New one fan S7

LOL they put a warranty sticker on one of the screws:

As you can see the ~1mm thick grille is screwed into the case just like the front plate to which the fan is attached:

To properly attach a fan to the back you would need a similar plate, or perhaps long bolts with large washers could be used through those hex holes.

But to avoid issues with the warranty I think I would just use strong zip ties.

Miner is not mine (pun intended) and sorry for the greenish pictures, crappy phone was all I had.

Edit: forgot to take a pic of the controller but there is a 4-pin header for the second fan.

that confirms what i assumed. a whole new backplate.

might be able to put a fan on there if you use zipties instead of screws. Find some thin zipties that will fit through the rear screw hole and ziptie it to the grate.

Thank you for posting I wondered what they would look like.  I am not sure what to think of new blackplate with warranty sticker.  It does seem adding a second fan like I thought might be a good idea... will void warranty so crappy idea.

Guess we will see how they operate with new higher RPM fan.   Hopefully it all runs good and 2nd fan we see is not needed.  I don't have one to test out but some might be like my mining area using lots of CFM's to cool miners.  Hopefully if one would fail in my mining area the CFM's from big fan's would still keep it in a safe zone.  Or at least allow it to safely turn off without getting horribly hot.

 So I know how to attach a fan with no damage to the warranty sticker


http://www.mcmelectronics.com/product/83-11829?

then use 3 of the four included screws leave the warranty one alone

put a grill on the other side of the new fan with four small thin zip ties.

this fan from amazon is good

do you need to do this ?  I have zero clue

but I think if you do this the machine will be easy to over clock

The grille screws are about 120mm apart, but the distance between attachment holes on a 120mm fan (and the spacer probably too) is about 105mm. You can see the difference in my second pic. Unless I misunderstood what you're suggesting.

Okay back to the drawing board.

Well four zip ties to the grill and the gasket may work.

Yeah simple and cheap and I think good enough to last until doomsday (aka halving).

So I will have a couple of fans from S5's that had bad boards. I think I should be able to re-use one of them as a second fan for the Batch 16 S7?

At any rate, I will probably buy a couple, so I'm grateful for this thread.
Also have a few coupons I can't use. Asking .04 BTC. PM me if interested.

[babycicak]

I just received few miner of the 1 Fan batch.
After testing and setup, the fan run at full speed 6000rpm. It's REALLY noisy.

I'm missing the 2 Fan batch now.

[Legacy2005]

will be interesting to see how they handle as you add more and ambient heat increases. board 3 is definitely a bit hotter then the rest, seems like the fan isnt hitting that area as much


how is it running? within spec and low hw errors?

[mtmining2]

Well supposed to hit 76F here today and i have one of these one fan units and two of the standard two fan S7s running in my garage so we shall see how it does. It's at 700MHz currently cause it's been rather cool but I will be watching throughout the day and adjusting if needed. Will post back with what happens.

[mtmining2]

So outside is ~71F and the miner is holding with two blades at 60c and one at 56c. Clock still 700 and fan at 5400 hardware errors at .0007

What is ambient in the room its running in? how many miners are running in that area?

[mtmining2]

can't know for sure as I am not there but it usually sits a few degrees above ambient, it's a garage with a box fan in one window sucking air out and the miners exhausting toward the fan with another window open to let air in. Nothing fancy but it ventilates fairly well. There are two other two fan S7s in there with it.

[babycicak]

To install another Fan you need to un-screw all 4 screw. In this case, the warranty is void. 
Look good, after install second fan. The noise is about 75 dB, temp about 63 degree. Room condition is about 28-30 degree.

[KeezAZA]

Damn that is loud! 75dB.WOW! going to cry with this one.

[Legacy2005]

how secure is it? does the panel go back on flush?

are you able to use smaller zipties and tie it right to the inner grate pieces?

A few quick observations on S7-F1 / Batch 16:

- The heatsinks have changed. Specifically, the package-side sinks (the tall, lighter colored ones) have thinner fins and have a T-top central fin like the darker sinks. I believe the new design means less of the air path is obstructed and theoretically that means lower pressure drop through the box. I think this is the primary design change enabling single-fan operation.

- The hex grill on the exhaust side has obstructed columns, presumably to influence airflow patterns further back in the box. The grill is asymmetrical and has small notches along one side to indicate alignment with the hash boards.

- The silkscreened version text on the hashboards still reads "S7_SP0WER_HashBoard_45_V1.3" as it has at least since Batch 8

- The controller boards are still labelled "S5+_CtrlBoard_V1.6"

- The fan header for the 2nd fan is still present.

- The shipping weight is down to 7lb14oz or about 3.6kg; the new boxes are 35.8x21.5x25.5cm, 4.2cm shorter end to end than the two-fan boxes.


I'll get pics and look for other labeling or component changes as time allows.

I am thinking about purchasing an S7 but not sure to go with 1 fan batch 16 new or look for a used model that has 2 fans?

I am also wondering if a multiple atx psu configuration is capable of powering this miner like the S5?  Older models seem to call for around 1210 and the batch 16 seems to be around 1300.  I was thinking of using 3 750 gold thermaltakes, 1 for each board, does that sound doable?

[KeezAZA]

You will need 10 PCIE plugs.
3 per board and one for the controller.

Currently in SA we are moving into winter.
Temps range from 17-30C ambient.
My S7 F1 is running at 66-68C most of the time with little outdoor air intake.
Set the fan to 80% (4800rpm) and the temps run up to 71C.
