Can you post a picture of how did you connect fan wires to the Jabber board?

There's no secret sauce to it - the fans are 12v so I just made a PCIe adapter to connect it. Just positive to positive, negative to negative - the only trick is whether or not the fan will be full speed without a PWM signal (most work like this), or use a 3 pin fan.

My first rev I hard-wired it, but I had a fan die on one of them and it was a huge PIA, so I switched to making an adapter - and finally added the thermal PWM board.

I'd be interested in a couple of these when the kit is ready.

I did get very good results with the sound proofing here are results with the avalon 6's and the s-7

and sound meter readings

on the den/home theater couch with garage door open--- 39.7db

about 46.8 a few feet from garage door

at the garage door 52.4

in the garage 59.7 pointed towards the intake spot

the outflow spot = 60.9

lastly right at the intake of the 2880 watt psu 71.8 notice sound proofing i will post the sound proofing technique later today.

I did it for one customer, and never got a complaint since he got it in april.

Anyway, for those interested, Molex part numbers to connect a 4 wires PWM fan in place of the fan pack are as follow:
Microfit 3.0 receptacle (4 contacts): 0430250400
Microfit 3.0 Female crimp terminals: 0430300001 (or 0430300007 if you don't want to order a full reel)

I'll try to get back the pinout from a disassembled fan pack I have laying somewhere or from the pictures I sent to my customer.

Cool - I ordered those up from Digikey... You wouldn't happen to know the part number for a male KK 100 connection, something that a 4-pin PWM fan could connect to? Like these:

To save some time and work, you can use the original connectors 4 pins microfit, I'll dig the reference. I still have a handful of connectors and crimp pins laying somewhere.
The original fans are 4 pins, and temperature controlled.

Yeah, I had considered that but wasn't sure how it would handle the different fan charactistics (ie; 1 fan instead of 3, 5000rpm instead of 12000rpm, etc). If you could post a link to the datasheet on it, that would be great and I'd give it a shot, converting over those connectors on the board would be trivial, as I pull them out anyway.

If that PSU was having issues, it's a lemon. I think Phil was running on 120V back then too. 240V is easier on the PSUs, I hope you'll be using 240V with 6 S7s?

EVGA says you can pull 1300W DC from them, IE ~1450W at the wall for 10 years. That's good enough for me! Worse case they replace the PSU for free.

I've got them running on 208v actually. I've got a 100amp subpanel just for mining.

I'm pretty close to my solution for making a quieter version of the 2880w... It works really well so far, here's a picture of my almost-complete version:

http://www.analogx.com/images/2880w/DSCF3428s.jpg

I replace the front fans with a 120mm server-class fan blowing directly down - I block the front of the device to force all the airflow out the back. Above the hottest part of the PSU I have a thermal PWM fan controller, so it varies the speed of the fan based on the units temperature, and seems to do a pretty good job. How loud it is depends on a couple factors, such as ambient temps and which 120mm fan you use - but it is MUCH quieter than the stock option, much closer to a slightly above-normal ATX PSU (because the fan is a much higher airflow and SP fan than a normal ATX PSU would use).

I've changed the latest design to use primarily zip-ties to hold everything together - works super well, is inexpensive, and non-conductive.

That's good to know as i was getting nervous after reading what Phil had to say. Looking at graphs, efficiency is decreasing at least 5% at or above 90% load.
Yes, I was running at 110/120V, but I send them all out to hosting with sidehack-posted review in Hosting service thread.
I like his arrangements and service.

Aside from the decreasing efficiency which for ATX supplies actually largely is from the fans running near/at full speed and taking more power to do it, with ANYTHING dealing with power be it plug/circuit ratings and including PSU ratings always follow the 80% rule. For the feeders it keeps plugs/cords/wiring behind walls at safe temps when under a constant near-max load - which miners present - for the PSU's you need that margin to handle the random (hopefully) short-term events all powerlines have.

For example of pushing ratings just talk to Bitmain and their experience with early s2 PSU's.... But as long as you have spares to cover ya while EVGA ships a replacement then your call. Und ja, as has been often said, any PSU is much happier on a 208-240v line because of the lower currents on the AC-line side of the power conversion.

