AMD 5900x, Nvidia 3090 FE, Meshilicious Ssupd Custom Water Loop Build

Originally I had hoped to use EK ZMT black tubing + quick disconnects as I had done in my previous build (a top rad Cooler Master nr200p with the the founders card still air cooled) but simply did not have the space.

A shout out to Reddit user u/jamespx4 who's build really inspired me to jump in and I stole some ideas from him.

I spent a lot of time on fitting and ordering new pieces to make it all work. Once I realized I could not use the ZMT and that those thicc fittings would be an issue, I decided to use 12mm tubing. I have seen complaints about their bend as it flattens somewhat but I do not find it offensive.

I had used spacers on the riser cable mount and the vertical GPU holder to try to make the Res ang GPU block on the same plane but in the end I used only 3 washes to space the Res and somehow everything else just lined up with their stock spacing. I spent probably 4 nights messing around with the GPU, Rest, and CPU to get them to where I wanted, and another few nights with the radiator extensions.

The Mobo spacers are crucial to this build. Without it none of this fits.

Cooling Setup

In my Bios, I set to ignore the CPU Fan so that I could boot with the fans connected to the Chasis Fan header. This setup allows me to use the on board T_SENSOR to control the Chasis Fan speed based on coolant temperature.

I have not spent a ton of time tweaking this yeat but the fans go from roughly 20% at 20c (never going to happen) to 60% at 40c (pretty normal, think I'm usually seeing 37-39 deg c water temp), and 100% at 60c.

Mods

  • Custom mounted the Res. Made a template with paper using the holes on the back of the block. Drilled with a hand drill and cleaned up the openings with metal files. Spaced with 3 washers on each screw. It only has 2 screws in. It causes a slight downward pitch that I was going to counter with an aluminum strip behind it but decided it was fine.

  • ~30mm in standoffs/spacers used to move the mobo out but keeping the rest of the case the same. Creates a cavity for cabling.

Bummers

  • No USB C header on this mobo. I don't want the limited USB ports of the B550I.

  • Using 1 RGB splitter means the CPU, GPU, Res, and Flow Indicator act as 1 component in Aura (this software sucks but whatever, not having to run even more software is nice

  • The spacers I had to use for the Mobo meant I could not use the I/O shield. I really wish it would fit but its a few MM off now.

  • I can't find a few screws from the build like the white piece that goes next to the Mobo when in "4 slot mode"

Wins

  • Squeezed the bend from CPU to Res over the top gap! I am so happy about this one. There is still room to access the fan and RGB headers.

  • Using coolant temp for fan curve with no additional hardware or power cables.

  • Using the standoff suggestion gives you room to hide a lot in the center cavity!

Still to do:

  • custom PSU cables. I have everything but the connectors... company I ordered from has ghosted me so I have to figure out what to do to cancel and order they won't address (assuming reach out to PayPal?) There is a LOT of room to save once I can remove these terrible Cooler Master PSU cables. It will be especially awesome to have a custom 12pin for the GPU as right now there are two cables with dog ears + the adapter... its a lot.

  • procure a second glass panel. Ssupd said they hoped to have them in stock at Newegg in a couple weeks, a couple weeks ago.

  • benchmark/undervolt/overclock

  • possibly switch to EK Mystic Fog -- I'm telling myself not to waste the time

  • figure out how to drain this thing - ha (think ill attach a hose to the drain port in res and flip the case over.)

Conclusion

This was stupidly expensive, exasperating at times, and completely satisfactory. I am so happy with this build. The case allows for awesome components and build variations. After having started with water cooling in a Lian Li O11D and to see how far all the blocks and resevoirs have come in the last few years is really cool.

I'm looking forward to more options from other vendors (I had considered going full Alphacool but the EK blocks are still my favorite ATM). Lets just hope supply catches up!

I hope the pictures and information help anyone else looking to do a similar build! Let me know if I did anything especially stupid.
