Topic: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH - page 224. (Read 451266 times)

Yes. I have a miner that one side is in the 60s and the other in high 50s. Same machine.

what is the CFM?  Does it push about the same amount of air as the original fan?

sadness.

replaced the stock fans with Noctua NF-F12 iPPC-3000 PWM 120mm

and fired my 2 miners up.

first miner : 58c/54c
second miner : 69c/68c

i realy dont feel like repasting everything :|

anyone else had batches with huge temp differences ?

Until miner link comes online, is there something else we can use to control multiple miners with a single interface? Things like auto restart times, pool switching... etc.

DPS-600 ?

Got an update last night, is sitting in customs right now.

Thanks!

Cool, get all of them, get deaf, then it wouldn't matter when "bitcoin" goes to whatever whether will it make a sound or not-I wouldn't be able to hear it!
hey, this is not the first time I wasted a bit of money on something and enjoyed doing it. YOLO.

These fans are about the same as the the newegg one.  If you notice the flow is slightly more, but the static pressure is the same.  That's probably because the blades of the Delta on newegg is the width of almost 38mm, while the others on eBay you listed are about 25mm with with a 12mm flow director on the back.  So no need to try those, they are the same as the one that comes with the S5 but with a higher rpm.  
If you've got $125 each for a fan, here's the ultimate I could find, posted this a couple days ago.  You'll need a 140mm to 120mm adapter for the 6,000rpm.

yes, this looks like a hurricane (250CFM!). It looks like it comes with 3 pin connector which you can only connect through adapter to molex chain on PSU, not to pins on the miner.
I found another two "monsters' if you want to go for the maximum flow and don't care about sound:

the same fans, but one is coming directly from china and will take much longer.
same on amazon:

With these fans you can probably set a record in S5 speed-I am sure that there are quite a few people here who might try  

So, I ordered a few fans to compare, one of them was this one.  For info. even though the newegg.com site states 2.45A = about 30 watts which is the limit for most fan controllers, this one on the back is actually labeled 3.24A = about 40 watts.  Probably would burn out the fan header on the S5 if you hooked it up directly.  Also, this fan is powerful and loud.  Believe it or not, this fan is even louder than the original one that comes with the S5.

Thanks, guys.

In the US they are M4-.70 x 40 without the fan grille and M4-.70 x 45 with the fan grille. Mine are Hillman brand, got them at Lowe's.

Philips head (or maybe pan?), M4 thread, 42mm long.

Sorry I'm late on this one, the answer is to contact your Amazon seller for coupons. They have control of them.

Thanks, but it is a little cryptic. What is PM? The search for "PM4*42" or "PM4*42 screws" returns nothing relevant.
can you point to the source that is readily available in the United States? Amazon, ebay, grainger, english version of alibaba (less optimal because of long delivery time), etc.

One experiment with S5 cooling you would like to know about: https://bitcointalksearch.org/topic/m.10095270

I've ordered 2extra pcie modular psu cable from modDIY.com

EVGA SuperNOVA is a huge investment here

At the risk of making the proverbial storm in a teacup, bitmain, why do you offer shipping options that you do not effect?

I placed an order for an S5 and selected shipping via EMS, however, my shipping confirmation came through this morning and it is being shipped by UPS.

Just to put this in the public domain, I sent an email to [email protected] and the explanation given was that UPS is faster than EMS, and therefore they opted (without checking with me) to use the faster courier.

The reason I chose EMS over UPS is because the latter charge inexplicably large amounts for processing my import duties, do not offer online payment of duties + charges, unlike DHL are are slower & do not provide TXT status updates and provide a very wide delivery window (e.g delivery before end of day which means I have to stay put till they arrive). I did not mention that the last time I used UPS to ship from bitmain they turned up on the day and demanded cash (or a cheque ... honestly, who still has those?) before handing over my S3. I chose EMS knowing they can be slower, but decided to take my chances. On the day I ordered, EMS was probably cheaper than UPS by BTC 0.001, so that was not a deciding factor. For all intents and purposes, I could have chosen another sticker courier, aka Fedex which was a tad dearer to a negligible extent, but I chose EMS.

Now, when they turn up and they still charge these ridiculous fees, I shall not sign for the package, so it will have to be returned to bitmain, and you can then ship it via EMS at your cost. Pretty frustrating that you offer a shipping method that you do not want to fulfill.

The PSU is powerful enough, but you need to make sure the cables are not heating up. I had it running in a fairly cool environment (~20C) without issues. A PSU with 4 separate PCI-E cables would be safer.

So is a corsair cx750m not beefy enough for these?  I have two S5 running on one corsair cx750m each (which only have two PCIe cables each that split to provide two plugs each for a total of four).  I did have one unit shut off randomly after a couple hours of mining yesterday but I didn't pay attention to whether the PSU had shut off or just the S5.  The S5 was power off though, no lights, no fan, nothing.  Turning the PSU off and back on brought it back up and it has been running since.  The other unit has been running the whole time.
