What is the potential for damage by running these in an hot environment? Where I work, our server room is pretty damn hot. Right now I run my miners outside my home. Its summer in Australia and its pretty brutal. My miners see 35 - 40c days and hot nights.

Should I be concerned running something like an S5 in this environment?

i think you will need to run at freq 275 to freq 325.

Not sure that I understand how this works.
For example, would this work (say, with CX750M that has only split connectors):

D D
|  |
|  |
|  |
|  |
D D
 ^
fan

I think that it should, I always used doubles on S3 like this. Or has it to be

D---D


D---D
  ^
 fan

Or criss-cross? Or does it matter?  I thought that a single rail system will balance the power draw at each 8 pin connector at the PSU (actually this is where he melted it). That is, I thought that 200W power would be drawn into each 8pin connector if you have 3 cables connected (at the PSU level) to a single 600W miner. Incidentally, since CX750M has only two cords, each would definitely draw ~300W at each 8pin connector while powering S5 at the default speeds.
Maybe I was wrong thinking about PSU balancing power, but would like to hear the physics behind the setups.

in your case it does not matter   and it will be very hard to run at  freq 350 since your cables should not use 300 watts 24/7/365

the reason it does not matter is you are using 2 doubles from one single rail psu. do matter what you do on one s-5 the cables will be asked to pull 300 watts
_______________________________________________________________________________ ____________________________________________________
In the evga 1300 g2  case 3 cables per s-5 need to be plugged  in the right way to balance the load over each of the three cables.
-------------------------------------------------------------------------------------------------------------------------------------------------
BAD  not BALANCED

D S   left board  only uses the double cable the board wants to pull 300 watts = cable melt
|  |   right board shares 2 single cables the board  wants to pull 300 watts = 150 watts  for each those cables are fine.
|  |   this is an non balanced load to the psu bad

It's unfortunately not that simple; there's no guarantee you'll get a 200/200/100+100 split on the three cables. It won't really matter in the end as you know for sure that you aren't pulling more than ~25A per board even with a bit of an overclock, so you have a lot of headroom there.

In the case of the CX750M, I'd probably recommend going with a single double ended cable to each board.

as long as temperatures dont read much higher than 60C youll be fine i think. fan might get pretty loud though

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461 also selling 6" M-F-M PCIe splitters and PCIe-PCIe

That's crazy ! You must have some legendary S5 that was forged in Mordor... or something...

EDIT: Board temps <60C ?

Yes, the stock fan is quite loud, but it maxes out long before the ASICs register 60C, so unless I do a fan mod the high temp is not the cause of the noise. The heatsinks themselves are barely 50C, so I'm not worried about it at all.

I clocked to 412 with temps at 58 and 56
I sold this miner to a local  miner from this forum.
 his setup will allow the loud stock fan and the delta 3 pin  which runs between 2800-3200rpm.

 I did my last test run this morning pretty good numbers if you don't mind the nasty sounding  77db fans.  this got about 1300gh at 676 watts that is close to .52 watts per gh  and maybe 10 watts is from that second delta fan.
 the stock fan 4 pin  (3900rpm) is the push
 the delta 3 pin (3100rpm) is the pull

I'll be ordering two of these when my last miner is gone. Noise doesn't concern me, the Bitmine unit I have here is noisy as all hell and is unbearably hot to run.

if noise is not an issue they are pretty good.  I sold mine and he has an added pull fan.  it clocks to 412 and temps are about 58c.

if anyone want this miner and also want  away from the noise at the same time
you can go for me

i provide host service for s5 and charge host fee according 0.1$ per kw'h
which means if the power consumption of s5 is about 600w, the host fee for one s5 is 0.6*0.1*24*30=43.2$ per month

i am not scamer, i have provided host service on this forum for more than 6 month, even philipma host one a1 miner in my data center for three month

I did business with pcfli  and he was okay.   

He may be good for you if your power is too costly.

I am not sure how he is setting up hosting of this gear.

 lee put up  a link to your thread  if you want to.

To anyone  that uses pcfli I get no money from lee.  And while the deal i did with him was okay I do not know the future .  His place is in China.

 I do not know any details and I do not know if it will work out for you.  Lee  sold me and hosted a dragon miner for me for 120days and then purchased it back. His service was good not perfect. Say April 2014 to August 2014.

  I  broke even on this more because of good btc price sales on my part.
For the 120 days of hosting I was up and hashing around 118 days. Which was more then 98% up time.

Thanks philipma for the clarify of my service
those s5 gear will hosted on our big farm in chengdu with good stability, which have run for two month without any downtime
i will get my thread ready for the s5 tomorrow, but if you want to check my record, you can go
https://bitcointalk.org/index.php?topic=514758.0

we will test the real power consumption of s5 when it arrive and charge host fee according to 0.1$ per kw.h
should be around 43.2$ each s5 per month.

I maxed at 1290-1305 at freq 412 with a second fan for cooling it used 675 watts.

I'm surprised that the discussion about replacement fans are more focused on their airflow volume (CFM) rather than static pressure (mm/H2O) which is more significant in heat sink/radiator applications.  High static pressure fans are more capable of penetrating through dense heat sink fins such as in the AntMiner devices.  I think there's a reason why Bitmain engineers equip their units with very powerful industrial 12038s with high static pressure (directly proportional to loudness) instead of just mainstream consumer-oriented 12025s.

For better cooling results without a shroud configure your fans inwards as push - push  not push - pull

I did tried on s1 and is crap! the hot air was getting stuck in the middle and temps rose like ~5c!
putting the unit on the side may help Roll Eyes

true in the case of  one  push fan only.  but two high cfm fans as push pull get around that.

 since neither one needs full penetration of the heat sink using high static pressure,   but if you don't care about sound the stock fan with a good pull fan cools best.
