The reduction in size from the rectangle to the tube may be too much and cause overheating.
The tube being short under three feet helps.

right now I have 4" 3d printed piece on the back of the current S9's like this
which directly connects to one of these - immediately opening it from 4" to 6" --- originally I ran them as 4" directly outside but decided 6" would be better, rather then make all new pieces to hook to the miner, I used a 4" to 6" and just ran the ducting from the adapter to outside (distance to outside is less than 1 foot. The air does not have far to go before being vented.
so my idea is to use the 3d printer to make something similar to this shape that will mount to back of miner and hook to my 4" to 6" adapter - thus the only thing I am replacing is the piece on the back of the miner.
the other idea is to just make it 6" remove the 4" to 6" adapter completely.

exactly - so i am thinking of doing double tall same width and exit to 4" for mine only because I already have 4" to 6" adapters on the 6" ducts already but I still have some on 4" ducts as I upgrade those to 6" i will forego the 4" to 6" adapters and just use a 6" right off the miner. eventually will swap them all out as the ocd aspect will bug me lol.
you want to shrink from say a 6 by 12 opening (the 2 fans) to 1 four inch duct hole?
or from say the 6 by 12 fans to 2 4 inch duct holes?
I would be pretty certain you will need 2x 4 inch ducts minimum

I wonder if they move double the air, does the S9 move 250 FPM, S15 500?
yes maybe not 2x but yes more.
it is more like 2 short tubes
vs 1 long tube.
for cooling it is a better design as the air only travels say 9 inches in this design
vs 16 inches in old design
so a 250 fan >>>say 16 inches>>>> 250 fan in 1 tube does at best 275
vs a >>>9">>>250 fan
>>>9">>>250 fan much closer to say 400
so the exit ducts need to be 2x the size.

I hope to get to it this weekend - if time allows - really just need to take measurements - looks like it will just be double length - if so, can widen one end and still leave it as 4" or even as 6" exit
I placed the regular ones from the S9s that have a 5" exhaust (120cm wide I think) to check, and they don't fit properly, so maybe you will have to play a little bit more... Double length adjustment will not be enough, since the screws in the corners are like 1cm away from the S9s ones.
If you could to 4", 5" and 6" versions that would be awesome^awesome really

Yes, PLEASE!

i also notice no exhaust fans - I will have to come up with something on the 3d printer so I can hook these to my exhaust ducts
Yes, PLEASE!

Oh please share Stryfe, I am also "Ducted".
I shall

So basically too loud for home use unless you have a dedicated space where you can sound deaden the space?
After the R4, this has been the only design consideration for the asic miners. They belong in an industrial warehouse, therefore noise doesn't matter, and it shows... However creative thinking can overcome part of this problem, such as using a wooden box with noise insulation fabric inside. I have seen others sell noise muffling kits, for S9s etc, but with varying degrees of success.
The S15 could fit inside a box in a garage just like philipma1957 did. My thinking is that, a box should be something like this (when viewed from above):
Code:
________
| / |
| S15 |
|_______/ |
With the holes being full rectangles and not circles. All the walls inside this wooden box should be covered with noise insulating fabric.

Yeah the biggest issue noise-wise are the power supply fans.
The psu fans produce a really annoying high pitch noise.

Sound proofing my access door has been instrumental for my living space noise wise. Though my s9i LPM is quiet as hell. I think most complain about the PSU fans more than anything else.

oh yea you are not putting an asic in your general living area - they are quite loud unless you take measures

Great review HF, thanks.

nice review - I just wish they were not so expensive to buy - the roi time frame makes them pretty much useless.

Good break down. Long term I'd be looking at the s15 mostly if on my own. Though imagine a group buy for m10 would fair really well in bulk pricing. Thinking further still what t3 efficiency mode looks like and how it would look pending volume.
