Do you have any experience running 4 stock fan on a single S5 BBB/Base plate? I'm thinking of making a 2x S5 and i'm worried 4 Stock fan running at full speed might burn the BBB if it can't support that much power?
Your input would be appreciated.
It is tested with S7 base plate with 6 fan connectors. 4 Stock fan. S5 base plate has only 2 fan connectors. But the S7 has a dedicated connector just to itself for power? Only 2 fan connector isint an issue i would use a Y splitter. I am just wondering whether the board can safely supply the power or not.

Okay, thanks, i'll try to figure out an alternative. Maybe either run 4 at half speed, which probably equate to the same load as 2 fan at full speed?

hi, are those, model ZPDR-18V-S ? I have 50 of the 18 pins cables custom made in stock, and also some 16 pins ones for early S5s. 12" long, they were like 1$ each. if I remember correctly. There are/were for the S5 watercooled case, and some other projects, but it seems that they can serve other purposes. Edit on availability and pictures

The easiest way to bypass all the fan issues is to run them at either 7v or 5v from the PSU. It is easy to accomplish and very effective. I think making a "custom" S5+ and using some inexpensive fans like the Yate Loons would work great. Here is an explanation of running them at either 5 or 7 volts, which can be done without the switch described in the following article. http://www.silentpcreview.com/article6-page1.htmlI picked up 4 of the S7's and immediately switched all the fans to Scythe UltraKaze which are probably my favorite fans for a variety of reasons. They spin at 3000 rpm putting out 133 cfm at a low 45 db. Not the cheapest but last forever. The last point is that they are great where static pressure is an issue, such as the tightly spaced fins on Bitmain products. I can now be in the same neighborhood as the S7's and hear my family talking.

Sound a pain since you can't feed the -5v back to your PSU. Or maybe use a resistor cable? Well whatevers. I need those 18 pins cables first anyways.

It just take me to a login screen, and i can't find them on ebay using that name. If someone buy a batch, let me know i'd be interested. Even easier if you buy it to Canada. I don't know alibaba but if they can sell a batch and ship it to my address, maybe a 3rd party that know Alibaba could do the deal. Then it'd be easier to ship them out to whoeever need them. But i'm guessing this is probably what Jabberwock is doing anyways so we can probably wait until he has a batch for sale.

Interesting, I loved the Kaze's with the S5's, but I've had pretty poor experiences with them so far with the S7... The stock fans for me are god-awful, one of the pairs resonates at high speed, and makes a really pleasant constant 'train whistle' sound - really adds to the whole experience. At 55% the sound is gone, but still lurking in the background. I'm in the process of designing a ducted solution to mount a centrifugal blower - I think I can use only one and get better numbers and even quieter than a single Kaze, plus the static pressure of blowers smoke axial fans. The test blower I'm using can move 500cfm, but at the cost of static pressure and sound, but at more mellow values, like 200 cfm it's amazingly quiet. My first pass is always to get a standalone solution, then I'll look to integrate the S7 into my big plenum case - the challenge with it is the fan I chose for it doesn't have the best static pressure because the S5's were so free-flowing, there wasn't a point - I'm not sure that will be the case with the S7's. I'm also holding off to design it into the case until J4bberwock's next PSU design, since I plan to use that and incorporate it into the design as well.

did the scytre ultra kaze managed to cool this beast down? i have some of those around and i wandered if they can do the job with s-7. at full speed 3000 rpm what temperatures did you get?

I have yet to use the home depot supplies. But the metal mufflers do work okay. https://bitcointalk.org/index.php?topic=1188217.0

I would agree on the Kaze's, but the ducted blower solution I'm working on is another story - it's very quiet, but the proof will be once it's hooked up and actually performing, since I don't know how much air I will need to move with it. I actually will be taking a first pass at it this afternoon, so assuming I don't end up needing to order anything I'll post some results. Temp-wise right now I'm running them at ~60c, with the stock fans at 55%, or roughly 4000 RPM's... When I tried the Kaze's, I was seeing temps in the ~75+c range in the same environment, which was a no-go for me.

all my 18 pins cables are sold. some 16 pins ones left. I didn't expect so much interest. I'll take 200 more with my next order from this supplier, approximately 3 weeks delay. Hi I'd like to order 6 or so cables fitting S7's when available. Please let me know about details (shipping to Switzerland).

quick update 18 pins cables are now in stock. I was unavailable for 2 weeks, so currently reading all the private messages. If you have messaged me in the past 2 weeks, no need to send a new message unless I don't reply by tuesday.
I have 180 cables still in stock, so I hope enough for everybody.

I'm dealing directly with a connector and cables manufacturer who is making me those custom cables for the S5/S7. I'm buying them with larger batches of my other supplies from him to save a bit on shipping. As I said I'm not looking to make a profit on them, I'm considering it as a group buy.

Question: one miner=three connectors? Could you connect a total of three S7 to one controller? Or only two? I also see that Phil used one short connector from the second S7, so only 2 long ones needed, right? Therefore to hookup three machines you need four, not six long ones-am I right or not? Thanks.

Yes. It is possible. But this miner together with 3 cubes with one controller is slower, as three separate s7.

Thats good, i'm still waiting to hear back from you. Please let me know when you get the long S5/S7 18 pins long cables. I'd also pick up a couple of 16pin long cables if those are available wherever.

I am good for 4-6.
