ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH

[chiguireitor]

How many AMP breaker do I need to power 3 S5s running on one pair of outlets? 2 in 1 and 1 in the other. 2 are running on 15 AMP breaker right now but third coming today.

I am running at Freq 400 right now but will be dialing back to default because it is starting to get warmer here.

I have a 3 X 15 AMP breaker powering a baseboard heater in my garage and can bypass that for rigs if need be.

120 Volts here.

I have three on a 20 amps breaker at home.

I thought I had a 15 AMP but as it turns out I have a 30 AMP and can confirm that 3 S5s will run on this. I am not overclocking anymore. All at 350 Frequency. Purring along. New 20 AMP breaker goes in today so I can buy more

Just be sure that the cabling is up to par with the amps you're asking the circuit. I had some cables burst on me the other day with just a few miners on it because the wall wiring was shit.

I'm starting to think these miners should have been what the C1's were.

They run with that open-built extremely loud full speed fan and still are over 50C.

Even the SP20's at Fan speed 50 are more quiet than these things.

I will use a new cheaper mod tonight-we'll see if it works. ~$20-24/miner.
Lowes in my area is completely out of pan M4-0.7 35-45mm screws. had to buy hex.
I surmise that S5 modders scooped them all up, LOL.

i think im going to probably pick a couple of these up.

they seem to flow alot of air and are a tad quieter..
probably not as quiet as the fans on the s3, but as long as they dont whine im ok.

It's my opinion that a fan with lower CFM than 4,000 RPM's should not be used on these rigs.  They do run very warm with one fan.  I presently have temperatures of 62 C on Chain #1 and 62 C on Chain #2 with the single fan at 3,840 RPM.  The Ambient temperature is 74 F.  The true purpose of getting a second fan should be for proper cooling of the unit.  One should not be concerned as much about the noise as they should about proper cooling of the rig during the hotter months of the year.

Yes, a fan with 4,000+ RPM's will cost more but it's worth it in my opinion.  Proper cooling and longevity of the rig is more important than the noise level to me.  My opinion; that's all.  Please don't take it personal.

True, cooling is critical, and so, if need be, underclock is necessary.  Fan noise is major to me since the miners share my living space!  Adding an exhaust fan makes it easier for the intake fan to do its job, doesn't have to be noisier than the single.  Very interested to see how the Silverstone works out on the exhaust (two S3 fans on an S5 are much louder than one, though still easily quieter than S5 stock).

i was thinking about putting that fan in the back and leaving the stock fan in the front.

[opentoe]

The S5 are running great and so I've moved them to CGminer 4.90 and 312.5MHz.  The highest reported temp is 57C with an S3 push fan and no pull (ambient ~72F, fan rpm 3240).  Am intending to try the FHP141 as a pull.

My final two S5 shipped Friday and would have arrived Monday, but somehow, the UPS driver screwed up the delivery and a different driver completed Tuesday -- bummer on the whole day delay, lost some good WestHash payout !!!

Have received two each by USPS EMS, Fedex, UPS, and all would have been "two day" delivery (excluding Sunday and the UPS SNAFU), lowest shipping cost was EMS via DHgate back in January.  The latest two (with S3 push fans) are setup side by side on the floor of my coolest room running 312.5MHz and temps 47/42 and 43/40 (top temp was 59 Vs 52 at 350MHz over a 2-1/2 hr check out). That first consistently runs by far the highest temp and fan speed of my three pair and makes me consider the heat sink paste mod described earlier** (currently 2760 Vs 2160 rpm) -- it also had pre-damaged Phillips head screws by whatever gorilla installed and warped the plastic side panels (since loosened).  Am expecting to give Silverstone FHP141 pull fans a try this coming weekend.

Thanks again Bitmain for the timely ordering assistance (Janet/Tim) and quick turnaround of the order -- here's looking forward to learning about the next generation!

The location matters too. I don't care how loud mine are because they are in my garage and can not be heard in the house. Now if it was in my house I would have to reconsider my options.

The only fans I've seen cool an S5 in a push pull setup were the Noctua Industrial 3000's. While temps went to 59-63c that's well within spec of the unit.  2 140mm fans are too large. Won't be able to funnel all that air into the miner.

[pekatete]

Just three fans available and mentioned, with the cheapest being the thermalright. I have this running on my S5 without PWM in a pull configuration with a stock S3 fan on PWM in a push configuration and my temps struggle to breach the 52 mark during the day (it is winter turned spring ... just), having skirted the mid to late 60's with just the stock S3 in push full pelt!. I can say noise is definitely less than a stock S3 fan running without PWM.
PS. though I run the thermalright without PWM, the maximum the S5 has reported it running is 2400 (despite it being rated at 2500).

Fan	CFM	Noise	RPM	Depth (mm)
Thermalright	130	45	2500	26.5
Noctua	109.8	43.5	3000	25
Silverstone	171	43.5	2000	38.5

Saying that, I'd swear by these HP Proliant ML530 130mm Fan TA500DC. I have a couple of these running on overclocked S3's in a pull configuration with voltage limited to approx 7v thus less noise. I'll probably be running one (if not both) of my next S5's on these though ....

I was in Microcenter the other day and they had a Delta Fan Delta AFB1212SHE for $20.  Couldn't pass it up since I had one on the truck.  I can't tell the specs of it.  I see several different models on the website: 

http://1stpccorp.com/fan_delta_120mm.htm

I do know it is 1.6A rating, but that's about it.  But like the specs I see.  It also has a 4 pin connector. 

