[GUIDE] Strato's Antminer S5 Vertical Mounting Setup Guide - Updated Photo/Video

[toptekk]

Curving the blades essentially allows you to pack the blades closer together, so it will increase surface area at the expense of increased resistance to flow. It's essentially the same as using shorter fins, but packing them closer together so you have more of them. It makes machining the heatsink easier for the same surface area though, so there are good reasons to do it.

Stratobiz, have you tried just removing the box fan? They definitely move a lot of air, but the linear velocity of the box fan is going to be quite a bit lower than the big Deltas. It'd be interesting to see how much of a benefit there really is.

I think this is for the most part spot on, however I do not believe that airflow resistance is increased with the air flow running parallel with the curve of the blade/fin.

I could be wrong, but I believe that resistance is only increased when the airflow moves over the blade like the wing of an airplane.

I haven't tried a 2nd Fan. May give it a shot.

Home depot was out of box fans when i went there to day i had t order one due on 11th to my house .

 once i read this i knew i had do it .  


ty  can't wait for the software end of it now. if you have a BtC address i can send something let me know it won't be much but some thing for a few beers if you drink them .


Sorry about that pst I sent , I was wondering if you were working with that guy.


well any way I'm glad some thing like this is here.

 My next buy is a https://ehash.com/product/avalon4-module-1t/ I discovered to day Webb hunting.

No worries and no payment is necessary. Yea sorry my response to your PM may have seemed odd, but I had no clue what you were talking about and thought you perhaps PM'd the wrong person.

Good luck!

Also This is a MUST:  Pro-Tie Brand Zip Ties. Yes they are more expensive. But they dont snap, break, or become brittle over time. 100% Worth It.

Amazon Sells every length. The long ones (30" and Up) are like $1 each but you can literally ZipTie a 30 Lb Large Object to the Ceiling and it stays put.

Heres their product line: http://www.amazon.com/s/ref=bl_sr_hi?ie=UTF8&field-brandtextbin=Pro+Tie&node=228013

Strato

I got the ties from home depot for now . ty for that link ordering some off amazon.

Here's a snapshot of one miner:

[SockPuppetAccount]

Is that your bed next to an SP20 & a S5? Do you sleep with industrial ear muffs strapped to your head?  

That is dedication.  Definitely could keep a eye on it that way though.   I personally keep them out of bedrooms

You stop being able to hear it after a while, its surprising what level of noise can become the baseline. Its also a lot easier because miner noise is perfectly level.

I own a very small house.  Only 400 square feet total.

So, I have no choice but to keep mining equipment within my living space.  Also, I am an on and off smoker and like a clean smelling house, so I run a HEPA air purifier on turbo speed 24/7.

I sleep like a baby with 2 SP20s and 2 S5s running at full tilt about 3 feet away from me.

If I turn off every fan in the house, it is uncomfortably quiet.

200% true!

  along his idea use  this idea:

 use the box fan as a pull   on top of the s-5's

Philip are you suggesting using 2 Fans in a push pull config?

My only thought is the config I came up with funnels all exhaust directly up. Its pretty warm air- and those box fans are PVS plastic. I think over time the blades of the box fan would warp due to the warm air heating the fan blades and the friction caused by the air the blades are pulling upwards. You could end up with a back draft effect where warped blades result in choppy airflow and cooling may be impacted.

Just my thoughts.

Strato

   you may be correct that the box fan would over heat.

[MrTeal]

No offense, but if your exhaust air is hot enough to melt or warp plastic, you aren't moving anywhere near enough air. Six S5's is still only ~4kW, which isn't that much heat. If that box fan actually moved 2500CFM as claimed, you'd be talking about an air temperature rise of ~3C.

[HolgerDansk]

Stand the Miner Vertical.  Set it up like I drafted it out in my Op Post. See the heat difference. See the OC capability difference.

Yesterday I tried just simply standing my S5's vertical.  The temps dropped.  Strange, but Strato's right.  With mine, I pointed the airflow down to the floor, since cool air is coming in from a window above the miners.

With the miners laying horizontal, and cool outside air pouring at the intake fans and on top, they run hotter than when it's vertical.

Thanks for that tip Strato.

Glad it worked for you. But am I reading your post correctly that you are exhausting the hot air down?  You should exhaust up. But regardless, yes standing the miners up vertical results in better cooling efficiency.

I dont think its a matter of melting... But rather simply the fan blades of the top mounted box fan being subjected to 100 F or warmer airflow over long periods of time. The blades may deform slowly. Im running 24 units in 4 banks of 6. Only a single mounted box fan as illustrated in my first post.

Mr Teal mentioned the plastic warping temps as a symptom of the problem, not as the problem itself.

Depends on what they're made of, but they should still be fine. You would need to get into some serious temperatures before you'd see softening of the blades, and the miners would have destroyed themselves long before that.

Even if your input air is 40C, your exhaust air will still be under 50C. I don't think the S5 would operate in much over 40C ambient, although that would be fun for someone to try.

Strato

Yes, I am venting down.  Only because of the height of my window bringing in cool air, which dumps neatly above the miners, so I wanted to pull that cool air in as it naturally flows from above the miners.

I knew venting up, would be more logical.  But with the cool air coming from above the miners, I thought I'd give it a try.  It lowered my temps.  Thanks again!

If you really want to lower temps, duct the window so that all the air is forced to flow through the miners. Not only will it ensure that the input air is at ambient instead of being hot air recirculated around from the exhaust, but it will help suck more air in from the window.

[Stratobitz]

While I have yet to try I believe that doing a vertical miner setup with the S3+ Units would also improve cooling. Warm air exhausting directly upwards at floor level will result in the least amount of exhaust air being recycled back into the intake as warm air rises all on its own.

Perfect idea.  I'll have to set that up this weekend.  Thanks.

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.

[kreativling]

Strato thank you for sharing this idea of vertical mounting. I just tried it out the last few hours and had some interesting results:

1. Avg. temps are the same, but before the S5 was laying on the floor, now it is 1m higher, so the room temperature there is 1 or 2 degrees higher for sure - so the cooling of the unit must have improved

2. One blade was always at least 5 or 6 degrees hotter before, now it is only 2 or 3 degrees, sometimes even the same temps

3. Hashrate has only slightly improved (still waiting for long term results)

4. HW error rate is down appr. 15%


I will continue with the vertical setup and see where it goes.

Thanks again.

Move it out the room? I don't know about you guys but I don't have doors / windows on my ceiling...
