I would like to water cool an Antminer S9 with water blocks that were successfully used on an S5.
What are the hashing board dimensions for the S9?
Thoughts/suggestions?

The boards are a different size and have no mounting holes. You'd have to remove the chipside heatsinks without damaging the chips, and probably do some milling on the waterblocks to provide space for any chipside components with clearance problems, and then figure out how to mount the boards without shorting out or damaging anything on the PCB backside. Overall, it's not impossible but prohibitively difficult and generally a bad idea.

Hmm, I didn't realize there were no mounting holes. Do you know what the dimensions of the actual hashing board are?

With the R4 being much quieter and lower hashrate, safe to assume we'll see the 11.8TH/s S9 priced below $1,350 next week?

there are holes on the s9 board, look & see carefully but totally agreed, removing the heatsinks will be a VERY painful task & high risk but if 1 can custom make a heatsink plate to be mounted on top of the heatsinks would not be such a bad idea imo but the question is, is it worth it at all to do so, most likely no . . .

Do you know if the holes line up with the same holes on the S5? And if anyone owns an S9, could you measure and provide the dimensions of the hashing board? Thanks

Depends on if that $1000 price for the R4 turns out to be correct, I'd guess.

I'm also interested in watercooling S9 or R4's.. Winter is coming and few years back C1's were warming my house nicely.. Now I have kept pump and big radiator from that time and would be fun to build something again.. So if someone manages to build some waterblocks for S9 or R4, I'm interested ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

I think the S5 water blocks should work but I need someone who owns an S9 to post the hashing board dimensions to confirm. Anyone?

Dimensions aside the #1 problem will be dealing with the heatsinks glued to the tops of the ASIC's. They cannot be removed without GREAT chance of damaging the ASIC's. That leaves using some kind of thermal putty eg the kind Berquist sells to push into the fins and make the contact with a cold plate. That stuff is $$...

Do you know what kind of glue they use? My main goal with water cooling is to get the S9 to run more quiet. The R4 is quieter at ~52db but also costs $162/THs vs the S9 at $123/THs. Any recommendations to get a quiet S9?

They use thermal adhesive but it is difficulty to guess more specs about it. Probably some Chinese thermal adhesive. The one that comes to my head first thing when someone says thermal adhesive is Arctic Silver Thermal Adhesive http://www.arcticsilver.com/arctic_silver_thermal_adhesive.htmSo there's an example of thermal adhesive.

Any recommendations to get a quiet S9? Bitmain did not specify 52db at what distance so there's gap to be confirmed. You may also consider immersion cooling but I don't know if anyone has done it with ASIC miners at home.

Since the oft referred to generic Mineral sucks on many levels and DI is right out that leaves using fluids made for electrical equipment cooling. eg http://www.cooperindustries.com/content/dam/public/powersystems/resources/library/900_Fluids/CA900001EN.pdfLike the Shell Diala-AX we use in lasers it is reasonably priced, I believe for a 55gal drum of Diala we pay $750 USD. Biggest issue with Diala is that it strips the polymers out of many plastics - especially PVC as in what most PCIe power wires are covered in. PVC starts going rock-hard in weeks. All plumbing must be metal or a plastic/rubber that will not be attacked. Same applies to using Mineral oil but it takes longer. In every fluid or oil I've come across any labels or stickers will soon be floating around... Acrylic eg Plexiglass(tm), polycarbonate eg Lexan(tm), Nylon, Polyethylene, and fiberglass/epoxies all hold up with no issues. Might want to look up the mfgr specs on the large can capacitors used to see what their seals are made of. If silicon rubber, most likely ok unless silicon fluids are used. If is a different rubber compound need to verify chemical compatibility of it with the fluid used. The other thing that need investigating: All thin engineered dialectic fluids are designed as penetrating oils to get into the tightest places. Experience proves that o-rings do not stop it so not sure if it can affect a 'solid' electrolyte can cap. Usually near water thin so easy to pump, good heat capacity and flows well over the heat sinks. As a viscosity reference, water is 0.890 cP edit: Hmm. This looks rather interesting http://www.clearcoproducts.com/dielectric-silicone-fluids-sto-50.html and http://www.clearcoproducts.com/pdf/dielectric-fluids/Dielectric_Properties_Pure_Silicone_Fluids.pdf"inert to all substrates" Available in 5gal pails or 55gal drums. I may get a 5gal pail to um, investigate using something other than Diala (very restricted shipping regs, hardens the laser cooling lines). Yeah, thass it. To improve ease of laser maintenance... ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

Definitely operates differently than Novec. Novec is a 2-phase system with most effective heat transfer happening when it boils, other fluids are just absorbing the heat to be pumped/removed elsewhere. Far from cheap but it is still far cheaper than Novec. I am getting quotes from Clearco for a couple different fluids, The ST-50 oil is ~$30USD/gallon when purchased in 55gal drums.
