@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

@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.
@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
