re: solder bonding of heatsinks vs using thermaly conductive epoxies.
There really is no comparison in thermal performance and I'd bet 10x is a low guess. Any sort of direct metal bonding is far superior for transferring heat. The mechanical aspects however obviously can be problematic.

So Bitcoin is thought to maybe go PoS after... Thought by who? Links to the sources of your speculation please... Certainly not by anyone who understands what Bitcoin is and what it brings to the table by using PoW. It will be a very cold day in Hades before Bitcoin is changed to PoS. More to the point -- applying the required fork means it would no longer be BTC and instead would become just another Piece Of Shit altcoin. |

I find it mystifying to see how much people care about the government, or about this or that becoming "mandatory".
Does anybody give any thought to the fact that you might DIE from covid?
I have two dear friends who got covid. Husband and wife. Husband got it at work, and contagied her. Fortunately, they both survived it, but they both got sequels for the rest of their lives.
So, who cares what the government says? If they PROVIDE the vaccine, I will provide my arm. And no "rebellious" BS or stupid conspiracy theory will change that.
Despite what all the "Internet Infectologists" keep saying, I have already gotten both doses of the vaccine, and I'm still very much alive and kicking. So I rather trust the real experts. Ditto. My GF and I will be getting Moderna booster shots next month.  |

@OP -- links to source of your speculation about China back peddling on the ban that they imposed earlier this year?
Without links your post just a random thought from a random person...

As long as the duct fans are rated to deliver that airflow under pressure, sure. The fans on miners are so loud because they have to move the air against a fair amount of resistance (back pressure) caused by the heat sinks. That entails using fan blades with a steep pitch moving at high speed to generate enough pressure and that is where most of the noise comes from.

Can we at least assume it is plugged into 208-240VAC?

I registered kano pool.Account->settings led me back to homepage and logged me out, so that I couldnt set my payout address.What should I do?(solo account)
And I got booted from kanopool's discord group moment after joining, what is going on man?
Everything else is ready except for this account setting problem.And why cant I join discord with kano. Did you read the instructions on setting up the solo act? If you also have a regular PPLNS act there the solo one must use a different username and payout address. eg, my main acct is Fuzzy and solo act is FuzzyWuzzy As for discord - read the pinned message at the top. By default Discord only gives a 10min period to post after you use the invite. You need to have Kano assign you a miner role to stop Discord from kicking ya out. |

That has to be your call and for me would depend on what the power company will charge you for it and the lead-time. You can always look for a building with 3-phase 208V 800A and use buck-boost xmfrs to raise the lines to 240V... @Phil, in the summer we run two large 5000 cfm fans blowing on the 480 trannies (no. puns) Why? Because they get uncomfortably hot to the touch? That is the nature of the beasties. Check the nameplates and you will find that the insulation is rated for probably 180C and a temperature rise of at least 100C over ambient. Unless you can literally cook an egg on them they should be fine. |

RTFM! Yes the miners use 208-240VAC. Why do folks keep asking about 120v when they are clearly spec'ed for 208-240? Hell, it's even stamped on the PSU, can't they read? As for where you got the idea that 2x 120v outlets might = 240v, that's one I've never heard before.... huh  If you are in North America you need a L6-15 or L6-20 outlet at the wall. A L6-20 duplex outlet (2 sockets) fused for 20A and L6-15 ends on the cords would be perfect as it protects the miner by having both power inlets protected by 1 fuse/breaker - no chance of blowing one feed while the other tries to stay alive... The C13 end is correct but frankly 18ga wire is too small, I prefer at least 16ga with 14ga cords being ideal. |

Another advantage of course is that using multiple xmfrs lets you power down smaller blocks of miners if the power feed to them needs attention or modification. They will of course also still need to supply a modicum of 120V service for general building usage such as lighting, office outlets etc.

In the US I can guarantee there is not a 415V transformer 'nearby'. You would have the standard 480V and as a wye connection that produces 270V between each leg and neutral.

Good day, first of all, i recently join this amazing helpful forum, would like to thank developers and members who help others finding solution you guys are amazing. second, i am having the same issue, from my humble understanding if the control board is hack you will not be able to use another firmware, i have successfully managed to use back the original firmware from inno after trying several firmwares until i found one which override the previous one, anyhow when i try to change the pool it says successful but in the bottom it says please note miner is using fixed pool setting. latest i came to know i need unlock firmware if any has it please share it if anyone can advise how to remove this setting, i've been trying for a week now  many thanks I take it you bought the miner as used/refurbished from Inno? Those were pulled from farms that were in China and many of those they sold had been locked down to prevent hacking but the locks were never removed when they were 'refurbished'. Ref this thread https://bitcointalk.org/index.php?topic=5355134.msg57751708#msg57751708You will need to contact Innosilicon who will send a bit of software to get the DNA id of the miner, you then send Inno the data and they will provide software to unlock the miner. |

... 3. Bitcoin may consume as much energy as all data centers globally - so what? Why is the data center that is spending 80% of its energy to power useless gossip is not waste? We absolutely don't need to waste our time reading such biased portals by paid shills or dumb reporters whatever the case may be. Energy to mine bitcoin is not "wasted". That way energy to produce and procure special type of paper, watermark, printing is also wasted. The energy to melt metals and create amalgams and seals to mint is also wasted with the same logic. How about the energy to build and secure mints run by government? I am not even getting into the energy used to keep this system going and the energy this kind of shill media is using just to run misinformation campaign. Why don't these shills talk about that? They really got the vs data centers power backwards. As has been pointed out in other threads regarding POW energy usage, over 85% of global data transfer/storage/ etc power usage is video streaming services (including porn services which makes up a large part of that)... Cambridge Research put BTC power usage at about 4% (?) of the total power usage. It is still a huge amount of power being used and yes, more power than many small countries use. Then again, just 2-3 large aluminum smelters also 'use more power than many small countries'. It is a drop in the bucket vs other data-based enterprises. |

What I was wondering is what is most likely to damage the chips?
Overheating due to not enough cooling?
Or
Over-frequency / over-voltage? Overheating is the chip killer. As to what can cause it: 1. Insufficient cooling 2. OC/OV coupled with poor cooling. All OC/OV does is increase chip temperatures but provide enough cooling to make up for that and you are good.. |

What self-respecting country would implement such a scheme? Even more to the point - who would oversee it and how would they be able to force a country to use it?
Me growing wings to fly and spitting diamonds is more likely than the OP's 'mandate'.

Look at wallet.dat my money they have to pay me
...
Is this person alive
The amount is very small, 56 dollars
I want him to tell me the truth
And I'd like to grow wings, fly and spit diamonds. Don't see that happening either.... |

For miners with fans on both ends of them, just because a fan spins does not mean it is working. Air being moved by the working fan will make a dead fan spin but of course the dead fan is not actually helping to move the air and in fact slows it down a bit.

Perhaps if you read about what Taproot is and does you'll understand the implications. AFAIK non-taproot blocks will be rejected by the majority of nodes as they have all updated to the latest version of Core that triggered it. |
