I use case fans out of Dell Precision 380/390's etc you have to move the pins around in the connector to match how bitmain wants them. they are the same fan bitmain uses. blue/white/red/black.   black being the innermost pin blue the outter. or you can get corsair power supply fans but none of those match the CFM of these fans.

dmwardjr,
You really need to read the latest posts in the S4 thread as the PSU's are crap and are catching on fire. Would not put into my house at this point. Wouldn't be surprised if bitmain pulls them for now they know they have some serious problems that could potentially hurt someone.

Very sorry.  I don't know why I had it up again.

Nice pix indeed - but we really don't need to see them over and over again.  Please, guys - edit your replies before hitting Post.

One of my S3's I just got in has a fan that does not work.  It is an S3, not S3+.  They said it was "new" but it's obviously not!

Anyone know of a good fan to replace it with?

I will look it up while someone might possibly reply.

EDIT:  I still haven't found something yet as to replacing the fan with another.  Seems like I remember reading where someone replaced their fan with one that spun at faster RPM's and it cooled it down even better than the factory fans.

Can someone help?

NO, 10/3 ...  NOT 12/2.

WE MUST USE 10 gauge (10/3) for THAT outlet.  Otherwise, it is insufficient wire for a 30 AMP outlet.  It can get too hot and burn the house down if the breaker doesn't trip first.  

I HAD TO MAKE SURE you understood in case you do the same so YOU do not burn your house down.  

PLEASE don't think I'm shouting with the capital letters.  I'm only using caps for emphasis!!!

10/3 or 10/2 is rated for 30 amps.  12/2 or 12/3 is rated for 20 amps.  14/2 or 14/3 is rated for 15 amps.

RUN 10/3 wire [Rated at 30 AMPS] to a 30 AMP OUTLET [NEMA L-14-30-R (circular/4 prong)].  IT MUST BE NEMA L-14-30-R/CIRCULAR.  OTHERWISE, IT WILL NOT ALLOW THE NEXT THING I MENTION TO PLUG INTO IT.

I see, that makes since - 2800watts/24 amps is good for 10guage wire with 30amp breaker. (Corrected)
Sorry I didn't read back, I was just fascinated by the pics.

You wil see my explanation in the previous reply to this one.

I will end up with 16 S3's and 8 S4's.

The four 30 AMP circuits will have two S4's on each circuit.

The more I think about it... The new Bitmain Antminer S4 is a good choice for the price.  Especially, since it includes a built in PSU [Gold Rated].  My ONLY concern is IF the built in PSU goes down, can it be EASILY hooked up to an external 1600 Watt PSU?

Is there anyone on this forum who has an S4 [Who may have opened it up] that could tell me if it can easily be hooked up to an external PSU in the event the internal PSU goes down?

It would take 4 Antminer S3's to make 1 S4.  THEN you have to buy 2 PSU's to power the 4 S3's.  Yet, you are still short approximately 200 GH/s from the 2 TH/s hashing power of the S4.

ALSO, 4 Antminer S3's with two Corsair AX860's [PLATINUM] would be a combined total of 1440 watts at the wall.  You get 200 GH/s more hashing power with the S4 and 1380 Watts at the wall.  60 Watts LESS POWER WHILE GAINING 200 GH's more hashing power.  THAT IS EXTREMELY ATTRACTIVE!

I'm tempted to buy 2 S4's instead of 10 S3's.  VERY TEMPTED!!!!

Yes, the S4 requires 30 AMP outlets with a 20 AMP splitter cord to make it possible to hook up 2 S4's on a 30 AMP circuit.  I've already addressed this earlier on page 940 of THIS forum.

Agreed!!!

I still believe BTC will be at least $510.00 by midnight on Thanksgiving.  I made a 0.1 BTC bet on it.  Making preparations!!!

Thanks!!!  I'm looking forward to it's completion.  

Sounds like Alice and Wonderland around here.

lol

I've been a little busy today.

I bought two 10 feet sticks of electrical 1 1/2" PVC pipe; two 1 1/2" elbows; etc...

I measured the length I would need for 12/2 w/ground [Ended up needing 17 feet].  So, I cut 17 feet eight 8 times for 8 20 AMP circuits.  I cut the PVC to 78 inches (6.5 feet) and glued them to the elbows.  Then I ran 4 of the 17 feet runs into each PVC w/elbow setup out in the driveway.




Then I cut the holes at 13 inches from the floor to the bottom of the elbow [going through into a small closet]; mounted the 2 PVC setups with straps; ran the 8 circuits into bushings going into the top of the main breaker panel.  

Tomorrow, I will wire strip the wiring and connect them to breakers to install in the panel.  I will be putting four (4) 30 AMP circuits [10/3 NH-B wiring/2 in each 1 1/2" PVC set up you see installed in this pic]. I will simply fish them down from the top; 2 in each pipe with the 4 circuits that are already in each pipe.  Those will be fished through when the S4's arrive.  

I'll show you a picture of the closet when I finish putting in the receptacles and mounting wired shelfs [not wood; need the heat to go through the wire shelves up to the ventilation near the ceiling where I will have exhaust fans going to outside].




