Oddbean new post about login | logout Major upgrade on the bitcoin space heater. I've replaced the three aircooled single board #S9 miners with a single board water cooled #S19 that runs cool and quiet while pumping out the heat. Used two Alphacool ES 280mm radiators, four Noctua NF14 1500rpm fans, three noctua 60x25mm fans, and an Alphacool Eisstation pump and resevior combo. This setup keeps the hashboard under 60c up to 850 watts. #plebminer #mining #homemining #decentralization #bitcoin #heater #braiinsos https://image.nostr.build/e5e3ca0d0c0bdd261a214d0c7bda2af6a0afa440bd7b2b2fc280b75f9128242a.jpg
how much would one cost? just curious.
Short answer, under $1000. Long answer. You can get an s19 95t for around $500, then the water blocks are the next biggest hurdle. You'll generally spend about $80 per board, but they're frequently only sold in sets of three. The water cooling gear is off the shelf PC cooling hardware and it goes together really easy. There are cost savings if you build more than one (I'm doing three, cause ive got three water blocks now, obviously 🤣) or do group buys. The case I'm using I built as a development box for this purpose six years ago. Its space heater life has housed GPU's, s9's, and now an s19. This iteration is the best so far.
....could a idiot pleb with some construction experience tackle this? Was it difficult to program? Again...I am an idiot
Absolutely. I picked up a used "B" grade s19 95T from @Kaboomracks and am running it with Braiinsos. The watercooling gear is off the shelf PC cooling stuff that's pretty much plug and play with some tubing. The case is something I cut and riveted together from sheet aluminum and 3/4" angle extrusions. About the most technical thing was repining the Noctua NF-A6x25 fans to two pin connectors for the power supply.
I'll also add that a separate enclosure like I built is completely unnecessary unless like me, you plan on putting it in the bedroom you share with your wife. You can get a single 480mm radiator and direct mount it via the existing s19 120mm fan mounting holes and be good to go. For packaging reasons I've gone with two radiators and made it as complicated as possible.
Love it, I'll keep this in mind when I finally make the jump and but a miner
Nice! Also, would a setup that allows you to put your wet dishes into the heat stream, simulteanously cooling the miner and drying the dishes be feasible. I think so, altough the only problem I see would be that the dishes have to little contact with the miner and thus cannot bring over the coldness to the miner.
I've dried clothes over it before, so yeah, set a dish rack on top and I imagine you'd be in good shape as long as they're not dripping.
Well it is not only about drying, also about cooling the miner itself due to evaporation of the water. Is that also possible?
Anything is possible, but in this case most likely not.
I think that if either 1) the air that goes past the wet cool dishes and than gets funneled back into the miner. 2) the dishes are in direct thermic contact with the miner 3) the air that goes trough the wet dishes and cools of also passes some heat sinks that are in contact with the miner. it might work...

Haven't worked with an s17, but if it's too noisey still you can look at water cooling it. nostr:nevent1qqsv743mqa4220wgkktz5wvt7q75c867q96uuv7v6gpwcxxh4d4jtjqpz3mhxue69uhhyetvv9ujuerpd46hxtnfdupzpxnm0jlr0vk25upsvtz3kgr7kmkycsksd0afp8vhn23d2qz6c0t9qvzqqqqqqyjwts2t
