Thermal conductivity of Arctic Silver glue (!) is about 10 times higher.
So your Arctic 3M8810s are 1) unefficient (comparing to thermal adhesive) and b) dangerous (what if heatsink will drop off and make short circuit somewhere?).

What about thermal conductivity of those stickers?

Well, you can place it to A plates to provide additional heat dissipation from the chips. Those big heatsinks from another side of the PCB are not enough (it's all about S5's design, bud!).
Be sure that you chose best and non-conductive thermal adhesive (I guess that Arctic Silver will be the best choice for you).
Also check the size of that A plates before applying thermal adhesive.
Speaking of B positions, you maybe can stick little heatsinks on these capacitors too, because they are really hot when S5 is running. But the above step should be enough...
Pay attention to the fins of those heatsinks, it should be oriented accordingly to airflow from the fans (yes, you better use 2 fans if you decide to stick the heatsinks).
p.s. speaking of philipma1957's pictures, you can just play the fool with temperature sensor sticking a heatsink there, but it shows a "weather on Mars" even without that. Just "something like a temperature, somehow related to actual working ambient right near the chips across it".

I'm keeping an eye on your research. Good luck!  |

Well, at least Bitmain is here with us and keeps promising. It's better than nothing... If i would ask for advice, to buy another S2(s) or not to buy - what would Bitmain answer?  |

I am glad to see that this information was useful for you.  |

For the same price, you can have 3xS5, more efficient and hashing at 3400-3500 GH.
Bad timing to release this one, or the price should be dropped under 640$.
You will need to provide a PSU for each or both those S5... S2 upgrade kits with BM1384 would have been better right now, or some kind of S6.
Yeah... We are still waiting while Bitmain keep silence... And may be they will continue to keep silence since S4+ should be sold... |

Whoa!!!
1. The included PSU cannot be used in countries with a mains power voltage lower than 205V. The PSU will not start below this voltage.
Pretty much has no market in North America then.
You can always use any server PSU, and this one (stock PSU) - sold it to someone who need it or try to ask Bitmain to ship S4 without PSU. I would prefer to buy it without PSU in any case (less shipping price, more freedom to choose reliable and powerful PSU for overclocking). But with such a price, with such a BTC price, I have serious doubts that I will buy it ever... |

hello you've tried this with firmware 4.9 cgminer por antminer s5? worth it? really better? or worse?
Hi! I downloaded it but have not flashed yet. I am satisfied enough with old S5 firmware. I don't like Nicehash. p.s. have just flashed it, looks OK. CPU load reduced from 80+% to 22-27%. |

What is required/desireable wattage of PSU for Lightning X6?
|
|
|

well if you mean 'interested parties" in the board.....(ie a working unit even in beta i can help you all with by running etc) you can count me in
if you mean a 'sample board' with test chips and you expect me to know wtf is going on with it ....er probably i should wait till you get the stuff out in production
but hey....I'll turn anything on you want to send me to test 24/7 if the above is...
Well, I would like to play with your board (in the way described in the quote) too. Probably. |

Bitmain has no interest in selling any hardware. ...PLUS their outrageous shipping cost? Indeed... |
|
|
|
I have the idea too, that Bitmain is fucking us S2 users over again...
I beleive (what else can I do?..) that they will once send me this upgrade kit for testing and review.  They can't fool us twice I guess. |

Идеи о вводе рубля на фоне его стремительного падения уже даже не рассматриваются.
Просчиталесь, блеадь? (См. сегодняшний курс рубля.) |
|
|

Ну на bits.media идею уже достаточно освистали, да? Не буду здесь этого делать дублем. |

We're looking at building bigger boards, specifically one half the size of an S1 blade and one the size of a prisma board, to refit onto existing heatsinks.
novak
Like those that can act as a replacement of existing S2 blades?..  It looks already that Bitmain will never release such a boards........ |
