This is what I would consider the halfway point. Pat yourself on the back you’ve made it this far. Be wary though the next few parts are what will make or break your loop, time to install the tubing! You will need a couple of tools for this. The first is either a tubing cutting tool, or a good sharp pair of scissors. Although the tube cutting tool does a much cleaner easier job, I used scissors for years (because I’m cheap) without issue. You will also want a pair of pliers, preferably needle nose.
The first thing to do with tubing is to attach the entire roll to your starting barb. I chose the outlet of the pump as this is likely to become tight for space later and I wanted to get it out of the way. Simply slide the tubing onto the barb (may take some force).
Now route the tubing to the next barb you want the water to flow to. I chose the radiator as this would make a quick, short and clean looking loop. Hold the tubing up to the barb to estimate how long you want the run to be. Always make to sure to make it slightly longer than it looks. You can always shorten, but never add more length to the tube. Nothing looks worse than a piece of tube that was cut too short and stretched too tight to make up for it. Since this is one of the pieces attached to the X20 I also want this to be longer so I can slide the X20 out to fill it.
Before attaching the tube to the barb you need to slide two clamps on the open end. Now attach the tubing. Slide one of the clamps to the first barb and clip the ends together. Using the pliers carefully tighten the clip as tight as you can. This is important as leaving it too loose can allow water to leak between the tube and the barb. Simply repeat these steps three more times and you should have something like the photo below.
Now it’s time to wire and then fill the loop. If you’re 24 pin is connected to the motherboard you will want to unplug it and attach the included 24 pin jumper tool. Also unplug your 8 or four pin from the motherboard and any other accessories (GPU, etc.) that will receive power from the PSU when on.
Attach the power for the pump to an open molex adapter if you’ve not already done that. Since I don’t have enough room to fill the reservoir with the X20 in place, I slide it out to fill.
I also recommend installing the single larger included LED in the LED port on the back of the X20. This will let you know that you do have power when turning on the PSU if nothing happens with the pump. Attach the LED to another open molex adapter.
Using distilled water only or water cooling coolant, you can now fill the reservoir. This is done in stages. First you just want to fill the reservoir full. You can tell that it’s full by either looking in the fill window, or through the fill port. Once full turn on your PSU. This will power only the items attached, and only turns on because you have tricked it to think the motherboard is calling for power.
Since the loop is empty it will quickly drain the reservoir, pumping water into the rest of the loop. When you see the water getting low quickly turn off the PSU, and add more. Before you do anything else check each fitting for leaking water. You can use a piece of paper towel to check. If you do have a leak, tighten the barb into the port, or tighten the clamp onto the barb more. Turn the PSU back on only if you have no leaks, repeating until the water stays at the same level in the reservoir. There will likely be air in the loop that will take time to bleed out and is normal. You will want to put the fill plug back and slide the X20 into the 5.25” bays.
Let the loop run this way for several hours, preferably at least overnight. In the state that it’s in, you can not damage your components with water. Distilled water is non conductive and so long as you completely dry anything that gets wet before powering it, you can not cause any damage.
Once you are sure you have no leaks turn off the PSU. Now you can plug everything back in like normal. You can install the LEDs into the block now as well. This is another molex plug to be plugged into the PSU.
With the LEDs installed the installation is complete. It is safe to power the PC on and those LEDs; they certainly add a nice blue glow to the interior of your build!
One final note with installation:
Since you are not necessarily plugging the fans, and certainly not the pump into the CPU_FAN header, your motherboard is not going to be happy and will give you a CPU fan speed warning. Some motherboards will support disabling the CPU fan warning, otherwise you will want to plug a fan into this header. If you don’t do one of those things bios will not allow the board to boot.
