here we go again...

Soon after completing Schwarzgerät III, it became clear that I had made some errors. Most critically, the two cooling complexes on the bottom ought have been blowing into the machine rather than out, and the XFLOW240 radiator on the bottom of the PSU side ought have been inverted. In addition, the Phanteks T30 fan had just been released, and showed superior noise-performance characteristics relative to any existing Noctua product. Finally, I bit the bullet and upgraded to a 1000W PSU (from the 850W incarnation of the same EVGA Supernova T2 Titanium line).

Summary of changes

Custom loop
  • New hardware:
    • Added 12V RGB+fan hub to the top of the PSU side
    • Added Aquantia AQC107 10Gbps NIC.
    • Added aquacomputer NEXT sensor.
    • Added EKWB XTOP Dual D5 pumps and housing (measured at 35mL volume).
    • Added another 4-drive bay to the mobo side, replacing a Caselabs hard drive cage from the PSU side.
    • Added PCIe 1x card exposing an internal 19-pin USB3 header and 2 external USB3 Type-A ports.
    • Added Gelid CODI6 PWM+ARGB hub.
  • Cooling:
    • Added six Phanteks T30 fans and moved some others around.
    • Flipped bottom cooling complexes to blow inside the case (up) rather than outside (down), as there otherwise wasn't enough air flowing into the machine.
    • Inverted PSU-side XFLOW, and shortened associated coolant tubes.
    • Added drain port to bottom of PSU side, at the loop's true lowest point.
    • Added intake port high on mobo side.
    • Moved DiyHZ sensor above the video card.
    • Inserted NEXT where DiyHZ had been.
    • Added XTOP Dual D5 pumps behind where Monsoon had been.
  • Structure:
  • Power: Upgraded to a 1000W supply, eliminating the need for my jury-rigged 12V+5V Molexen.
  • Removed hardware:
    • Removed unused IcyDock 4x2.5" enclosure, freeing up 4x SATA data and 1x SATA power.
    • Removed second LSI SAS card, which was no longer needed.
    • Removed 4x140mm fans and associated brace from top.
    • Removed Monsoon reservoir+pump combo.
    • Moved Vario pump into Quantum Kinetic FLT, replacing dead PWM D5 pump.

New cooling configuration

Fan setup

Coolant temperatures are sampled at both reservoirs. The Monsoon sensor feeds into the Corsair, while the Quantum sensors feeds into the motherboard. Ambient temperatures are sampled via two sensors immediately outside the rear of the motherboard side, towards the bottom. One feeds into the Corsair, and one feeds into the motherboard. Currently, all PWM is then controlled based off absolute coolant temperature, but ideally it would be controlled using the difference between coolant and ambient temperatures.

Mobo side

Bottom

  • 2x Phantek T30 (push)
  • Hardware Labs XFLOW 240
  • 2x Noctua NF-A12x25 (pull)
  • aquacomputer NEXT sensor

The Noctuas provide 102.1m³/h and 2.34mm H₂O each. The Phanteks provide 114m³/h and 3.3mm H₂O each.

All fans are powered by a Corsair iCUE Commander Core XT capable of 4.5A. The Phanteks take 1.58W maximum for a total of 3.16W. The Noctuas take 1.68W maximum for a total of 3.36W. The four fans thus max out at 6.52W, 0.543A at 12V. In addition, the Corsair powers four LED strips at 1.835W each, for a total of 7.34W, 1.468A at 5V, and also the 1.56W (0.13A) NF-A14 on the front. The total 5V+12V draw is thus 2.141A.

The aquacomputer runs off USB, reporting through a proprietary protocol =\.

Top

  • 2 EK-Vardar EVO 120ER Black (push)
  • Hardware Labs HWL GTS360
  • Noctua NF-A12x25 (push)

The EK-Vardars require 4.46W each, for a total of 8.92W, 0.74A at 12V. The Noctua requires 1.68W, another 0.14A at 12V, for a total of 0.88A. The EK-Vardars provide 77m³/h and 3.16mm H₂O. The Noctua provides 102.1m³/h and 2.34mm H₂O.

These fans are all powered via a Silverstone fan splitter, itself powered via SATA.

Front

  • Noctua chromax NF-A14 (intake)
  • EKWB XTOP dual D5

The D5 pumps are powered off independent SATA hookups.

Back

  • EKWB Quantum Kinetic 240FLT D5 pump + reservoir
  • Phanteks T30 (intake)
  • DiyHZ sensor

The DiyHZ runs off the RGB hub, and is strictly visual: it does not report its measurements.

PSU side

Top

  • 2x Phanteks T30 (push)
  • Noctua NF-F12 iPPC-3000 (push)
  • Hardware Labs GTR360
  • 2x Noctua NF-F12 iPPC-2000 (pull)

These three fans are powered by the 12V RGB hub on the top. In addition, the RGB hub provides power for several feet of S5050 LEDs. I'm not sure about their exact power draw, but neither am I certain about the rating of this no-name passive hub, so I guess I just hope it doesn't catch fire.

Front

  • Noctua NF-A14 (intake)
  • 2xNoctua chromax NF-F12 (intake)
  • Phanteks T30 (intake)

These are all powered off a Gelid Codi6, itself powered off SATA.

Bottom

  • 2x Phantek T30 (push)
  • Hardware Labs XFLOW 240
  • 2x Noctua NF-P12 redux-1700 (pull)

All fans are powered by FAN5's two 1A headers, using two 1-to-2 splitters. The Phanteks take 1.58W maximum for a total of 3.16W. The Noctuas take 1.08W maximum for a total of 2.16W. The four fans thus max out at 10.8W, 0.9A at 12V. The Noctuas provide 120.2m³/h and 2.83mm H₂O each. The Phanteks provide 114m³/h and 3.3mm H₂O each.

Complete list of attachments

  • EKWB EK-AF ball valve
  • EKWB Quantum Torque T-valve
  • 2x EKWB Quantum Torque micro 90° MF
  • 4x EKWB Quantum Torque compression fittings
  • 4x EKWB Quantum Torque 6mm MM
  • 3x EKWB Quantum Torque 45° rotating MF
  • 4x EKWB Quantum Torque 90° rotating MF
  • EKWB Quantum Torque 28mm MF
  • EKWB EK-AF 50mm MF
  • 2x EKWB EK-AF 20mm MF
  • EKWB EK-AF 30mm MF
  • Bitspower 90° rotating MM
  • Bitspower 90° rotating MF
  • Bitspower 90° FF
  • Bitspower MM
  • 2x Bitspower drain ports
  • Bitspower rotating MM
  • 4x SDTC Tech 5mm MM

One of these cheap SDTC extenders ruthlessly stripped the threads from my Monsoon Series Two. I strongly recommend against their use.

Fans

All fans are 12V. The Phanteks T30s have an "Advanced" switch enabling 3000RPM, but I am not using it. All values listed are maxima; I am typically running them well below these settings. All radiators save the GTR360 are using push+pull. All fans are controlled via PWM.

Bespoke parts

I've got a number of self-designed 3d-printed (using my old Voxel, or my newer Qidi) parts in the machine. The OpenSCAD source for all such objects is available on GitHub.

Project Pompidou

My cabling situation on the PSU side is a mess. Inspired by the Centre Pompidou, I'm going to design and print skychannels in which to run the power cables. Ideally, none of them will be seen. To do this, I need:

  • Channel ends which bind to the various PSU plugs
  • Channels into which I can lay the cables, probably doubling them up. These channels will need run from the PSU to their targets.
  • Something at the hookup points
