The EK-Quantum Reflection² PC-O11D EVO XL distro plate features numerous ports and offers multiple ways of properly connecting it to other loop components like radiators, CPU, and GPU blocks. This article explains exactly which fittings (like extenders, adapters, angled adapters, etc.) can and should be used to properly connect the radiators and water blocks to this distro plate.

Choosing the fittings according to the radiator(s) used in the loop
The Lian Li O11 Dynamic EVO XL case provides enough room to fit several different-sized radiators simultaneously, so we decided to explain which fittings are to be used with different radiator setups. Radiators must be Matrix7 Compatible in order to fit the lists below.
Bottom radiators and port connections

| X420 Push-In | 1 | EK-Quantum Torque Extender Static MF 28 |
| 2 | EK-Quantum Torque Rotary 90° | |
| 2 | EK-Quantum Torque Push-In Adapter M 7 |
Additional info:
- X420 Push-In: Using an X420 in the Top position is only possible when the motherboard tray is moved to the lowest position! THIS WILL MISALIGN ALL CPU AND GPU PORTS! 2 EXTRA SLOTS OF CLEARANCE MUST BE GIVEN TO THE BOTTOM RADIATOR WHEN THE MOTHERBOARD TRAY IS MOVED!
Since X420 does not outperform the P420 until 3000RPM+ there is no sensible reason to do this however the distribution plate does allow it.

GPU and CPU water blocks connectivity
Given the wide variety of motherboards and graphics cards available on the market, this distro plate has multiple ports for CPU and GPU connections, so you must choose the most suitable fittings, extenders, and adapters for your project. We also offer Offset Fittings to help you achieve straight-line tubing routes from your CPU/GPU block to the DP ports.
Note: All Reflection², Vector², and Velocity² products, as well as all the Quantum Torque fittings, adapters, extenders, and Surface radiators, are made according to the EK-Matrix7 standard, enabling more user-friendly port connectivity. It also allows us to provide you with detailed info on how to easily connect the CPU and GPU blocks (Velocity² and Vector²) with the DP ports.

Why were the fans mounted behind the side radiator and not in front? Is there a compatibility issue? I have seen other builds with this distro work perfectly fine with extender fittings and the fans in the front position. I'm planning my build and am confused on why EK chose this as the default config. Any answers/clarification would greatly help!
Hi Riad,
Thank you for the questions.
The radiator hits the case and there is a small lip at the bottom where the radiator goes "through" the mid panel of the case. A few customers have just cut that off. It is a very easy mod but could not support it that way from the factory.
Thank you for your answer Grega. Do you happen to know what length of extender fittings I would need to make this work?
To clarify, I will have the bracket in the recessed position with the a P420M radiator and would like to know what length of extender fittings I would need to make up for the gap from flipping the bracket and mounting the fans on the front side? Your help is greatly appreciated.
I considering a first custom loop, and I have some questions when looking at this page and the manual for the Distro plate.
When using this Distro plate in an inverted configuration, looking at the diagrams in the manual:
https://www.ekwb.com/shop/EK-IM/EK-IM-3831109908532.pdf
Is the only build-in drain port is external to the case?
The fill port on the plate seems to be low, just looking at the diagrams, does the plate lose water volume when inverted?
This page has a GPU diagram for determining the offsets you need with a GPU Block, but how do I determine the offsets for a CPU block?
Hi James,
thank you for your questions.
Yes, if you use the Distro Plate in a flipped configuration, the only drain port is located on the external side of the DP. You can use the inner or external fill port when the DP is used in a flipped configuration. If an inner fill port is used when flipped DP, yes, the coolant level can be a bit lower.
There are a lot of different MBs on the market and it is close to impossible to list all of them and put the correct off-set fittings on that list so we sadly cannot recommend the specific off-set for a specific MB, but we can say that most of the boards (water blocks on them) can be connected with the 0-3 off-set so if you purchase 2, you will mostlightly be covered. If you want to be even more sure, you can purchase 2 of the 7mm ones and return them if you do not need them.
I hope this helps and if you have any more questions feel free to ask.
