It is spring here and Australia and the temperature gets over 45c here in summer so I will be looking at adapting my S7's to the Syscooling S5 cooling kit

http://shop.syscooling.com/goods.php?id=51

I would prefer to not get into a debate about the kit itself but would like to see if anyone has any suggestions about making it work. It appears as though the S7 hashing boards don't have screw holes in it so I will likely have to rely on thermal adhesive.

Also does anyone have any experience with the thermal strips supplied with these cooling kits? Is it worth using, is it a thermal adhesive or just a paste?

I understand that Syscooling had some dramas with a water pump they were supplying when they started out. The pumps that came with my radiators are a sc-750

http://shop.syscooling.com/goods.php?id=26

I am a little unsure as to whether I should trust these pumps because there will be about $2500 riding on each one.

I would rather use water cooling then to use A/C because if I go the A/C route I won't be able to run as many miners.

Cheers

I agree with not going into drama on it.  But if you do I suggest an upgrade on pump, don't go with that.

I had 2 C1's I used - http://www.ebay.com/itm/381066536924?_trksid=p2060778.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT on and works good.  So if you find a way to watercool by modifying i suggest a pump similar to that work great and lot bigger resivour.

From all the tech specs and data, the S7's will use bonded individual heatsinks.

Unfortunately I wager that removing these to apply a large cooling block would damage the chips / attachment to the board.  In my experience removing these kind of bonded heatsinks is very touchy.

If only we could get Bitmain to send us some raw boards to work with...

Sounds like room cooling solutions such as those already presented may be your best option for this gen of HW.

Chances of ROI with 6 of these + 25% VAT? (The differences in VAT is kinda depressing)

I would highly suggest looking for a hosting data center.  I'm all for home mining but at 25 vat that's just to much of a disadvantage unless you have extremely cheap electricity.

What country are you in?

I am not an electrician. Can somebody please tell me if I can run one of these on a standard outlet for an apartment in the USA? I would buy the power supply that bitmain sells.

Yes. It only uses around 12 amps I believe. Most U.S. circuits are at least 15 amps, and yours are probably 20 amps. As long as you don't have a bunch of other things plugged in on the same circuit you should be fine.

Thank you sir. I just checked and the coupon is indeed in my Bitmain account.

You are correct but its important to look at the wiring coming from the electric panel. A lot of newer homes use a 14/2 wire and are a 15 amp circuit and if a 12/2 wire was used will handle a 20 amp breaker. Not so sure I would use a 15 amp circuit if your pulling 12 amps 24/7 better to upgrade to the 20 amps.

EDIT: I just seen that the PSU from Bitmain is a 220V so you would need to have a 220v outlet which in a apartment would only be if you have a electric dryer or electric stove. So I dont think it will work well for you.

I've considered it, but there really isn't any real options out there. Do you know any?
This guy looks promising: https://bitcointalk.org/index.php?topic=1159107.0

I've already sent the money, no going back now! ^^ But I would consider something like the guy in the link above for future orders, if he turns out to be legit!
Paying about 0.06$/kW atm.

I'm located in Trondheim, Norway. I'm still running the S1's tho.. I know its kinda dumb, but I love it! Besides, they heat the house.. https://www.youtube.com/watch?v=aJ_kJLGYxRQ
I will replace them with S7's when they arrive. (And rebuild the room to get more of the heat out).

 No, the Bitmain power supply requires a 220V outlet, which most apartments do not have.

 If your apartment has an outlet for an electric dryer or an electric range, you COULD hook it up via that and it would work.

 If you use a standard ATX type power supply of 1200+ watts with enough PCI-E cables, a standard 15A 110V outlet WOULD handle that.

Chances of ROI with 6 of these + 25% VAT?

 Depends on your electric rate.

[QuintLeo]

But S7 coupons are rare, and at last a long time

 rare, perhaps. last a long time, NOT EVEN CLOSE.

 ridiculous price

 The S7 is arguably priced a bit high, but for the performance it offers the price is not "ridiculous".
 I was figuring it would be a 2.34 TH 550ish watt miner pre-release - at about 4 BTC.
 Instead, it's over twice the hash at about twice the power for right about twice the cost.

I ordered 2 of the Bitmain power supplies with my 4 S7's to test out with these, but am slightly concerned with the low AWG wires

 18awg should easily handle 180ish watts - that's only 5 amps per wire.
 Come to think about it, THAT might be why they state "have to use all 3 connectors" - wire limits on the PS they tested the S7 on.

Will S7 be available for redemption at hashnest anytime soon?

 You're joking, right?
 Probability ZERO if you're not joking.

 Hashnest is only JUST IN THE LAST WEEK OR SO prepping redemption of the S3.
 I'd predict S7 won't be redemption material for close to 2 YEARS.

I recently moved to a pair of Bladecenter H 2880w server PSUs ... But they're also the opposite of quiet...

Thankfully they are 8 miles away in a colo rack. I can barely hear them from here

 Better get your hearing checked, you seem to be starting to go deaf.

 9-)

ROI before next BTC halving is a no go.

 Not if your electric is cheap enough, though it's a near thing.
 On the other hand, these units SHOULD BE STILL PROFITABLE AFTER THE HALFING for a while - even if we don't get a pre-halfing price runup like Litecoin got the last couple months.

It's hard for me to tell by holding a S5 water block up to the screen but it looks to me that if you were to take a heat sink off a top chip and a bottom chip, the water block would just cover both chips. Would you mind having another look for me?     

Any help in advance is greatly appreciated. Also, how hard was it to remove that heat sink?

Bottom side is no chip under the radiator. You can not take them away.  They must remain so.

I did not  remove the radiator. This was already   so , when I opened miner.  The blade   go back to China. Soon.

the components between the asics, look higher than the asics?

can the wb lay on the asics or will it lay on the other components?

thx!

I think R207 is higher, then asic chip.

8 BTC? Ouch.

Yeah. For me it's almost 10 BTC (including shipping and other expences especially for those who needs shipping to Russia). 

May i know the reason why would you buy so expensive when the ROI is too long(at least for me)
I am a miner fan but the roi take just to long.

Interesting. I'm sending one to Toomim Bros for hosting. They also have a deal on a PSU for just $80. I am not being paid for this message
