'The right to privacy matters'

Quote from: Swimmer63 on January 14, 2015, 11:12:20 PM

Phillip how many watts are you pulling at 1300 gh/s?

670 watts

670/1300 = .515 watts per gh

one thing I like about the s-5 is the power is between .49 - .52 watts.
I tested from freq 200 to freq 412 .

I also think that if you tossed 13

volts at this and used 2 killer fans to kool the gear you could do freq 450 .

In this sense the s-5 is better then the sp20.

My problems are the s-5 does not fit as well as the sp20 in my garage setup. I will run my s-5 at freq 300 . I will use 2 delta fans and 5.5 volts per fan.
If the s-5 had the s-3 case I would have grabbed 5 to 10 or them.

I am going to try to run the deltas with 4 pins tomorrow . Hook them direct to the s-5 . See if I get the pwm to work.

'The right to privacy matters'

last test will be how to have the miner quiet with the delta's

I will clock to freq 300 vs freq 393

I would think hash will drop to about 1000gh vs 1290-1300gh--------------------------getting 950gh

I will set fans to 8 volts hoping for 50db and temps under 60c------------------------------58db temps are 54 c in a 73 f room

I went to 7 volts temps are solid 56/54 in a 73f room sound dropped to 56db hashing at 978 gh not quiet enough to run in a room and watch a tv show. but close.

Will drop to 5 volts as many atx psu's will allow for a 5 volt power supply.

at 5 volts db is under 48 47.7 db noise is not an issue. but at freq 300 it is just over 60c in a 73f room.

Have to say if you have a cooler room then 73 f two of these deltas in a push pull work . you get a quiet miner quieter then the sp20 at 1000gh.

I will post a screen shot later . my guess is 2 deltas at 6 volts or 2 deltas at 5.5 volts would be better then 2 at 5 volts unless your room is cold.

'The right to privacy matters'

now you do not need that adjustable psu to do fan control

this can do about 6-8 deltas

use 2 of these one pos one neg

and a piece of wood for mounting

will control fans pretty good may be just a bit too fast.

now to power the antminer. I used an evga 1300 g2----on the top left also note room temps is 73f

but I wanted a decent test bed for the deltas
so here is the power supply and the power distribution

this is a jetstream power supply makes for an amazing fan controller

power distribution and the volts to the fan

stock long screw holds the grill

meter reads around 60 to 62 and you get pretty fast hashing at freq 393

next photo I got some screws from lowes

you can get the short ones

and not use the long ones

if you do this use two short and two stock screws per fan. put on grills my thumb still hurts!!!

okay I finally got an s-5 after selling the demo to a friend.

I am using 2 delta fans push pull db = 61

Stock db = 75

I have a seperate psu that can go from 3 volts to 15 volts I am sending 9.22 volts to the 2 delta's.

and here are the current readings on the s-5.

nice overclock at freq 393 runs cool .

I can crank the fans up to 10 volts but at 9.22 volts they do the job and the noise is okay. loud but not crazy nasty loud.

44 hw's out of more then 1,000,000 are nothing.

>snip image<

Great.
Probably the best hash with OK noise.

yeah got lots of photo's here is the first one

I give my blood for Bitcointalk. I cut the fuck out of my thumb putting in the deltas. the fans have really solid blades be careful!!!

man i love these S 5 just got my fist one today with two more on the way . the fans are not that bad but yea I can see were 6 or more going at once would drive me up a wall i just sold all but two Zeus miners the noise levels form them are as bad as 4 of these to one of those,it forced me to sell, they use way to much power and i get nothing in return . at least with these i can lower the noise to were 7 or so in one room won't be bad and use way less power and get more maybe not a real good RoI but some thing worth the effect to me . so all in all the S 5 are really really nice for me so far expect the sound over time will get to me so I'll fix it or am as we speak and gonna get 7 to 8 , in time.

So I think I found a solution to the high pitch whine of the stock fans. We all know the guide vanes are what's causing the pitch. I received a fan with a broken blade on my my batch 1 S5's and Bitmain was kind enough to ship me a new one. I decided to do a little experiment today to see if reducing the number of vanes would change the pitch, which for my ears (healthy 35 year old) now sounds more like a S3.

You notice on the vane there is a thicker part on the outer edge, I took some wire cutters and cut every other vane right where the thin part of the vane meets the thicker part (careful to line up the fan blades so you don't accidentally cut one). I then used my thumb and as close to center as possible I just pushed down on the cut vane and it popped right off. Note that the power wires run down one vane so you probably will want to start there and you'll still end up with an odd number of cuts. Here's a picture and for those brave enough to try it, let us know your results. My temps are exactly the same and I do use a high cfm pull fans as well. Still experimenting with those, so far the Silverstone Tek 140mm x 38mm Fan seems to be giving me the lowest temps but these S5's seem to run in all different temperature ranges so it's all subjective.

>snip image<

That has been my thought/plan if and when (a big if and when) I get S5s except I would be leaving only 3 or 4 vanes and Dremel the rest of them out "clean". If that will not be satisfactory, there's always the Delta fan option. I'm glad to know that it did make a difference.

My only suggestion would be to remove and test. The vanes do make a big difference in channeling the air down the center and across the heat sinks. I have higher CFM and higher pressure fans that should in theory cool the S5 down better but without those vanes to center the air they aren't as efficient and my temps get dangerously high. Unfortunately we're stuck with the stock fans or Delta's, for us home miners that don't have climate control.

No, we are not (see highlighted). I use Noctua 3000-great for 325mhz/1070Gh and much much less noise or Noctua/Scythe combo-OK for 1100 Gh at one step up from 325 (331 something?).

that looks like it could work.

As a completely different question coins are now 223 usd.

next diff may drop back under 39.

It looks more and more like s-5's or sp20s are a home miners only chance .

I get an s-5 tommorrow I will post shots of it with modded delta fans. this will bring me up to 8 sp20's and 1 s-5

I may buy another s-5 but with this drop in coins it is very tough to do.

Hi,

Whats happening if you use only 2 pcie power connectors?

You're cables and PCI-e connector will melt! Max 250 watt per cable, less if you use flatcables. With the S3 yes, with the S5 NO!!!

I have two S5 coming this week my question is i can use two of these on each S5 I hate noise I'm 58 . I have two of these fans right now on one of my S1 I'm replacing with S5 .I'll either junk the S1's save the heat sinks for some thing later on or sell them super cheap on Ebay.

http://www.amazon.com/gp/product/B00FKNAG7Y/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

I have two deltas similar to the ones you have on an S5 that runs very quite. There is a link to a video here it has 15 seconds of SP20s and 15 seconds of the S5. Not a very scientific approach but a quick and dirty comparison: https://bitcointalk.org/index.php?topic=902305.1240. I like both unit types as they both serve me well.

TY Man I was little worried about the noise i would have to buy some kind of cabinet to put them in or sound proof a cover some how .