This is the small closet downstairs.  I still need to put grout down.  The tile is new.  The 8 new 20 AMP circuits will be in this closet.  I'm putting together 8 receptacles (outlets) to mount to a piece of wood; which will then be screwed down [covering the rectangular hole you see now.  I will paint the wood white to match the base molding that I will also paint white after I grout the tile.






I have a damn good idea for setting up the farm in the closet with an air conditioner for servers and ventilation to the outside.  The air conditioner is 12,000 BTU's.  Good enough for 500 square feet.  The closet is only 30 square feet.  So, that ought to be PLENTY of cool air for that closet with 16 S3's and 8 S4's (23.7 Th/s).

.1505884 x 40% should = .06023536 not even there math is right and I would of even taken replaced time not just the btc however no one wanted to compensate me for the lost 10 hours of hashing on Slush's as previously stated if the mine owner Muncher had a power outage something beyond his control I would be more forgiving but a scheduled Sunday pick up by fed-ex to move data centers come the F on

Here is MUNCHER's email reply 8 hours after offline and 3 hours after i contacted him

"Hi Wasikidding!

The owner of rig #7867 ⚒ [Muncher´s Mine] Sp 30 4.5TH [Datacenter Hosting] that you are renting has sent you a message!

I am very sorry for the caused inconveniance.
It seems like the units are currently being transferred to another datacenter with lower ambient temperature.
I wasn´t aware of the exact time this would happen and therefore couldn´t make it not available for renting beforehand.
I can either offer you to extend the mining duration, or you can write a ticket and get a partial refund, equal to the amount of lost mining time.

You can reply to this message by going to the rental message page at http://www.betarigs.com/rig/7867/job/165986/messages and also, if the rental is still active, at the rig page at http://www.betarigs.com/rig/7867

Cheers! Mux from Betarigs"

So I assume Muncher works for Betarigs therefore it's ok to screw people luv line 3 I wasn't aware of the time this was gonna happen so i couldnt take offline

here is his email asking how i lost the 10 hours of hashing and telling me how fed-ex takes 48 hours to deliver and setup mind you this is Sunday

"Hi Wasikidding!

The owner of rig #7850 ⚒ [Muncher´s Mine] Sp 30 4.5TH [Datacenter Hosting] that you are renting has sent you a message!

Is this payout mechanism PPLNS with 10h rounds?
I think the total downtime will be around 48h unfortunately, which is the time fedex express takes for delivery aswell as setup.

Here is the 2 day rental in which I paid .1505448 btc and received back .058 not .0056 notice the time was 1 hour before 10 hour block so full 10 hours lost not because of power outage or natural disaster but because mine operator rented for a timeframe he would not be able to fulfill no notcie to me no hey use pplns or pps etc

Also I recommended Betarigs to someone yesterday I now must rescind that and STATE BUYER BEWARE they allow there mine operator's RENTERS to get away with lying and theft of btc I rented over 37 th/s of equipment over last 3-5 days most all operators grossly over estimate there hash and since you pay a set amount based on their statements not on actual well you get the point but most importantly they allow mine operators to steal from you MUNCHER'S sp30 mines particularly I had rented from this one operator 4 4.5 th/s mines for about .5 btc all under perform but whatever the ISSUE with MUNCHER is he had rented me 2 of the machines without telling anyone he was having them picked up by fed-ex and moved to a new data center Sunday morning???*** fed ex picks up Sundays???*** probably lies anyway I awaken to see 2 miners offline for over 5 hours during which time we completed the 10 hour block this was 9th/s that had hashed 8 hours on that block and paid me nothing I was told 3 hours after contacting mine operator the story of relocating miners keep in mind no notice no warning no please use a pps pool until moved etc i paid for these 2 miners .2+ btc got 0% effective hash because offline before block solve due to mine owner selling what he couldn't deliver and received back an amazing .00564 btc refund from betarigs thanks guys!!!!(sarcasm) If owner had simply contacted me or  stated they would be moving i would of chosen a pps, but no Super Stable always on 24/7 monitored by professional data center etc etc etc is all that he stated      Shame on you Betarigs for paying that mine operator and as i sent to MUNCHER I now will make it a point to flame him for not doing what was right

I know this isn't the main place just making mention I have a Cointerra IV and an s3 for sale the Cointerra hashes at 1.5 th/s consisitently super low reject and hardware rates like .0096% hardware errors and on slush's pool rejects are .2458% the s3 is running most current version of cgminer and hashes at 250 mhz 490-510 gh/s avg PM for details

we submitted it twice same block # as block below it

a 4 second block that was invalid?  wtf

Just out of interest, has anyone here ever selected the option of letting Bitmain (via Umisoo) host their new machines?
The hosting is at a facility somewhere in Mongolia, I believe.

They give this formula for calculating the hosting fee:
Fee = Power consumption * operating hours * electricity cost ($.13/KWh).  So for an S4, that would be approx $127 a month, I think (paid in advance).
My only concern is whether there might be any nasty surprises, e.g. additional fees not mentioned?

The possible attraction of this would be that although I would still have to pay delivery to the Umisoo facility, there would be no 20% UK VAT or import duties.
Not sure how you get the machines back if you change your mind, though.