You sure you guys can't put a resistor between some of the pins to regulate the fan speed?

If the resistor is put in the +12v line feeding the fan, sure it will work as a brute-force way to do it. Question is it a 3 or 4 wire fan? With either 3 or 4 wire it will be reporting it's speed, 4-wire gives it built-in PWM control.

With 4-wire most often no signal = fan ON (for safety and convenient way to let fan go full speed if wire 4 is open) and +5v = Fan min speed. Play with the signal duty cycle to set the speed between it's min and max speed.. Dunna know if the PSU's fan circuit does anything re: monitoring the speed except for maybe checking for a stalled fan.

That's what I'm looking for too. Maybe I'll end up using the 2000W PSU and be very careful about picking quiet fans? Not sure.

I'd still love to hear how to add the two fans to the top of the 2880w PSU I have right now. That might solve the problem entirely.

Keep in mind it's still a server PSU so it will not be quiet. But yes it's more quiet then that beast of 2880w server PSU.

Most server environments noise is not a big deal... so most server PSU's quiet was not a concern specifically on higher wattage ones.

I love those PSUs, I'm 20 of them. There's 2 models, RA and NA. NA sounds like a cat in a bag being kicked down the street, RA is much less whiny. Inaudible at 50% load or less, while NA is still loud at 20%.

I use 2 RAs with load sharing mode enabled in my house to power a 5 cube Titan space heater.

Yeah, i'd like some nice enclosure but indeed at 50% load, they are quiet enough.

I went crazy and put ton of electric tape around the ground and 12V, just in case my cat decide to go there. And then i added a milk crate over it. It makes me a bit fidgety, i'd rather have ATX. But hey for now they work. Later on i might sell them in Canada.

I'm sure it's possible, but I wouldn't want to risk them overheating. Modding 120MM deltas on top of them is probably the best way to go.

Definitively do it this way.

Even my Platinum server PSU heat up with their ear-rape fan at full blast. Modding them to use big fans would make then cooler and much more quiet.

What platinum server PSU are you referring to? LOL at ear rape fan.

These;
http://www.digikey.com/product-detail/en/PFE1100-12-054RA/PFE1100-12-054RA-ND/3535541

Got mine from Quakefiend, they're pretty small/thin so modding them would be a pain. So to save my ear, i just put 50% load on them. At 70%+ its like a car that need to replace its breaks. The noise become ultra high pitch.

At 50% load they're better than S5 fans at 2600 RPM

Hi all,

I just hooked up three different IBM Bladecenter H 2880W PSU's to my brand new S7's, and boy the fans on these PSU's are incredibly loud! These PSU's have a high pitched sorta whistle sound, almost kinda like the whistle you hear on a turbo. These PSU's have a pitch more noticeable than the actual miners in the room.

My question is, is there any way to make these fans quieter at all? Or a replacement for the stock fans that are quieter? Otherwise, do I have any other options? I ideally wanted to run platinum PSU's to these miners, so if there is no solution, is there a recommended replacement that you guys suggest?

Any help is greatly appreciated, thanks.

Server PSU's are not known for being quiet. I doubt you are able to make it what you consider "quiet". If going for less noise I traditionally would send someone twords ATX vs server psu. I don't know that I have seen much as far as making them quiet. If someone can think of one please post, I could not find quickly.

I think they are just loud PSU's at end of day. They are great for their price and amount of power, not for quietness.

But the problem with this is the 10 PCIE cables the S7 want's. That get's most ATX psu's where they are not to good for the job.

I think that EVGA 1300 with two extra PCIe extenders is OK for S7 batches 2, 4 and 6.
For batch 1 could be OK, depending on your optimal mhz setting and without overclocking
For batch 3, 5, 7 (and especially 7), EVGA is probably insufficient.
Batch 3,5 were close to borderline w/o overclocking, but probably insufficient if overclocking to 625.
batch 7 jumped to 1345w at the wall on EVGA 1300 from the getgo without any oveclock, so 1600 is probably needed, but they are expensive.
Batch 6 is OK even when overclocked to 650-4.3Th at 1160W at the wall.
batch 8-also probably needs Bitmain's PSU or EVGA 1600 (or 2880W IBM for two, of course).