Damn, i missed UPS.  Off to the service center i go.

What is the fan model on the S3. Have to remember there are lots of people out here that do not own S3's and do not have those fans. Also if you buy a 2000 rpm fan it will probably run at max speed all the time. So if there is a 3000 rpm fan and a 2000 rpm fan each rated at 43dB the 3000 rpm model will be more quiet because it has a little more room to keep temps in check. You also really can't go above 120mm in size. If you do the fan will be larger than the whole miner itself and be just wasting air. For this one, ya gotta spend the cash on the Noctua's since in my opinion are the only ones that can keep up in this environment and keep temps in check. Soon though I'll have all my S5's in one room after I run a few electrical lines with my dad over the weekend. Then coupled with a window air conditioner on a high setting so it is not on all the time should be just fine for temps and good for the ears.

Delta's are usually screamers. I think I saw the same fan at MicroCenter. It was the only Delta 38mm model there and it even said on the package you may need ear protection when in use for long periods of time.

Westhash still paying pretty good? What's the price you use in the password line?

NiceHash/WestHash payout depends on their hash sales -- generally in a state of flux and often less good than mining BTC directly, but happily often not.  My payout threshold depends on current BTC Difficulty and so I change it every two weeks.  My current value is "p=.0109".  It'll change again by Monday coming.

[dmwardjr]

I have purchased eight [8] of these fans in total from the same seller on Amazon:  Delta Electronics PFC1212DE 120x120x38mm Cooling Fan, 252.85 CFM, 5500 RPM, 66.5 dBA, 4.8 Amp, PWM Connector (4-pin).  It is $27.00 with free shipping.  You do not have to be a Prime member to get free shipping on this one.  The seller is selling this through Amazon.  I'm sure they have already added shipping to the price.  It's worth it to me to pay $7.00 more for a great quality fan with lots of CFM.  This thing is a beast!

I use this fan as a replacement on my S4's and S5's.  I plan to replace the stock fans on the SP20's with this fan as well after the warranty period is over.  This is what you need when replacing fans for the SP20:

I was going to give it a try, but doesn't going back and forth on your primary pool reduce your return? I also don't have the time to keep checking prices and values, nor where to look to know what number to enter in. More reading to do. I've been doing a lot of screening the forums so I missed a lot on the Westhash stuff.

Depends on your pool.  If you are on Slush, it only takes about an hour to get ramped back up to full payment; or at least very close to full payment.

What is the fan model on the S3. Have to remember there are lots of people out here that do not own S3's and do not have those fans.

No idea, though I have seen it mentioned in this thread (if not forum).

Also if you buy a 2000 rpm fan it will probably run at max speed all the time. So if there is a 3000 rpm fan and a 2000 rpm fan each rated at 43dB the 3000 rpm model will be more quiet because it has a little more room to keep temps in check.

You'd be wrong in making that assumption. The Noctua (3000 rpm) may have to run at full pelt as opposed to the Silverstone (2000 rpm) because the latter has higher CFM, i.e moves more air faster, thus it will move more air at lower rpm's than the Noctua at full pelt.

You also really can't go above 120mm in size. If you do the fan will be larger than the whole miner itself and be just wasting air.

I am not completely sold on the wasting air argument, suffice to say the thermalright is a 140mm fan with 120mm mounting and it works just fine for me mounted at the front in a pull configuration. Note that you may need to trim it if you want to deploy in a push configuration if you have a chunky ethernet cable.

Just a note about my observation on this, if you mount one of the suggested fans in a pull configuration and run them at full pelt (because they are less noisy), then you can run even the stock S5 fan in a push configuration on PWM. That way, the S5 temps will be low and the S5 will lower the RPM's on the stock / push fan. I was surprised after installing the thermalright that the S5 was lowering its RPM so I disconnected the blue wire (disabled PWM) on it and now the stock S3's whine (on PWM) in push is barely audible over the swoosh of the thermalright.

I was reading Organofcorti's blog about how Ghash.io had a lower return compared to others, but I did leave a response asking if that was picked just from a date range or not. At any given time one pool or another could look really good, and look really bad. I don't see how Ghash.io can even implement skimming or stealing your money. This is what I have been told. I mean they have huge data centers of their own, not sure why they would even bother doing anything like that. Unless my perspective is off a little. I don't know.

My rigs are actually inside my house.  However, they are located downstairs.  I will not install grilles in the other doors until more rigs are added to justify installing additional grilles in the doors:



Don't be fooled... The fan is not held up by zip ties [lol].  The next picture shows the clips holding it in place.  The entire fan is resting inside the circle I cut in the wood with a jig saw.  The clips are holding the fan in place while it rests on the wood.  I found there was no need to screw a bolt through the black hanger into the joist above.  The fan rests perfectly on the wood while it is pushed through to the outside approximately 6 inches to where the handle rests against the wood.  So I decided to attach the handle to the wood to hold the fan in place.

The reason I have more wood to the left of the fan is to allow space to mount my power outlets, etc.  I will mount the outlets in place later.  I was tired last night!





All rigs not on the rack yet. [Five S4's; two S3's and 15 SP20's on the rack in the new closet] More rigs still had to be moved in.  You see them in the background:



All rigs but S5's on the rack in this pick [Don't mind the black paint on the wall]:
