Vertical airflow sucks for actually dealing with that heat once it comes off the units, so unless you're in a multifloored data centre with floor to ceiling airflow, you're just making it more difficult to expel that heat. At least with horizontal flow you can then DO something with it, ie move it elsewhere / outside.
so much bullshit... the point is hot air rises and cold air descends, but that is hard to understand for you  Tell me about it! And what exactly is that which you can do with horizontal airflow that you can not do with vertical airflow in a non data-centre setting? I'll, for the umpteenth time, put it down to dogie-waffle. Move it out the room? I don't know about you guys but I don't have doors / windows on my ceiling... A wise man changes his mind, a fool never will... |

Yes, and ducting doesn't exist in this world.  |

If there is no mention of ducting, neither is there of windows or doors, but that did not stop you mentioning them, did it now? In any case, what sort of windows and doors do you have on your house that will refuse to let vertically exhausted heat out? Do you live in a gnome house, have floor vents for windows & trap doors for access or is your house built atop a black hole where the natural laws of physics, aka heat rising, do not apply?

I have to say in Boston it is about 15 degree F. If I open a window I feel the cold air passing down from the window to the floor; it would probably take 4 or 5 thousand watts to increase the ambient temperature to anywhere near the level where this would not happen with the window open. I know this because last year I maxed out all the circuits in my apartment ~6.3 k watts.

Overclocking voids the warranty? Then why is it a drop down option in the control panel of your software which ships with the units. I'm not trying to start a fight here. But I find that it's ridiculous to put an option to set a frequency higher than 350 with a simple dropdown menu - in your own software - and there be no warning whatsoever - and that BM would deny a warranty claim.
Yes it does. I can't really answer on behalf of the other questions as its not my rules. I added an overclocking question to the wiki. Is overclocking allowed?
Users may overclock at their own risk but overclocking WILL invalidate the product warranty. This is a more official quote if you will, there is a bigger quote but this is the best one I can find with search as it is. Over Clocking will void your warranty on the unit, please be careful  That is your usual waffle! There is NO official literature on overclocking voiding the warranty, and your quotes, wiki additions and public forum quotes by a bitmain employee can not be used as binding statements to bitmain. Like I said, waffle as usual! Add to that, Strato (or anyone) is not obliged in any way to add a warning to their threads regarding any statement as to OC'ing voiding their warranty, if only because even bitmain themselves do not mention that anywhere authoritatively. You, dogie, are a simple dogs-body for bitmain, toothless dog if you want, as your assertions are not worth the digital ink that they are written in (let alone have the force to void a bitmain warranty)! PS: And stop being off-topic here, if you are so concerned about the warranty warning, go and open a thread in the scam accusation subforum or press your favourite link to report to the moderator.  X 1,000,000. Spot on. So Dogie, is it expected that if somebody who doesn't belong to this forum purchases Bitmain's equipment through their website, they should have to search out 1 quote on an online forum to realize that making use of a built-in feature voids their warranty? Without ANY mention in the software, literature or on the website? Get real... |

I mounted my lone s-5 pointed to the ceiling. I am overclocked to freq 412. results with window shut I will open window and show resuls in the morning. it is 20f in New Jersey window will open 1 inch.  |

Wow, its a bit hotter on the temp but this is hanging from the ceiling? (High in the air where it is warmer than the floor?) I mounted my lone s-5 pointed to the ceiling. I am overclocked to freq 412. results with window shut I will open window and show resuls in the morning. it is 20f in New Jersey window will open 1 inch. |

I wonder, simply out of curiosity alone, if reversing the airflow - basically flipping the fan over... "Shes gone from Suck to Blow!" would result in better or worse cooling.

Phil, did you simply point the miner towards the ceiling as your post says, or did you in fact mount/glue or tape the S5 "to the ceiling".  Strato |

no it is on the floor next to the spare bed. I just checked it and the room is too cold with the window open. Here are the numbers on the 1 piece. I will post some photos later.  that is a stainless steel grill it allows cold air to be sucked up from the floor. it was 73f on the floor with the window closed  window was open last night that 9 volt battery is for scale  the grill is spaced to let air in  close look at the ss grill  the actual fan grill is spaced about ½ inch  |

Dogie is correct that the air escapes from the bottom and top of the unit. see this photo. Dogie is wrong that it is not cooler at least in my case. It is cooler this way with 1 unit in a 12 by 12 by 7.5 very well insulated room. It is 1 or 2 f cooler with the window shut. It is 4 or 5 f cooler with the window open and outside air was 15 or 16 f this morning a lot of air comes out of the bottom of the unit. IN this photo now the bottom Is a wall of aluminum heat sink facing us I am going to make a solid bottom over the weekend will post on Monday. look close I have a few heatsinks on the unit. |

scotch tape all the bottom from side to side. scotch tape as much as possible the top of the unit!
Philip, u need to raise the unit a little bit more. ~4inches might be the best....

I will use some painters tape as it removes well. The closer to the floor the colder the intake air is. I may raise it : 1 more inch then 2 more inch then 3 more inch then 4 more inch to find the sweet spot. I am doing a solid 1320-1335 gh and not that hot. |

yes, painters tape is good too
why i said to raise it, is because the fan is really obstructed the way you have it now.
the difference in temp from floor to 10inches above floor is almost none, but a good airflow is best!

I will attempt to raise it later you may be correct about the fan blockage. The tape seems to be helping. this is a new number with window closed. very good hashrate but early.  |

Philip, Have you found that on your test miners that there are Frequencies that work at higher points rather than lower? Example - I have most of my miners at 392.75 - some at 400. Some got x's at 400. Is there reason to think maybe that a miner that x's out at 400 - might actually work at 412? Cheers, Strato |