EVGA G2 1300w at 1345w at the wall is just fine, that is only 1224W and they can feed 100% of their rated load 24/7 for their whole MSRP and they are garanteed 10 years, so...

Anyways TLDR; that is 94% load, no problem for a EVGA G2.

Phil was saying on some other thread that he was running EVGA 1300 at 1320W at the wall and it was OK short term, but became weird (probably unstable or "spiky') after 1-2 month of constant load.
I would like (if possible) to set up PSU and keep it going for the duration.

I don't have that problem on any of my miners and they're all running EVGA G2's. If the PSU spike after so little time, then its defective and should be RMA'd.

If you dont already have a 1300, then you can get the more expensive 1600W if you're looking for peace of mind.

Would the 1300 run my batch 7 miners tho? I've read the actual usage can sometimes spike up to 1400w on batch 7

1400 watts at the wall *0.9 (efficiency) = 1260 watts fed to the miner. You won't have any headroom for overclocking further but its "ok". I run my EVGA G2 1000 at 1000-1050w at the wall because i wish to be a tiny bit conservative, but if you already have the 1300, i'd go with that. Personally i like to keep my At the wall at up to what the thing is rated, for maximizing the lifetime of the PSU.

The downside is at close to 100% load you're not at 92% efficiency anymore. If you dont have a 1300 yet, you could look into something higher.

If you have more concerns about running the miner at 95% load, check the Johnyguru reviews.

I think that EVGA 1300 with two extra PCIe extenders is OK for S7 batches 2, 4 and 6.
For batch 1 could be OK, depending on your optimal mhz setting and without overclocking
For batch 3, 5, 7 (and especially 7), EVGA is probably insufficient.
Batch 3,5 were close to borderline w/o overclocking, but probably insufficient if overclocking to 625.
batch 7 jumped to 1345w at the wall on EVGA 1300 from the getgo without any oveclock, so 1600 is probably needed, but they are expensive.
Batch 6 is OK even when overclocked to 650-4.3Th at 1160W at the wall.
batch 8-also probably needs Bitmain's PSU or EVGA 1600 (or 2880W IBM for two, of course).

EVGA G2 1300w at 1345w at the wall is just fine, that is only 1224W and they can feed 100% of their rated load 24/7 for their whole MSRP and they are garanteed 10 years, so...

Anyways TLDR; that is 94% load, no problem for a EVGA G2.

'The right to privacy matters'

okay I have a titanium evga 1600
and I am soon to have the 4000 watt setup from finksy/j4bberwock
plus the 2880 watt setup
plus the 1500 watt adjustable meanwell psu
plus the seasonic 1200 watt psu

MY goal is to do a huge thread on all 3 plus the seasonic 1200watt platinum

and lastly the meanwell 1500 watt 9.6 to 13 volt psu.

having 240 volt in house I am pretty certain the winner will be the 4000 watt setup

here is the evga 1600 tit running a batch 2 . this s-7 is very nice I am getting really good numbers

here is a pair of avalon 6's the blue lined one is using the meanwell 1500 watt set at 12.2 volts it drops to 12.1
the unlined one is using a seasonic 1200 watt plat with custom 16 gauge cables it drops to 11.9 watts
the avalon with the seasonic seems to hash higher but it is first in the chain to the rasp pi

evga 1600w is your best bet. 10 year warranty too. quality cables, quality power cable. all kinds of voltage protection. Its not silent - but there is a reason I refuse to get server psu's for my garage....the high pitch noise is too much. Sure If you have multiple s7 then getting atx will be expensive, but if you run one, invest in a 1600w, you can re-use it for literally anything after and its good quality.

Yeah that would be too spendy for me. I have 3 S7's currently, and another 3 coming in (batch Cool

likely by Friday. Hence, 6 EVGA PSU's blow my budget out of the water.

I've seen the Delta 2000W PSU without the breakout board for $30 on ebay (and the breakout board is $45 I believe), so since I already have all of the PCIe cables I need, all I'd need is more C19/C20 cords, and some fans. I don't know how expensive fans are, but My guess is that I can probably get everything I need for around $100 each PSU.

