Antminer S9 Hydro: Bitmain's Latest Water-Cooled Miner at 18TH/s

So, Bitmain just dropped their new miner, the Antminer S9 Hydro, on August 23, 2018. This is their eighth product this year, following the S9i, ANTBOX, and Z9mini among others. The S9 Hydro is pretty innovative with its water cooling system, making it a quieter and more energy-efficient option for mining. It uses the SHA256 algorithm and can mine popular coins like BTC and BCH. The Antminer S9 Hydro has a hashrate of 18T and consumes around 1728W of power. Unlike traditional models that use air cooling, this one relies on water cooling for heat management. It needs a specific power source, the APW5, to operate. For home users, there's a S9 Hydro-Hex external module available, and for larger setups, hooking it up to an outdoor water supply can really amp up the low-noise and energy-saving benefits. This is the first time they’ve integrated such a cutting-edge water cooling design. With a custom, high-precision water cooling setup, it allows for outdoor water sources that meet quality standards, keeping the miner’s components nice and cool. During use, the chips only see about a 5°C temperature difference, which should really boost performance and reliability.

Any ideas how much it will cost? Will it include all the hardware or will we be required to source the radiator setup, fluid, etc..?

I found it on the bitmain Chinese site it costs $1,100 USD but it's china only right now (alibaba you can get them though). I am not sure if that is with the radiator or not though. You can just use water to cool these since it's using a water block but mineral oil is cheap.

Im honestly surprised it took so long to implement liquid cooling into miners from the "factory" it only makes since with how much heat is a problem. I have mined on my liquid cooled gaming PC's quite a bit and always kept them at about half the temp as my fan cooled miners. I saw that another company was offering a liquid cooled miner now but I forget the name...

Canaan/Avalon is beginning to offer them as a kit for the 841 I believe. Don't know what all it comes with though.

A lot of miners were made with liquid cooling from the factory some years ago, especially when a lot of companies made large high-power CPU-type miners. And then they started realizing that exotic cooling solutions tended to be expensive and unreliable, and high-power CPU type miners tended to be expensive and unreliable, and so now we have the air-cooled matrix of <10W chips for everything. As long as you don't try and pack multiple kilowatts into a single small box, it tends to be inexpensive and reliable without the need for complexity. Liquid cooling is only really necessary when you insist on unsustainable power density.

You get the added benefit for overclocking though. Also if this becomes a new standard or an option this would really help miners in places that are hot and humid where evap cooling won't work. I am curious if you would even need much of a pump or if just letting the hot water rise to a radiator up above would work since we know the chips can handle if the water got warm and that would mean you could pipe the outlets of the miners all together into a bunch of radiators in parallel and not have to worry about pumping if the cold water runs back down the inlet. Granted a cheap pump is probably smart to have but physics could do it all and I bet these miners could handle it. I want to buy one of these or a few to play with some setup idea for large scale cooling but I can't justify $1k on a s9 with a water block when I have s9's already.... Sell me the water block and let me drill the holes that would be nice.
