What do you think about this BM1373 latest miner

[Somegory]

After following a forum members lead I am shocked at how efficient this new miner is  
This new Bitcoin miner has the BM1373 chip which is more efficient than the BM1370.



I am so tempted to add this to my collection right now, but since no thread about Bitfortun miner on the forum I need to ask how the performance truly is and what the experience have been so far.

Anyone running Bitfortun Asic miners on the forum?
I guess this is the latest most efficient chip right now? Or something new is out?

Please kindly drop review if anyone has this miner or this brand running.

I never hear this Bitfortun brand and even https://www.asicminervalue.com/ doesn't list of any of their ASIC. It must be really new or obscure brand. But other brand also have announced/released miner that use this chip, such as Nerdaxe Gaia and Bitaxe Naja.

I guess this is the latest most efficient chip right now? Or something new is out?

That should be the case, since same same used by Antminer S23.

And Hammer Miner Thor P2 use 2x BM 1373

And Hammer Miner Thor P2 use 2x BM 1373

Bitfortun OctAXEy has 8x BM1370 chips using 155w and producing 9.6TH - 10TH, similar hashrate to the Thor P2 but older chip, what is my point here? That how many chips is installed running doesn't matter that much.

Where efficiency takes the lead for some, price per this miners is what others care about, the 20TH Bitfortun is not available everywhere right now, if anyone can't wait then getting two Thor P2 makes a lot of sense.

I just watched a few reviews on YouTube and surprisingly it's not that efficient ^{[19.4 J/TH]}: e.g., the numbers on this "screenshot" are close to what I've seen in those videos ^{[Magic Miner 40T uses 30 BM1370, whereas Bitfortun BS-4 uses 4 BM1373 chips]}

A couple of issues from those videos:

• The 350-watt power supply that comes in the box isn't good enough for long-term use ^{[no safety headroom and even at stock, this miner was reaching 360 W, so you have to underclock it a bit]}.
• Loose fan header connection because of the 3D-printed stand ^{[there's a small chance that it'll lead to an issue, but the risk will always be there if you don't try to at least slightly modify the stand]}.

I'd like to point out that despite AIOs being great for the cooling part, they tend to have a short lifespan ^{[unfortunately]}.

Thanks for your opinion SFR10

Can you please help me with the video link? I understand your advice and it's acceptable but I will like to watch the video myself, maybe just for fun of it? Thank you..

If this miner is using 360W then the picture is very misleading, I was praising it because they said 200Watts, and about the bad power supply that will be extra cost because it's better to buy extra PSU for the miner than risking a bad made one that can catch fire anytime.

I've also never run an AIO cooler that later died on me, I have two miners using AIO coolers and also my PC which I've been using to mine Pearl coin for a while now, this is a PC dated back in 2022 and it's still running.

Do AIOs give up the ghost just like that? Weird, never seen one died on me but it's ok, thanks for the information, much appreciated.

If you’re asking miners for advice, don’t rush to buy a new device for solo mining until there are enough reviews. It’s very difficult to create something truly innovative these days, and I see no point in purchasing untested models there are currently more offerings on the market than there are buyers.

Sure, here you go

• The BEST-LOOKING Bitcoin Miner Yet?! Bitfortun BS4 ^{[a bit long, but it's worth it (from the videos that I've watched, he's the only one who pointed out the issue with one of the fan headers)]}
• Brand NEW 18 TH/s Home Solo Bitcoin Miner!

Has been a while since the last time I used my PC to mine a cryptocurrency ^{[back then, DigiByte was quite profitable for me]}, but as a gamer and someone who also does heavy rendering, I've already had three dead AIOs ^{[two of them were fixable, but the cost would've been close to a new one, so not worth it]}... Maybe I'm cursed or really unlucky, but that's why I'm no longer including them in my setups.

It's very strange that you used an all-in-one PC for such tasks. I see that many all-in-one PCs overheat during office use, and if they aren't cleaned and the thermal paste isn't changed, they'll die in 3-4 years from overheating, and repairs will be very expensive.
Maybe you should try buying a good case with cooling and building a system unit that will last you 3-5 years.

I wonder if the inefficiency is due to overclocking. I don't find anything from Bitmain website, but multiple website claim 1 BM1373 chip have "default setting" ~2.5 TH/s and ~25W.

It's probably why mini PC getting popular for office and business these days. It's still cheap, easier to repair/replace and usually you can vesa mount it to monitor you already own.

You have a point, but it appears there’s a misunderstanding... I was referring to all-in-one liquid coolers, not all-in-one PCs.
^{- FWIW, I tend to upgrade the important PC components faster than I should normally reapply thermal paste (depending on the paste and how you use your PC, I believe it's 2 to 5 years) and I dust off at least every 2 to 3 months.}

That's probably the main reason behind the strange numbers that I'm seeing versus some of those somewhat misleading banners on the internet.

While mini PCs are indeed cheaper to purchase than standard PCs, they are far more expensive to repair. Overheating often causes the chip contacts to deform, performing a reball  or replacing the chip entirely is a very costly repair. Furthermore, a reball typically comes with only a minimal warranty, usually just a few months, while replacing the chip with a brand-new one often ends up costing more than buying a whole new device.

Liquid cooling is generally advantageous for industrial-scale mining, but for home mining, it represents an additional expense—even if you are an engineer and build the system yourself using materials purchased from a plumbing supply store.
