Sidehack does not do pre-orders. Personally, I have always felt that taking pre-orders without a proven product is a highly unethical practice.

The miner is a work in progress and until his products are built, tested, and parts sourced for production he does not offer them for sale.  

Since you are using the latest controller firmware you probably also need to update the latest miner firmware (MM). In the past I've found that they need to be matched to each other or the miner just does not run.

Now as to where the MM firmware is on the Canaan site... Since they redid the site I've no idea 

Not a bad idea but - what happens if you are not drawing hot water from the tank? It is going to keep get hotter and hotter...

Do be aware that 'low noise' usually also means that they are NOT rated for delivering high pressure. That mass of tiny heatsinks in a s9 presents a lot of resistance to airflow so the fan must be rated for high static pressure to overcome that resistance.

Also - not a good idea to bypass monitoring the fans. If they fail you can fry the miner...

Nope. Just Not Fuzzy & Warm 

So how goes finding folks for a new Lottery run?  
Actually mainly just putting the thread title back to normal. While I'm not a fan of the pool it had to be done...  

Do not forget that mining is a Financial endeavor and software/hardware MUST be properly vetted to be sure it works properly. A decent developer will do that by running it on their own network before releasing it to the world.

One does not just write code, see that it does not crash and then announce "it works!" You the developer should provide proof and NOT put others at risk by making them be testing guinea pigs.

Or they could just look at the pool home page. There it is, posted top center of the page...
Maybe that is too difficult or complicated for them to figure out?  

Bitmain headhunting TSMC engineers makes no sense. China has no advanced process foundries (under 10nm nodes) and will not for many years. It is impossible for China to produce needed EUV steppers and other critical parts it takes to produce those chips.

Considering that Bitmain and other mining chip vendors already have in-house custom layout designers as part of the 'Secret Sauce' that makes a successful miner chip perform so well vs one that uses standard layout IP libraries I just do not see what knowledge they are trying to gain.

I define Professional as one who's been formally trained in what they do and made a career out of it. Even more to the point, it is someone who cares about the quality of their work and if there is a problem - they fix it.

Given that, he is programming hobbyist. Not without some talent, but nonetheless still just a hobbyist.

The problem is that -ck just does not care about it anymore.

You have to remember that -ck is not a professional programmer: He is a medical doctor, specifically an anesthesiologist so bitcoin stuff is mainly a hobby for him and as a result he stopped updating/fixing cgminer & ckpool quite a while ago... The one other main coder for them was Kano who IS a professional programmer and several years ago due to irreconcilable differences over proper coding techniques and testing of said code -ck booted Kano from the gits

I agree 100% which is why I pointed out that it was a long time ago I used them. Once concern over the years since then is that MyRig was a distributor of the Halong Dragonmints which was quite the shit show.

Everyone who files taxes in the US will get the Stimulus check. The only catch is the Gov needs to know where to send it. Since the Gov only knows that by referring to your tax forms - which will also tell them how much the check will be for - if someone does not file taxes then just how is that the Governments fault?....

You reap what you sow: The OP prefers to be off Gov radar by not filing taxes (a W2 form is NOT required or expected if one is self-employed but you ARE still required to file a tax report) so...

Correct. The key point is that you should NEVER connect more than 1 PSU to a hash board. The power supplies will fight each other and eventually 1 will fail or worse yet you may burn the PCIe connectors.

MyRig is not Russian. It started out at the Colorado location as a Bitmain Ant farm around 2014. It is (or was) ran by Yoshi and at one time was a Bitmain distributor for North America.
I used them long long ago for repairing s7's and a couple of my s9's from batch 8 & 10. At least back then they did very good work .

Melt the PCB? No. They are made of FR4 fiberglass & epoxy resin. That stuff cannot melt.
The solder however, being lead-free its typical melting point is around 217C but the reported chip temp is still below that.

If temp is really over 180C then the board would discolor and char. Also a safe bet that the chip would be dead by now from semiconductor failures in it.

Historically Canaan has always had temp sensors inside of each chip (hence the per-chip readout) so considering it is otherwise running normally I go with the idea that it is a false positive.

Any of the handfull of sha256 altcoins. Aside from a lottery miner it is highly under powered for mining Bitcoin.
This is the Bitcoin-only area and discussion of alts is not allowed here - use the altcoins area here

Terribly bad. They have a very high failure rate.

Because the fans speed is controlled using a PWM signal, possibly but not certainly. With PWM control all power switching to set speed is done in the fan itself, the controller just supplies a low level control signal to the fan.

The concern is the size of the circuit board traces feeding the fan(s) carrying the +12v and return for it. If they are too thin they may burn up.

No it won't work. Without the tach signal the miner will think the fans is not running. The PWM control is not really an issue assuming you don't care if the fan always runs at 100%.
