Is it ok/safe to run a single unit using 3 cables that have double 6 pins? 8 pin to dual 6 pin.
I was hoping I could run 1 dedicated cable to each blade, then use the 3rd cable and split it between both blades.
The Corsair CM850 only comes with 3 cables.
Thoughts?

What kind of thermal compound is used during S5 assembling? I have Arctic MX-4 and AlSil-3 and I want to try to replace thermal interface and see what it will lead to...
To make water-cooled S5 I used MX-2 http://www.arctic.ac/eu_en

BTW, is anyone able to compare the noise to an S4 please? I have an S4 and had to find another location for it. I had my neighbour knocking on my door asking what the hell the noise was and saying that he could not sleep with it (we both are in separate houses and his bedroom is about 50 meters away from my house). I have seen reports of the S4 between 70 and 90 db but not sure how accurate they were. It would be great if someone could do a test using the same metering device at the same distances for testing both.
Almost identical to the S4.
...
What where the values?
Dogie did not respond to you. If dogie have some Sound Level Meter, then you have already read it from dogies review.

As long as it is non-conductive version, it will work!!

Thank you

Please check your Bitmain Account for the updated coupon counts!!
Yes their are S5 coupons for customers who bought early … Bitmain trying to draw in repeat customers after being burned by bitmain lowering the price . Bitmain needs to come up with a different way to reward past customers because the coupons are becoming more of an insult if anything .
I used a few coupons on the s-3's .
I gave a quite few away.
I sold a couple of s-3 coupons very cheaply.
I would not mind someone tossing 2x s-5 coupons at my bitmaintech account .
my name there is philipma1957

Are there any s-5 coupons? I saw something about s-5 coupons can't find it now.

I have been looking at miner link on the S5. I could use a little help if possible.
Looking at it is the UID is your Bitmain email on account?
Also on Server Addr what should it be set to?
Thanks for any help.

Its not quite ready yet, more info will appear here once its ready.
Thank you very much for info.

If you find any combination of things that help with either/both noise and reported temp, please let us know. I've ordered a couple S5 and plan to try S3 fans and homemade covers. My environment gets very warm in summer.
https://bitcointalksearch.org/topic/m.10095261
Now it's about 10 hours S5 is running with replaced fan, and it's almost silent (especially comparing with stock fan). Temps are 76 and 72 C, but HWE is about 0.0196%.
January 11, 2015, 12:10:36 AM
I keep reading that these machines run warmer. What is acceptable? I currently have my miners in my basement and one of the windows is cracked down there. Temp is around 67 degrees. Since nobody spends time down there it's not an issue.
<65 much preferred, <60s are good.

My miner link will not turn on I'm sure I'm doing it wrong.

The test unit also seems to cut out at 9.45V @ 200MHz even if I start at a higher voltage, and 9.75V @ 250MHz.
If anyone else has had any luck starting these at 10V or under I'd be interested in hearing it.

Interesting. How did you decide to use those frequency numbers? I would imagine that at a lower voltage it may be necessary to reduce the frequency at a lower rate.
can you dial down volts as the gear is running?
if you can try start at freq 150 using 10.5 volts and dial down to 9.75 then 9.5 then 9.25 then 9

Here's my experience with the 2 S5's (batch 2) I received yesterday. Got it unpacked and hooked up and turned on I thought "Oh, hell no!" No way those fans can make this a home miner unless you're talking about keeping them in the Silence of the Lambs basement. Switched to the Silverstone 141 fans on performance mode (1,920RPM is a loud woosh over the scream of the OEM fan) and put them in the back in a pull setup. Turned on and they quickly shot up to 79 degrees Celsius, tried at 312.5M and they stayed at 79. Turned them off and moved the fans to the front (fits fine if you use a bootless network cable) in a push setup, turned them on and they started going up past 70 again, so set the miners at 312.5M and waited. They settled at 70-74 degrees C according to GUI, in a room that's about 75-80 degree F with 0 HW errors. I can handle that, each is hashing about (1,025 GH/s avg.) that's about what my C1 did (1,005 GH/s avg.). Need to get some readings with the Kill-A-Watt today to see how much power it's drawing at 2 x 312.5M.
Here's a little update, so at night the room with little ventilation would get too warm (in the 90's F) and the miners would get too hot, so I added a pair of these fans http://www.amazon.com/gp/product/B0078IWSBG/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 that run at 1,320RPM to the rear in a push pull setup and it drops the temps on the S5's down 4 degrees C. Wanted to go with another pair of the Silverstone 141's but the case they're in won't allow due to space so these fit and work well with the 141's in the front and these in the back.
Upping the freq. to 325M on both brings the Gh/s avg. to about 1,070 ea. (about 1,050 avg. on the pool site) and the wattage at the wall on 230v to 1,100w with temp. at about 69 C (in a room at about 83 F).

Do you have a Canadian reseller with known stock?
Great price, but importing one will kill me

Resellers are unofficial, as anyone can be a reseller. Best bet is a having a good google to see who is listing in CA, then posting here so other members can backtrack or vouch for their legitimacy.

Well, I can see why Bitmain struck the verbiage from their post about running on 9V. This is not authoritative by any stretch, as it's done on a single unit, but undervolting doesn't seem that effective here. I'll have to look into if I can share numbers (it wasn't one I bought for myself or was given as a review, they were purchased by someone for the sake of me testing them for them) but so far I've only gotten the S5 stable at 312.5 at 11.0V, and not stable much under that. If I start at 11V I can lower it to 10.75@300MHz, but I can't get it to fire up from being off at 10.75V at any frequency.
I wonder if Bitmain added that term based on chip efficiency and voltage in testing, and then just multiplied the voltage by 14 for their figures. Hopefully it's just balancing protections added in FW that can be solved later.
