with bequiet! SW3 running between 900-1000rpm with a full load on the sig rig.

Only a clc on the cpu so not really comparable

I don't think the gts is thick enough to have any worry about either clearance. There is more than enough room up top and the side is staggered by at least 25mm iirc.
