Share your S1 stats

[norgan]

I'm interested to see the variance in these awesome little miners. How does your S1 perform for you? do you have it overclocked? What fans/heatsink mods have you got.

I'll start:

Last batch (bought may 2014) brand new, overclocked at 400~406 (depending on my mood and testing) running of a dell 2950 psu and sucking around 430w at the wall. All asic have heatsinks as do the vregs. Rear fan pushin is a thermaltake 90cfm and front fan has been reverse to suck air out. Currently it sits in a server rack with an AC duct behind it.

I found the biggest difference makers were heatsinks on the vregs (on the back, opposite the asics) and fans suited to purpose. Speaking of which - why would you go with a 90CFM fan on the back? I don't think I ran a single fan under 130CFM+ front and back.

I ditched all my S1s in the spring, but I'll see if I can dig up some stats . I will say that the quality coming out of their factory is sh!t, some miners would be ace and others complete dogs. The cynic in me suspects that they would pull the worst miners from their farm stock and sell those out for each batch, pulling only from new stock if need be.

it's just what I could get at a reasonable price. it does alright for what it is. originally I had one in my case and bought a couple more. they only cost me around $30au where the 100+ cfm fans are up to $60AU each.

mmpool.  There's 893,143 accepted shares so I'm not too worried about it

Wow - industrial DC fans are generally cheaper than PC fans, and should cost nowhere near that much. Try ebay: http://www.ebay.com.au/itm/NMB-Dell-Optiplex-GX270-Case-Fan-DC-Brushless-Model-3615KL-04W-B86-12V-2-10A-/181444763166?pt=LH_DefaultDomain_0&hash=item2a3ef35e1e

the problem is knowing what cfm they are, no guarantees.

what?

[norgan]

what?

they need to have a high flow rate. that's measured in cfm. (cubic feet per minute)

Fort he ant you want absolute minimum 70cfm but I think generally over 100cfm is recommended. I am running 90cfm fans. many case fans are only 30cfm or so.

Yes, I understand flow rate. As important as flow rate when it comes to these applications is static pressure capability. AFAIK bitmain shipped with only fans capable of at least 130CFM, although many would never achieve that figure due to the poor thermal control of the miner firmware or because the fans were worn out from extensive "testing".

I guess I was confused as to why you wrote that "the problem is knowing what cfm they are, no guarantees."?

Buying these industrial fans isn't as much of a crap shoot, and the CFM and other parameters (e.g. static pressure) are all stated - and they are expected to meet these figures by major manufacturers (e.g. dell, who uses the part I pasted earlier in servers).

[jimrome]

Well since they are no longer in stock and are pretty much obsolete, I will share some tidbits.

That's good of you. Can't wait.

The bitburners are by far the best asic miner ever so far, not one problem and ran for months between reboots at almost double their default settings.  As far as the s1's I found the early units from last year oc easily to 200 and have been running them non stop with no failures, the latter units are much more touchy in the settings and for the most part sit at 190ish, no added heat sinks fans or any other crap, they run up to 65 deg and don't care.

I found it hard to get a hold of the cfm figure for many fans listed on ebay and from other applications. 90cfm seems to be enough plus I have plenty of positive pressure coming from the ac duct. let me get a photo of it.

here's my setup for the single S1 so far (some more on the way)
