A reply to a question on Canaan's twitter account says the first batch will be end of January, beginning of Feb.

Looks like their demo shows it running at 72.4th https://twitter.com/canaanio/status/1182847955205705731

So, Canaan dropped their 11 series on the same day Bitmain revealed the S17+ and T17+. A1166 ranks at 68th with a 47 w/th A1146 is at 56th with a 57 w/th No word yet on when they'll actually be on sale. Check out this…

I think you can buy direct if you want 50 or more, otherwise, you'll need to find a reseller. I got mine from Kaboomracks, $325 each including domestic shipping in the USA.

I got my hands on a few of those Alpha Miner APW9 replacement power supplies and compared them with a Bitmain APW9. So far, it looks pretty solid. It's a bit quieter and in my testing, it used 40W less energy (2265W…

S17e also now available for Dec. delivery at $2083 but with 2 unit limit per customer. That's $250 less than the Jan. pre-order batch.

Did they drop the price before or after BTC tanked $500? Yeah, wonder if it is a direct response to the Canaan 11 series. 50th - 40W/th @ $2150 shipping in 7 days no interest for 6 months, vs 68th - 47W/th @ $2200…

These would drop right in at farms that were running old S9s at close to 1500W each.

Seriously ... How many more S17 variations can they come up with? Just trying to milk every last cent out of those 7nm chips I guess. So this is basically a 73th s17 Pro with no low power mode, so should be priced…

Um ... you say that like it's a sure thing, it is not. You might make your money back within a year, if BTC price stays high, and difficulty stays low, and your miner doesn't break, and, and, and....

Thanks for posting that it worked. Would love to see a pic of your setup. Be careful with that PSU cover off... those caps in the PSU will hold a charge and can give you a pretty bad shock if you touch the wrong spot…

Ha ... you are correct, they are 2 wire fans! I didn't pay much attention to the fans when I last opened some up, but just grabbed an APW9+ and popped it open to take a look. In the S17 video, they have the fans removed…

I believe they specifically say in the video that they don't bother removing the fans since they don't draw much power and it takes a lot of effort to open up the PSU and install fan simulators. The feedback signal from…

I believe it is safe to just let them run in the liquid. The fans need to spin or the PSU will shut down, but they apparently don't need to spin very fast. To disable them, you'd need to open up the supply and install…

How much variation do you expect? I'd suggest designing the system to keep within the PSU specs.... The specs show it can handle 47hz to 63hz ...

Here are some #s So comparing Bi58Sn42 to EP30TC from Masterbond, the solder is 6.6X better at conducting heat. That Masterbond epoxy is the best I've found so far, I think most are much worse than that, closer to 1.0…

If you try another adhesive, please post your results. Many people have talked about using Arctic Silver, but I have not seen a report of it actually working. Thanks for your results on the "black stuff" that was used…

Yeah, maybe one in a million, but not impossible... If you are looking at space in an industrial park, or an industrial condo, you might have a better chance of finding more options. If you find a place with 480V, there…

You'll need to talk to the local power company and talk to an electrition. The cost is going to depend heavily on the site. Moving from 200A to 400A probably means all new wire from the transformer, and going from 208…

If voltage drops too low 10% of the time and you shut down all those miners that drop out (144th?) every time voltage dips , even with free power that is only about $3.50 lost per day, or about 18 months to pay back the…
