[talks_cheep]

Rumour has it that Bitmain is planning on releasing S7-F0 model for the next batch.

by removing plaque which replaces the fan.
the holes may be below.
Let 's hope it is the same case.

looks like they just replaced the back plate of the unit which had the screw mounts for the fan with the new grating as it is using the same mounting holes as the previous backing plate (right in the corners)

Then adding the Sanyo ace that I supplied for the last avalon6 group buy should fix the issue.

you wont be able to mount it with screws but i think small zip ties would work to mount the fan to the grate.

Any word on the specs? How often do they release new batches?

his comment of an s7-f0 is a joke. saying that the current version (16) is the s7-f1 (one fan unit) with the s7-f0 (being 0 fans).

but as far as batches. they seem to have a new batch lately every 2-3 weeks. Seems to be every production run is a new batch. ie they have 1000 made and thats 1 batch. then another 1000 and thats another batch.

Thanks for the clarification. I totally fell for it.

4500 rpm (two fans) were producing incredible noise at >=72dB.
I wonder how 6k rpm fan sounds like?

Noise    64 dB(A)

OK, thanks, it is very helpful, but I find these numbers by manufacturers to be understated by at least 4-6db.
I checked multiple fans before and "real" number during mining was always 4-6db more than what was stated in the specs list.

[in2tactics]

otherwise I suppose that have be replaced by two silent fan.
3 pins it will not thermoregulate, let's always 4500 ..

30euros so 35usd (both)
17.9 db max.
must be able to find better.
but already big drop.
I wonder if the garanty bitmain still stands after?

That Noctua fan you linked is only 40mm. It simply does not cover enough area. Besides, it only moves 8.2 m³/hour versus the 120mm Delta fan which moves 5.96 m³/min. That is why it is so quiet.

So we're thinking this 6000 rpm fan is quieter than two 4500 rpm fans?

the unit will be loud maybe lower then the two 4500 ones but loud

Downclock from freq 700 to freq 625  will most likely prove the best way to use this miner.

 I may order one just to see if I am correct.

[generalt]

I'm tempted to order one myself but I'm trying to hold out for a review on the noise and the heat first.

[Legacy2005]

been tossing around the idea of getting one as well. waiting to see the results for heat issues. since the backplate has been replaced you cant attach a fan easy. would rather not have to downclock it just to keep it functional. for that ill get an Avalon.

maybe they will realize the error of their ways and the lack of urgency to purchase this version and bring back the 2 fan in version 17.

So, just got the S7-F1 hooked up and running. Temps are low today, in the 60's so I went ahead and let it ride at 700 and it's holding steady at 59c on the highest blade with .0005% error rate. Going to let this go for a bit as the temps will rise into the 70's next week. I will keep you all updated on how it goes. As for the noise it does seem a bit quieter than the others but since they are all on the same rack it's hard to tell.

Also, the packaging was all updated, new foam, smaller box etc... So this was definitely not just a stop putting one of the fans on redesign

Thanks for the update. I'm very interested in seeing how they perform.

That's good to know. I will get my S7-F1's a few days later.

What are your thoughts on the overall build quality? Was it comparable to previous batches or better/worse?

I would say it's the same. Time will tell though...

what/how does the backplate look like. is it a completely new panel or did they slap the grate over the old one? (can you screw mount a fan to the back?)

If possible many of us would love if you could post some pictures of it.   If you could get all 4 sides and a few extra shots would be a great addition to this thread.  If you have a decent camera please think of this

As soon as I get back to the house tonight I will do that. The backplate looks to be a new panel. Does not look like it will be easy to add a second fan, there are no pre-tapped places to bolt it to anyway... you might be able to take the backplate off and attache the fan to the plate with some washer/nut combo then reattach the plate but that would be about the easiest way I could see of doing it.
