L3+ exhausts a little less than D3. If D3 is 250 CFM so L3+ would be around 200.

Your issue will be not the heat but power. 8 L3+'s will use around 55 Amps so you will need around 80 Amps of power just to run them (4 20 Amp breakers @ 80%) if you have 120V. This means if you have TV, refrigerator, etc. you will need more than 80 Amps.


I'm in the uk so I get 240v mains voltage. I thinks it works out about 27 amps for the 8 L3+s (26.6666667). i have 100 amp main fuse and have not had any issues yet with internal wiring heating up etc, and had them running for a long time. I know these server cabinets will work, so maybe any suggestions for the right model or if anyone could point me in the direction of the right thread. I did see some information before but failed to bookmark it. Thanks for your help by the way

If you have and easy access to outside, you could just build insulated box with 2 openings from both ends. Put few intake fans on 1 end and few exhaust fans on the other end. There are cheap fans that can move even 3000 CFM (not the inline ones).

You could sound insulate the box with something like Safe 'n Sound. If your landlord comes you could close the ends of the box (to hide the fans) and make it like a big chest or something.
Good idea, although my craftsmanship leaves somewhat to be desired lol. I'm probably being lazy, i guess. Also got some money to burn from big profits on crypto in this last year. I have other projects with my other miners located elsewhere and I'm not confronted with this problem but I can expand further if I can convince others about a tidy setup they can host for me in their homes, or businesses. In general I'm trying to turn the majority of my money into bitcoin through mining, trading, and equipment, ready for boom or bust. A big gamble, I know  Wink

You cannot calculate the real % of efficiency by comparing the nm-shrink-percentage.
It is possible that the difference is not as dramatic as people speculate.

That' a fair point. I don't know why people expect bitmain not to mass produce a good product and moan about difficulty levels, I'm not worried. Everyone's really in it for the money aren't they?

Absolutely! Not sure why the hysteria. I don't need a calculator to believe that 16nm to 7nm is significantly less impactful than 28nm to 16nm. Frankly this appears to be a rather unprecedented sweet spot in ASIC hardware history. I can foresee a scenario where you will be able to successfully run your 16nm units 2 years from now alongside the 7nm upgrades. Or.....swap out your 16nm units at a surprisingly healthy resale value compared to what you paid. Provided you did not succumb to the siren song of the reseller at 3-5 x manufacturer's release price.

You only live once....if you do it right, once is enough.

Actually GMO claims that their 7nm SHA256 boards will produce 8TH@300W. Of course it's not going to happen tommorrow, more like 1.5 year from now.

I would have to see that to believe it. The S9 went to 13.5Th/s at 1300 w from the S7 doing 4.37 Th/s at 1300 watts at the wall. The progression curve is likely flattening at this juncture instead of steepening I would guess. Less Hashing gains with less power consumption efficiency. I could be wrong but if I am not that would truly be MIRACULOUS!!!

.....also...GMO has never even done this before right? Waaaay easier said than done!! Ask Innosilicon.....or Baikal.....or Panda.... or....well, you get the picture.

Its a 7nm chip so purely on gains from 16nm->7nm its easily believable. What the issue is with what they are doing is they are going the KNC route...large dies with crazy hash power per chip etc (remember neptune/titan?). This is definitely bound to be a disaster especially for a new company getting into mining. They haven't learned the lesson yet that large dies just don't work for mining.

Searching around I found this website AFTER I ordered my 2 L3+s for 10/27 shipping.  Anyone have any feedback on them?  They say power supply is included in price?

https://cryptominershop.net/index.php?route=product/product&path=59&product_id=51 for $1699 and supposedly in stock.  I am looking to pick up a few more after test driving the ones I get in a few weeks.  Any feedback is appreciated.

or miningwarehouses web site?

Too good to be true, I know there are a lot of secondhand on chinese auction sites but, this smells like a scam. I can be totally wrong though.

They would have to steal these to make a profit.
Why would you sell at such a price ? Even on craigslist or whatever you get better price and can stay on the couch.

Guys, I wouldnt order it ANYWHERE but official sources, 95% of miner selling websites are SCAM.
I even saw a comprehensive list of scam websites out there here on the forum, there are HUNDREDS of them. Scary. :/

Well...I guess we will see in 7-10 days as I received email stating order was going to be shipped out on 10/31 and I would get tracking number on that day.  I ordered from the miningwarehouses site and they have at least been responsive to my email questions so far.  Normally within 6 hours or so-not bad with time difference and all. 

I am hoping this works out because it would be nice to have a few racks of these running in my storage area in the attic.  Need to do some work on the venting but I am a contractor so it would be fun to put together.

Do you guys know if they would run cooler at 220v rather than 110v?  I know the amp draw is a little less (I think 4-5 amps at 220 and 6 or so at 110) but I'd have to run a 220 sub panel rather than 110 sub panel.  I like to over do things so I would just plan for it to be 150 amps total so I would have room to grow as...well, as my wife will let me, lol
