I got linked to this on social media from someone, and I am cautiously optimistic about this. As you said, those bends will be near impossible to make as is. Manifolds are your friend, but fabricating manifolds in acrylic will be another thing entirely. Subbing for the ride!

I used to make gas tubing for semiconductor processing equipment (316L SS). You can make the bends, but it will take an extreme a lot of meticulous work. Given the detail in your renderings I would say you have the capability.<br><br>
A slight concern I would have is that you are using a lot of manifolds. This might cause some temperature differentials, especially with your GPUs. For gas panels we had flow meters and needle valves on the lines so we could control the split flows very precisely. I'm not even sure they make any kind of adjustable restrictor that you could use in your tubing.<br><br>
If you have access to CNC capability, you might want to make some restrictor plates (just a disk with one or more holes in it) that you could insert at the connection to each component that was in a manifold group. You would have to disassemble the loop to change the plates, but it would let you adjust the flow and keep component temperatures constant in a manifold section.<br><br>
Even if you get the water flow equal through each GPU, I doubt they will all produce the same amount of heat under load. I would be really impressive to keep you GPU temperatures within 1C or so of each other . . .<br><br>
Just some thoughts. The plan looks great and I applaud your ambition to build such a beast of a computer.

Once again thanks to everybody for all your interest in my little project. I should be posting another formal log entry in the next few days, with a few more details about the design requirements for Ironbeast.<br><br><div class="quote-container" data-huddler-embed="/t/1544054/build-log-ironbeast-a-fully-watercooled-x-99-quad-gpu-900d-build/40#post_23647474" data-huddler-embed-placeholder="false"><span>Quote:</span>

Fabricating a manifold completely from scratch isn’t that easy in any material, so I plan to use an advanced problem solving technique known as ‘cheating’. I have (hopefully) found a way to construct a passable approximation of a proper bespoke-made manifold, with the 45 degree flow-splits and at the right size and spacing, through some creative use of existing components.<br><br><div class="quote-container" data-huddler-embed="/t/1544054/build-log-ironbeast-a-fully-watercooled-x-99-quad-gpu-900d-build/40#post_23647913" data-huddler-embed-placeholder="false"><span>Quote:</span>

You’re quite correct about the manifolds, however the differences in coolant flow rate between the GPU blocks should (in theory) be relatively minor at this scale and pressure. Provided the overall flow through each block remains high enough, any variance that does occur should have a negligible impact on the cooling effect becuase the specific heat capacity of water is so high. Differences in the heat output between the different cards is a worry, but shouldn’t be a major problem so long as the flow rate is sufficient and one card is not working massively more than the others.

Not sure if this was already written but, I am not sure that a single AX1500i be enough for that rig. I would suggest go with 2xAX1500i or Seasonic...

I'm not sure how SLI distributes the work load between cards. That was exactly my concern that one of your cards might end up with more work and need a little extra cooling. I wanted to offer a possible solution just in case it was a problem. With enough water flow it shouldn't be though . . .

What makes you think the AX1500i isn’t powerful enough? My assessment deemed 1500W to be more than sufficient. Am I missing something?<br><br><div class="quote-container" data-huddler-embed="/t/1544054/build-log-ironbeast-a-fully-watercooled-x-99-quad-gpu-900d-build/50#post_23654205" data-huddler-embed-placeholder="false"><span>Quote:</span>

Thanks for the input, I really appreciate it. As you said managing coolant flow through manifolds is complex business, so simply maximising the flow rate through all branches seemed to be the better option. That said your restrictor plate idea may prove very useful in the other part of the cooling loop, if my configuration tests find benefit in running the CPU and motherboard cooling in parallel rather than series.

If anything there is the EVGA 1600 G2/P2/T2, all cheaper than AX1500i<br><br>

The G2 version is 309.<br>
The T2 version is 409.

Only problem is that I have the AX1500i already. So if I’ve messed up and it isn’t powerful enough for the full rig, I will be…very displeased.

