Yes. I also invite you to have a look at the manufacturing drawing I published

Yes. I also invite you to have a look at the manufacturing drawing I published 

the reason for asking is because though yr diagram states g1/4
the pictures are too small, i can't see if there are screw threads or not.

just trying to clarify that's all

This is the water cooled miner running at 325MHz now - can somebody point me on where to see if a still have potential to go higher?
What are the "rejected", what the "discarded" shares? Where do I see the hardware error rate?



That's the air cooled miner next to it:



Here are the pool stats - I don't really understand why the water cooled miner is not faster by the number the frquency is higher (~15%)

This might have something to do with the way your miner/controller talks to the boards and how it handles jobs given to chips and cooling is needed but is not that important as firmware and controller kernel design. It's brain and not muscle game.

However nice effort with aluminum blocks milling, but they suffer from same problems solar thermal panels have. Expensive, heavy and not that efficient. This technology is now obsolete with roll-bond technology available. We talk top-solutions, not mainstream which is still low efficiently-dominated on the market.

And about cooling fluid chemistry :

Most prominent vendors of cooling liquids based on "water" use this :

Demineralised water H20 + isopropyl alchocol (50-50% usually) + you can use some biological agent suppresive, like kalium - hypermangan (permanganate)  which wil erradicate algae since as I see your watter gallon bottles are exposed to the sun, and sooner or later biological agents such as algae will start to form.

Another possibly fluid for this could be Lithium-bromide, but not in plastic bottle and is also needs severe pressure protection.

Serious issue is also the electrochemical corrosion but I have too little information to help you with it.

However being put on alcohol evaporative temperature area, such bottles are not a proper storage for cooling liquid since alchocol will start to evaporate on room temperature, and there are liquid pressure issues when they change phase state, from liquid to evaporative.

This is pretty far away from reality. The vast majority of PC watercooling is done with dionised water + small amounts of additives.

Switched off the miners because of power/bitcoin price... if somebody wants it, just shoot me a pm.

One might even be able to use the cooling blocks for other miners....