OR, I can add those additional fans to the top like Jabber suggested. Jabber, when you have a moment, could you please send me those schematics and how they work? Thanks!

Cheese and Rice, the EVGA 1600 is over $300! That's insanely expensive, considering one of my IBM Units power two S7's, and including the awesome Jabberwock breakout board and 20 PCIe cables per PSU, I bought them for about $260 before shipping and C20 cable, each.

Jabber, tell me more about how this fan mod works, and how to go about doing it.

Also, you said that the 2000W HP unit is quieter. If I use one of those, I'd likely have to use 1 per S7, so how much would one of those set me back overall?

Thanks guys, I appreciate the help

Yep, used server PSUs beat ATX PSUs in every way. The 2000W is an IBM, not HP. DPS-2000BB made by Delta, to be precise. 1 PSU powers only 1 S7, but combining 2 PSUs into a 4000W unit lets you power 3 S7s.

It might be cheese and rice. But the noise HUGE difference between the two. If you want 10 PCIe cables it comes at a very high premium at ATX PSU's. It just is how it is. Think about it how many regular computers do you know using 10 PCIe? That is reason so few ATX even exist for it.

So you can stick with your current PSU's which is not a bad option. But you will have loud PSU's that is just how it is.

I have the 1600w Titanium. It's seriously an incredible PSU, I measured 96% efficiency at 50% load and 94.5% at 100% load. The fan doesn't even spin until somewhere around 1000w load. I no longer need it if anyone wants to get their hands on it for a great price vs retail.

Hi all,

I just hooked up three different IBM Bladecenter H 2880W PSU's to my brand new S7's, and boy the fans on these PSU's are incredibly loud! These PSU's have a high pitched sorta whistle sound, almost kinda like the whistle you hear on a turbo. These PSU's have a pitch more noticeable than the actual miners in the room.

My question is, is there any way to make these fans quieter at all? Or a replacement for the stock fans that are quieter? Otherwise, do I have any other options? I ideally wanted to run platinum PSU's to these miners, so if there is no solution, is there a recommended replacement that you guys suggest?

Any help is greatly appreciated, thanks.

Server PSU's are not known for being quiet. I doubt you are able to make it what you consider "quiet". If going for less noise I traditionally would send someone twords ATX vs server psu. I don't know that I have seen much as far as making them quiet. If someone can think of one please post, I could not find quickly.

I think they are just loud PSU's at end of day. They are great for their price and amount of power, not for quietness.

But the problem with this is the 10 PCIE cables the S7 want's. That get's most ATX psu's where they are not to good for the job.

Do you know of any ATX PSU's that are gold or platinum rated, that have slots for the 10 PCIe cables? Or a quieter sever grade PSU (I hear of people using Dell PSU's and other PSU's that run about 2000w max).

Or maybe Jabberwack knows of a quieter sever PSU with one of his breakout boards?

EVGA 1600 has 9 PCIe ports, you can easily add a splitter to power S7 controller. They come in Gold, Platinum and Titanium, they are whisper quiet but expensive.

actually, EVGA 1600 has 10 cords (one is longer) with 14 connectors already there.
see here (scroll to the bottom of the page):
http://www.newegg.com/Product/Product.aspx?Item=N82E16817438033

You are right, forgot about the dual PCIe connectors. Also Titanium ones are as good as or better than the server PSUs efficiency wise.

The 2880w PSU can be modded with holes in the top cover to fit 120mm fans. I believe MarkAZ did something like that.
I have the reference and the pinout for the original fan plugs somewhere from when I did the mod for someone locally.

The DPS2000BB can be much quieter (you can choose the fans you use since you need to add external fans). Mounting the fans with my single and dual DPS2000BB sideplates for the 4K breakout board is a little bit easier than without.

Ear plugs. Or mod the PSU by adding 2 powerful 120mm fans to the top of it.

I stopped using my 3 PSUs, just too damn loud. I had them in a detached garage and they were still too loud, could hear them in the house and down the road 100 feet away easily.
