I'm planning to build a custom loop in the Lian Li Dynamic O11, CPU and GPU blocks and I thought using dual 360mm and 45mm thickness radiators, one at the top and another in the back chamber area in the side of the motherboard tray, but when I searched the web I saw some people complaining that not all rads are supported in that chamber because it conflicts with the I/O front panel cables, like the USB, Power and Reset ones and it's mainly common to EK radiators, now I don't know what radiator to pick, I was planning the EK CoolStream PE 360 or Classic PE 360 (idk the difference between these two honestly) both 45mm thickness, but how do I know it will be compatible? I don't pretend to use radiator at the bottom of the case because my GPU will be vertically mounted.

Anyone can help me out? Thanks.

And this is the reddit thread I saw:

Seems that rad above 125mm width that are the problem to fit in the back chamber, not the thickness (it says in official Lian Li website that backchamber limit is 50mm, so 45mm would be fine I think?) or the length, so the Classic has 120mm width compared to the ''not classic'' that has 130mm, am I right in this?

Magicool G2 360 fits perfectly. It looks the same as EK Classic SE(except EK logo), but cheaper. Classic PE 360 also fits.

So the problem is only with the width that can't exceed 120mm? I can put a 45mm thickness without problem too?

If you go with 45mm for the side panel you might need to squeeze the front panel a bit more than this.

That is a 30mm thick rad.

Can you fit a standard 25mm thick fan behind that rad in the back section of the case?

@grayfox11 I need to measure how thick the SP120 are to answer you.. I remember I did fit two SP120 in the back of that rad, the lid closed but I needed to apply some pressure to make it go into place. IIRC I dropped the idea of having fans in there cause to make it work nicely I'd need slim fans. I'll come back later with the measurements.

EDIT: Ignore me, I'm dumb and misread this post. The info I posted below is regarding the O11D XL

According to the STEP files provided by Lian-Li there's ~57mm from the rear side of the motherboard panel where the rad would mount and the plates on the interior of the side panel where the dust filters attach to.

I was able to fit a HWLabs GTS360 (~30mm thick) and Noctua NF-F12 fans (~25mm thick) in that rear section. I will say the fan's anti vibration pads and possibly the pan head screws do push up against the dust filter a bit so you do have to finesse the side panel a bit when putting it on but once on you really can't tell.

Technically you'd be able to fit up to a 55mm thick radiator in that rear section if you mounted the fans on the motherboard side of the motherboard panel, BUT you're going to run into issues with the cable management panel in the rear. I've attached a screenshot showing how close the fitment is when you have the cable management panel in place, with the GTS360 it is almost touching the rad. For a thicker radiator you'd need to either modify the cable management panel or remove it.
