My 2020 rebuild, [[Schwarzgerät_II|Schwarzgerät II]], was a beast of a machine. Like the Hubble or LHC, however, I had to give it more powah. The 2022 upgrade, Schwarzgerät III, does just that despite scrotumtightening supply chain madness. This rebuild focused on cooling, power, and aesthetics. I require that the machine be no louder than ambient noise (I live in the middle of [[Atlanta|Midtown Atlanta]]) when weakly loaded—I ought not hear the machine unless seriously engaged in active computation. At the same time, I want to overclock my 3970X as far as she can (reasonably) go.

Most calculations will require knowing the total amount of coolant in our system. Fluid volumes of liquid cooling components are irritatingly difficult to establish (once the hardware is installed, anyway). With an inner diameter of 12.5mm, the ZMT has a cross-section of 122.72mm² (0.~~015m²~~). I got the EKWB fluid volumes directly from their support channel. G¼ has a diameter of 13.157mm, but that doesn't tell you anything about the inner diameter, which is not standardized =\.

As I detailed regarding [[Schwarzgerat II]], the 3990X is an amazing achievement in chip design and fabrication, but I believe it to be severely starved for many tasks by its memory bandwidth; with its four memory channels populated, the ThreadRipper 3990X can hit about 90GB/s from fast DDR4; its ~~Epyc~~ brother can pull down ~190 through its eight channels. For my tasks, it's rare enough that I can drive all my 32 cores; with the 3990X, I'd be paying twice as much to hit full utilization less often, and be unable to bring full bandwidth to bear when I did.

I absolutely 🖤 my 3970X, though. Bitch screams. Anyone overclocking on Linux should be aware of [https://www.linux.org/docs/man8/turbostat.html turbostat]. The 3970X supports 88 lanes of PCIe 4.0, of which the TRX40 chipset consumes 24, leaving 64 for expansion devices. I've got 16 (GPU) + 16 (Hyper X) + 2x8 (LSI cards) + 12 (M.2 onboards) for 60 total, coming in just under saturation.

[[File:Tobsun.jpg|200px|thumb|A 12V->5V buck transformer, more efficient than a mere voltage regulator.]]

I began to run into some serious power issues on this build, originating in the Exos X18 drives (of which, you might remember, there are 14). It will be worth your time to consult the [https://www.seagate.com/www-content/product-content/enterprise-hdd-fam/exos-x18/_shared/en-us/docs/100865854a.pdf Exos 18 manual]. Remember, 12V is for the motor, and 5V is for the logic.

Line 457:

Line 447:

|-

|}

The Silverstone supports draws up to 4.5A (54W). The Corsair supports a 12V fan draw of 4.5A (54W) and a 5V RGB draw of 4.5A (22.5W).

The PSU claims support of up to 100W as 5V (20A), and up to 850W as 12V (71A). The 5V line is dominated by hard drives, which will consume 65W when in active use (and 70W when spinning up). Beyond them, there are very few 5V draws; the ARGB light strips are going through the motherboard's ARGB headers, the internal USB hub and downstream devices are getting 5V from Molex, and the Corsair is pulling over SATA. Even if the motherboard ARGB headers are fed by the ATX12V's 5V lines, we're talking 20W max, and probably less than that.

==Ongoing issues==

* My flow rate is lower than I would like, assuming this flowmeter to be reliable. Maxing out the PWM pump hits desirable flow rates, but with more noise than I want. I think there might be some flow reduction in the tubing between the flowmeter and Quantum Kinetic; I'm considering replacing that with hardline. For all I know, there's still a big air pocket in some radiator.

Beyond them, there are very few 5V draws; the ARGB light strips are going through the motherboard's ARGB headers, the internal USB hub and downstream devices are getting 5V from Molex, and the Corsair is pulling over SATA. Even if the motherboard ARGB headers are fed by the ATX12V's 5V lines, we're talking 20W max, and probably less than that.

 ==Ongoing issues==
-* My flow rate is lower than I would like, assuming this flowmeter to be reliable. Maxing out the PWM pump hits desirable flow rates, but with more noise than I want. I think there might be some flow reduction in the tubing between the flowmeter and Quantum Kinetic; I'm considering replacing that with hardline. For all I know, there's still a big air pocket in some radiator.

-* I'm not sure this 4x140mm structure of fans in the roof is really doing me any good, and need to test with and without them. What really happened here is I saw [[Noctua]] had a chromax.black 140mm and creamed my jeans and was like "gotta order that!" Then I realized I had no 140mm mounts, and rather than do something sensible, I built up an autistic rage and was like OH FUCK YOU GOD, YOU TRY TO FUCK ME, NAH, I'LL JUST BUY THREE MORE FANS AND THREE-DEE PRINT MYSELF A BARUD-DÛR AND IT'LL INTERLOCK BECAUSE I TOO AM A MASTER OF REALITY, YOU OLD SHITTER, THEN I'LL GO BACK IN TIME AND KILL MY PARENTS BEFORE I CAN BE BORN AND UNDO ALL YOUR WORKS BITCH and then it was like, well, better use these fans I guess.