Oh I see, well I don't think there will be an issue with 1500w

<div class="bbcode_center" style="text-align:center;"><i>Hello everybody. Another formal build log entry for you today, ‘Design Overview’. It’s another longwinded one I’m afraid, basically an outline specification for the build. It’s probably not that entertaining (my apologies) but my education has conditioned me to include something like this. I hope to rattle through the next couple of entries quite quickly (a more detailed ‘what and why’ rundown of the component choices and a rough progression plan for the build) so we can move on and start looking at the interesting bits.<br><br>
Once again, thanks to you all for reading and for your comments. It really does make my day.</i></div>
<br><div class="bbcode_center" style="text-align:center;"><span style="font-size:16px;"><b><span style="text-decoration:underline;">Design Overview</span></b></span><br><br><i>The basics of what I want this build to be and do.</i></div>
<br>
The essential purpose of this project is this: to build the best machine that I can, because I can. That said there are some particular design aspects I want to focus on, as well as specific requirements for a computer which I do actually need to <i>use</i> rather than just look at. Although the small matters of complexity, practicality and cost can never be <i>entirely</i> ignored, in this project they are very much taking a back seat to performance and aesthetics.<br><br><div class="bbcode_center" style="text-align:center;"><b>Performance:</b></div>
<br>
I do tend to subscribe to the idea that there is no such thing as overkill; that no excuse is required in pursuing power for power’s sake. However high-performance characteristics are a necessary requirement in this case, because this machine is going to have quite a lot demanded of it. The Ironbeast will be expected to handle all of the following (in order of increasing system workload):<br><br><div class="bbcode_indent" style="margin-left:4em;">• <i>Basic Computing</i> (obviously) – internet browsing, email, word processing & spreadsheets, plus storage capacity sufficient for my music, photos and software.<br>
• <i>Digital Illustration and Graphic Design</i> – lightweight work, mostly simple drawings. Diagrams, text, vector graphics and a little artwork using various different software packages.<br>
• <i>Gaming</i> – a general mix of new releases and older titles. It should easily run new games at maximum graphics settings and continue to do so with future releases for at least 4-5 years.<br>
• <i>Computer Aided Design and 3D Rendering</i> – just the basics; 2D technical drawings, 3D part and assembly design, ray traced image rendering. The latter in particular is immensely power hungry.</div>
<br>
The Ironbeast should have sufficient processor power and RAM memory in order to allow it to perform these tasks without significant effort. Since the latter two functions also necessitate heavy graphics power, support for a multi-GPU setup will be necessary. The graphics cards will need to satisfy both the ability to process a large amount of visual data in a continuous stream, as required by games, and in massive intermittent blocks as required by CAD. Therefore cards possessing both high speed and high memory capacity will be needed.<br><br>
In addition the system should also:<br><br><div class="bbcode_indent" style="margin-left:4em;">• Provide support for a future upgrade to a 4K resolution monitor.<br>
• Facilitate the operation of multiple monitors/TV screens.<br>
• Support a significant overclock of CPU, RAM and GPU(s).<br>
• Be able to operate in a stable state at medium to high output for a total of anything up to 12 hours a day, most days.<br>
• Be able to operate in a stable state at high output for unbroken stretches of 4 to 6 hours.<br>
• Provide adiquate functionality in the tasks listed for at least 5 years without upgrades to primary components.<br>
• Include capacity for the fitting of extra storage through additional SSDs.</div>
<br><div class="bbcode_center" style="text-align:center;"><b>Aesthetics:</b></div>
<br>
As far as I am concerned if you’re going to make something, make something beautiful. Functional but ugly annoys me every bit as much as elegant and useless; either is a failure. As such making this build look good is just as an inherent a part of the process as making it work. A lot of computers are designed with variations on a visually striking, high-contrast, UV-glow look. I think these are very cool, in a slightly attention-seeking bright yellow Lamborghini kind of way, but they’re not really my style. Instead I’m going to try and go for the following aesthetic, which is hopefully a little bit more subtle yet still eye-catching.<br><div class="bbcode_indent" style="margin-left:4em;"><br>
• <i>Black base colour</i>; with matt (metal) and gloss (acrylic) finishes on different surfaces.<br>
• <i>Silver contrast colour</i>; used on fittings, edging etc. Polished or semi-polished finish.<br>
• <i>Gold accent colour</i>; picks out certain features, e.g. compression fittings, to add visual interest.<br>
• <i>Transparent sections</i>; generally used to facilitate lighting effects. Clear and smoked finishes.</div>
<br>
The main reason for this rather colourless livery is the plan for a fully programmable lighting rig. The colour scheme is designed to work well with whatever lighting tones I choose to use, and when the system is unpowered. Whatever colour there is in the build is to be provided entirely by the LEDs. This should let me change the overall look of the build whenever I want to, and to suit whatever mood I happen to be in, simply by reprogramming the case lighting.<br><br>
The other aesthetic concern is that the rig should have a very ‘clean’ look to it - not just neatly done but laid out in a way that is visually pleasing in itself, whilst still remaining practical to use.<br><br><div class="bbcode_indent" style="margin-left:4em;">• No cables should be visible from the nearside and set out as neatly as possible on the offside.<br>
• To protect from fine dust passing through the filters, circuit boards should not be left exposed. However they must remain accessible and all necessary ports kept clear for cables.<br>
• As far as possible, components should be located to produce an aesthetically pleasing layout.</div>
<br><div class="bbcode_center" style="text-align:center;"><b>Cooling:</b></div>
<br>
The requirements for the cooling system encompass both the practical and aesthetic concerns detailed above. The system should fulfil the following requirements:<br><br><div class="bbcode_indent" style="margin-left:4em;">• Deliver excess cooling power above the minimum which the rig requires for stable operation, thus maintaining lower component temperatures to prolong its lifespan.<br>
• Facilitate adequate coolant flow rates whilst not compromising (and preferably enhancing) the rig’s aesthetic appeal.<br>
• Maximise efficiency across different system states by allowing all components shared access to the total available cooling capacity.<br>
• Minimise pump and fan noise to more acceptable levels than my previous computers.<br>
• Automatically adapt fan and/or pump speeds via software to suit different system loads.</div>
<br><i>These requirements have developed a lot as the design has evolved, getting more extensive each time I think of new things I want to do. Implementing them, especially points two and three directly above, are the reason why this build has become so elaborate.</i>

Thanks to all of you, you're much too kind. I'm glad people like the design and are enjoying the build log so far; it’s a great encouragement for a very self-critical guy like me.<br><br>
I hope to have some more stuff posted for you sometime in the next few days.
