Have to get this off my chest, we got a replacement bracket some 2 weeks back .. which again did not fracking fit, same as the original part we had! Need to raise a question, have you tested the brackets? We were not going to wait another 4 weeks to get the third bracket, so we went with a totally another vendor for the CPU block.
To add pain to this rather slow episode, last Friday, this
flow indicator with filter G1/4' cracked from end to end, with multiple smaller cracks in the middle (and I cannot say that the fittings would have been overtightened, when I went to take it out, I could EASILY open both ends with fingers only.) I would have taken pictures of the indicator, but my colleague took it and mashed it with a hammer on the spot.
Since we replaced the CPU block, for the week he had been configuring Proxmox and multiple virtual machines for a Kubernetes setup, when he had heard this weird snap or a pop from the open enclosure and the system froze half a minute later. Inside the enclosure, he saw water drops running on the tubing and immediately went to the power switch in the back. We don't know if the sound he heard was the indicator cracking or something on the motherboard, which at this point does not really matter, the crack had ended up leaking to the motherboard, destroying it and along with it 128GB of memory, total damages being around 850 EUR. Now we also have ~400 EUR worth of water-cooling parts, which we are really "afraid" to put into any use. By some miracle CPU and everything else that was attached to the motherboard were still tested to work fine.
A quick tip for anyone else using the same indicator, make sure the tubing from the indicator does not let the water flow towards anything important. Our mistake was that once the crack happened, the water run on the outside of the tubing downwards and was dripping from there to the motherboard.
We were in hopes to use these components to build a series of home lab servers, but this was not at all what we expected quality-wise. Also, this was not our first design built with water-cooling either, the first series we built back in 2001.
This project we started designing already in March and thought would be hardware-wise finished latest at the end of May (with component shortages and delays), and then be finished with the software side in early June .. now it's back to thinking if we are comfortable using any cooling parts from this build.
And apologies, I absolutely hate writing about this sort of thing, and I usually don't, but the frustration level just exceeded a threshold level on our end .. poor choices happen, and we learn.
