Video Card Tubing
I going to power both of the video card LED strips off of one header on the motherboard. I didn’t want to splice the two cables together as this would be difficult to deal with both during the installation of the video cards, and whenever they are removed in the future.
I saw this little “Y” adaptor on PPCs so I ordered two of them.
I hooked up both LED strips to this “Y” adaptor and powered up the tester I use for testing LED strips and fans while outside the case, and only one LED strip lights up! It turns out that two of the wires are not making contact at the connector terminal end that plugs into the motherboard.
So I plugged the LED strips into the second “Y” adaptor, and find out that it has the same problem! The motherboard end is using dupont pins like the USB five pin cables use, so I cut the terminals off and crimped all new ones on. Now both LED strips work fine
I put a sleeve over the whole thing, and both LED strips plug in and work fine now. This will plug into the header below the 24 pin cable. I formed it with a 90° bend so the LED cables will go straight down behind the 24 pin cable bend, and plug into the adaptor.
Here you can see the video cards only have the waterblocks installed with no backplates. While I was waiting for the spacers I needed to install the backplates I worked on the tubing.
It took me four attempts to bend the tube going from the CPU block to the lower video card! The first one I didn’t quite heat the tube enough for the second bend, and it kinked a little bit. The second attempt I cut the section going into the CPU block a little too short. The third attempt I managed to basically do the same thing I did the second time
The fourth attempt I am happy with. The tube comes straight out, and the double bend is similar to all the bends on the long tubes going into the top and bottom radiators.
Also notice while I’m fitting all these tubes that I leave the secondary o-rings, and the collars off of all of the fittings until everything fits the way I want it to. The collars just get in the way, and can even scratch the tubing if you aren’t careful.
I was planning to make a bent piece of tubing going from the top video card to the 900P waterblock, but there is just not enough room on top to get a 90° bend and a fitting. I have a pretty good selection of various fittings on hand, and I must have tried a dozen different variations of fittings to make this work.
Finally this was the only combination that would even work at all. A single rotary 90 into the 900P waterblock along with a dual rotary pointed down to the video card waterblock. This actually lined up nicely with the port on the video card block, and when I put my level on the two fittings it is perfectly level
Also here you can see how the LED harness I recently re-did for the 900P now loops over the top, and down rather than going across the top of the waterblock.
After all four pieces of tubing are fit, cut, and bent to my satisfaction I pulled the video cards and tubing back out. I installed the video card backplates as previously shown once I had the required spacers.
Now I put all the secondary o-rings, and the collars back on the fittings. Here I use masking tape to hold the collars out of the way, and to prevent them from scratching the tubing. This also gives me some wiggle room while I installed these two video cards with the two connecting tubes all together at once.

All four tubes installed with all the collars locked down tight.
