okay! check out this cutie. this is the new CI/build server that i've been assembling for the last month (hard drive for scale, there are no hard drives inside)
- Chinese X99 motherboard (excellent)
- 20-core Xeon E5-2630
- 64 GB RAM + 32 GB swap on Optane
- 2.5 Gbit ethernet
- 3840 GB of NVMe cache
all in a tiny and more importantly quiet envelope
@whitequark what are we building!?

@k mainly a bunch of C++/Rust projects for myself and friends

anyway this is the imouto
the oneesan is going to be a 128 core dual Epyc 7763 machine with 0.5 TB of RAM
that one i plan to offer to the open source community as a way to help leaving GitHub

it sounds really exhausting (well, really loud mainly. it is supposed to be exhausting) to be removing a maximum of 600 W of heat with a server flow-through cooler so i'm thinking about rigging up a liquid cooling setup somehow. i don't know if anybody has stock water cooling blocks for AMD SP3 socket but i think i can just do some machining and make waterblocks for it?

@whitequark yeah you can get sTRX/SP3 compatible water blocks

@gsuberland anything to watch out for?
also, what should i use as the coolant? i don't want potential water leaks on the very expensive to replace setup, 100% glycol maybe?

@whitequark have never personally built a water cooled machine, but I have watched enough people do it to offer some general advice:
watch out for corrosion from mixed metals.
for a pump I recommend the D5 since it has proven to be a workhorse. running two in parallel gives redundancy and better performance with restricted flow. flow alarms are helpful, too.

@whitequark I have a spare Heatkiller 4 sTRX4 block which should work but pretty sure shipping it to you would exceed the cost of a new one given the current... international trade clusterfuck. ( https://shop.watercool.de/HEATKILLER-IV-PRO-for-Threadripper-COPPER-NICKEL_1 )
Most of the pre-mix coolants are water based but do have additives intended to reduce conductivity of the coolant to reduce the potential impact of leaks.

@malwareminigun i don't think shipping to the UK will bite (it's for personal use, no?) but i'd need two... i could buy a different (cheaper) one on aliexpress for 65 GBP each

@gsuberland bykski d5?

@whitequark fluid wise I don't know if glycol will end up being too viscous to flow well, especially through skived microfins in water blocks.
most people just go with water plus a corrosion inhibitor + biocide additive and hope for the best.

@gsuberland could always fill it with galden haha

@whitequark the pump itself is a D5, there are tons of different manufacturers selling pump units that integrate them.

@gsuberland what... does D5 mean here? model number? size?

@whitequark if you use distilled water and an additive it's at least not gonna instakill your board if there's a minor leak tbf
I've seen builders get away with absolutely soaking boards and then just waiting for them to dry and carrying on.
main thing is just making sure you have no slow leaks that will cause problems unattended.

@gsuberland hm yeah you're right, i could verify the conductivity of the water to be in Gohm range and then it's likely fine; plus I'm not aiming for aesthetics so i could teflon tape the everliving hell of every connection
-

@whitequark it's the short name for the actual pump component used inside the thing.
what you buy is the pump in a housing with the right fittings for watercooling and an adapter for some standard pc power connector. lots of companies sell them, it's sorta like system integrators but for pumps I guess

@whitequark @gsuberland well conductivity of the water is part of the issue but also pcb cleanliness. If it's covered in domestic dust full of salty skin flakes etc then DI water leaks will still result in conductive runoff
