Aaand, we almost immediately had a leak.
A surprisingly slow one too, considering at some point the o-ring on this Aquacomputers temperature sensor fell completely out, and I never noticed...

Digging through the water cooling box for spare o-rings that look like they will fit well...
Hmm.
I'm wondering if I got a bad pump.
The pump I was already using in my old build was nice and quiet. You can barely hear it.
The new pump, holy shit, the pitched hum is enough to wake the dead...
See below, I first plug in my old one, then plug in the new one, and then disconnect the old one.
Any thoughts? I'm wondering if I should request an RMA.
They are both EK D5 PWM G2 pumps.
My old nice and quiet one was manufactured in 2018, the new loud one was manufactured in 2019.
edit:
Apparently hearing th edifference depends very much on what speakers you are using. On the built in speakers on my laptop I can't hear either of the pumps, just the creaking floor from the footsteps upstairs.
I just had a similar problem but even more severe. I am using a singularity d5 pump top and I thought I killed two pumps somehow as I would hit the switch and nothing. Put in a 5 year old swiftech and it pumped water but was incredibly loud. Turns out it was the Oring. The singularity supplied Oring was ever so slightly to thin and when compressed the pump impeller(am i using that right?) would jam or grind against the bottom of the pump top. Dropped in an old black Oring and that swiftech was perfectly quiet, as were the other two pumps I thought had failed.

Hmm.
Interesting.
I've never taking my pumps apart. How difficult is it to source these D5 O-Rings?
Wait a minute... Are you talking about the one that sits between the D5 pump and the top? The big one, maybe 3-4" in diameter?

Yes, the ring between the pump and top.
WTF. That would make my blood boil.
Seems like the kind of thing that Steve @ GN would rip the fan makers on if he knew about it.

The wires aren't hooked up yet, but is anyone ready for a test fill and flush?

I'm going to try to flush with the sysprep and see what if anything happens. Might as well, the stuff was free....

Dang dude. I’m seriously impressed.That's just up front.
There is a push pull 420 up too as well
Dang dude. I’m seriously impressed.
I don't think you're missing much by having only the one radiator up top. The second radiator would be pretty choked on the fan exhaust due to the shelf.
I'll put a layer of paint on the top of the table to prevent it from rusting again...
It's this stuff: https://www.jdindustrialsupply.com/...bvycmdLx7qnaFKbcoFzFxTHyG8Wps86BoCG5UQAvD_BwEPlease don't paint the table. It's too beautiful.
I can't recall the brand, or type, but there is a dry lubricant spray, either silicone or graphite, I don't remember. But it's used on table saws and other wood tools. Prevents rust and keeps it shiny smooth.
Love the attention to detail! And pics

Wye Oil will also work
Interesting note:
My 24 fans, while not shipping from Amazon don't get the normal prime shipping right now, but arrive Inna few days, with no issues or warnings.
Aquaero parts - however - have a warning about other items being higher priority and taking longer to ship, and won't arrive for more than two weeks.
One would think that both of these were equally non-essential?
You should put this beast up on million dollar pc
I'm not familiar with that. What is it?
Alright. A few more issues, one of which leaves me absolutely dead in the water.
I'll tackle the big one first.
My Aquaero works perfectly with the six 140mm Noctua fans I moved over from my old build. They are speed controlled as expected.
It does not control my 16 new 120mm Noctua fans well at all.
When I try to control them the output looks (approximately) something like this:
0% PWM -> 0% Fan Speed
10% PWM -> 0% Fan Speed
20% PWM -> 0% Fan Speed
30% PWM -> 0% Fan Speed
40% PWM -> 0% Fan Speed
50% PWM -> 0% Fan Speed
60% PWM -> 0% Fan Speed
70% PWM -> 0% Fan Speed
80% PWM -> 0% Fan Speed
85% PWM -> 10% Fan Speed
90% PWM -> 50% Fan Speed
95% PWM -> 75% Fan Speed
100% PWM -> 100% Fan Speed
I could contine like this, controlling the fans with limited granularity, but it is also not reliable and sometimes will not work at all.
I spent hours troubleshooting. Things work better with fewer fans per port, but still not the way it is supposed to.
I suspected splitter problems, cable problems, that my Aquaero was dead (and I may have damaed it during my troubleshooting, because now PWM port 4 doesn't seem to work at all) but in the end, it was none of these things.
A visit to the Aquacomputer community forums reveals that the problem is Noctua. On their newer revision of their fans they decided to disregard the Intel PWM spec from 2005 and do things their own way. EK has apparently done the same with their fans with similar results.
The result? They work marginally as single fans, and absolutely will not work well at all controlled as large groups of fans.
I'm hoping it is not too late to get Amazon to take all of my fans back. I spent a shit ton of money on these things. And if they do, now I need different fans. I'm going to have to disassemble the loop to get the fans out, re-route all the goddamned cabling.
I am absolutely fuming right now. I thought Noctua were the good guys...
Anyone know if there is a Noctua hardware rep on these forums?
Man sorry to hear that. Going to post a reddit link to a guy with a similar fan setup. Hes a good dude and will probably answer any questions you have. Take a look at his connectivity setup:
On my build I got the fans working, but using double sided LL120s/Silent Wings 3s (2 Corsair fan/led controllers, commander pro, and 2xphantek fan controllers, splitters everywhere).

Yeah, so I have gotten through with Noctua Support. They promised me they would find a solution and requested the lot codes and information from my fans. I provided it end of last week, but haven't heard back yet. (Not complaining, it has been a weekend after all)
In the interim I have also ordered a full complement of Arctic P12 and P14 fans which are reported to work like the traditional PWM fans should, without degradation by adding more fans per channel.
When I ordered them they claimed they were not on Amazon's "non-essential" list, but they have not shipped yet, and are now estimating an arrival date of April 15th, which is kind of a bummer.
At this point I guess I will know what Noctua decides to do by then, so I'll know whether or not to return the Arctic fans.
It's a little disappointing to be cooped up in my house due tot he virus and not even have my PC for some occasional distraction, but I do understand that there are more important things to ship people than computer parts right now...
QQ are you only running one Aquero? I think you are going to need at least 2 for 24 fans.*EDIT* saw that you are using the unit that has the screen. I wonder if you just need another one of the simple aqueros that runs into one of the fan channels on it, and the simpler aquero can provide extra power delivery but still control/output data on everything.
