Bitmain New Miner S7-LN 2.7T @697W discussion (Not official)

[Real-Duke]

I remember my S3 run mostly with around 1800rpm.
But indeed it would be nice to have a sound proof from the miner

An S3 can be kept in the same room as you with no sound woes if the ambient temp in the room stays under 75-80*.   They are super quiet TBH....  But those are <= 2000RPM fans....

So it can't really be a basis of comparison IMHO =)  He is just curious if he will need to do any special soundproofing is he buys one.

I've resisted buying one so far, but if these are quite like people are saying I might have to order one. 

[QuintLeo]

Why buy a miner that's going to be close to or totally UNprofitable in a month?

 Bitmain kinda shot themselves in the foot about these, didn't give themselves enough time to sell very many before they announced the S9.

I would love to see some more images and hear about sound level.  I'm thinking this could be more of a S3 replacement for those with "free" electricity that don't want a full bigger miner like S7/S7-F1.  Also does requires less electricity then regular S7, so again some market for it.   So i think there is a market for it, just smaller then S9.  

But once someone get's one I really hope we hear on sound level maybe even at a lesser freq and see how low it goes.

3000rpm doesn't mean anything because the fans on the S1,S3 are different then the fans on the S5,S7.
The latter have some industrial type of delta fans and they were louder at 2500rpm, then the older fans at 3000rpm.

Only way to make this quiet is to undervolt and underclock.

To stay with the S3 together in the same room better solution is/was to replace the original fans with some Arctic silent fans and max 1500rpm
Like this I have had some in my living room as heater during winter months  
Surely this couldn't be done with this new S7-LN....

3,000 rpm on the S7 is noticeably less noisy, but will you be able to sleep with it in the same room.  NO.

Where are the additional pics. from those that received theirs already?  Would like to see more, like how the power supply bracket is attached and if there's anything in the 3rd blade location or is it just empty?

3000RPM on the S7 and hashrate to 2.5Th... (have batch 6) and the miner is as loud as my PC with it's cooling fans full-tilt.... and its a dell Precision 690... Its not quiet.   But I myself an used to that sound in my room so to each their own I guess.

I have an S3 in my parents garage, and it does get loud when it gets heatsoaked.  Its higher in the rafters because that's the only location there's space, ethernet access and power.  So I can see how it would bother people and run high fan speed if trapped in your bedroom or livingroom.... But for the one in my living room, when its not at full fan speed, you hardly notice its there.  It only kicks up fan speed for a min or two every once in a while, or if I forget to leave a window open during the day.
This is what my friend is trying to see if the S7-LN is like.

 S5 fans were a FFB or similar series Delta focused flow design in the 3800-4200 RPM range - NOT 3000 RPM or even all that close.
 I don't know what the S3 used, perhaps AFB series Deltas (which ARE quieter at the same RPM but don't handle backpressure very well comparatively)?

They are very low RPM.  I never see more than 2500.

Silent at 1000-1500.

Mine just arrived. Gonna have some fun with it, but first...






Can someone confirm if that's the S2 PSU? I only ever bought a kit new, which didn't have the PSU, and neither did the secondhand machine I picked up a long time later.

Nice to see they got taller heatsinks instead of just leaving voids. That's what I was worried about. Reckon the added surface area improves heat transfer to air for quieter fan speeds at the same frequency as a standard S7.

[philipma1957]

It looks like the s2 psu to me.

[Real-Duke]

Whats about the noise he make? Btw great that somebody got one before the holidays 

[sidehack]

5-minute average 2716GH, temps 46 and 49, fans at 2880. I'm not a good reference for "how loud is this" because I have a high tolerance for fan noise; slept near a computer for the last 15 years, heated my living room with A1 Dragons and underclocked S4 the last two winters, and my desk is about 40 feet from 100KW of hosted machines. But I will say, I can't even hear it running sitting next to the S4+ (...whose PWM lines were clipped so the fans are rolling 4KRPM).

Sometime I'll put it in a quiet room next to an S3 and see how it compares. But now that I know it works I think I'm gonna do some hacking.

Awsome pics, mine arrives Friday!

[adaseb]

So does it arrive like that with the PSU attached and plugged in and everything or do you have to assemble?

[sidehack]

It came out of the box fully assembled. Ethernet and C13 and you're off to the races.

[HagssFIN]

It looks like the s2 psu to me.

I can confirm this, I have this particular PSU, Enermax Revolution 87+ 1000W in my Ant S2 (batch 4), which I still own.

it is pretty good for the watts this unit will pull.

it was under powered for the s-2.
