I think it's OK, but I will consult the board guys day after tomorrow (we have Passower holidays still). You can mail me at zvi@spondoolies-tech.com if something doesn't work on the SW side. We did some testing with acoustic foam chimney, it is possible and does help with the noise but you really need to know what you are doing because if you do it wrong you can burn your house. We do not encourage it and take no responsibility if something happens, but it is your miner Smiley

I am not sure that you will need the fan at the bottom, as long as there is good air flow in front and in back it will suck all the air it needs. The SW should protect the miner from overheating by downscaling voltage and then stopping the miner.
I'm well aware that it can burn my house ^^ it's why i choose heat and fire resistance for the foam.  Shall be good, but i'll have a powder extinguisher next to the room in case of. If the miner stop by itself in case of overheat, it's fine, if not I'll email you or ofc post a message here for a best practice.
PS: enjoy the holiday and have a good rest !

- do you have a very good handle on your airflow requirements? Until you do this you cannot size your fans or ductwork. Essentially what you need is to exceed the maximum cumulative airflow of the built-in fans of all your miners
- once you have this sorted you can size your ductwork and fans. I'd strongly suggest learning basics HVAC concepts unless you have experience in the area. I too have found that found that hydroponic websites (pot growers for the most part) have a ton of relevant info.
People into it gave me advice on the setup. it's renewing more than 25times the air of the room each hour, grossomerdo, the air of the room is entirely renewed every 2/3 mns. I'm using solid aluminium ductwork and everything is fixed with aluminium tape.

- If noise is a concern look into mixed flow fans, which produce high airflow and static pressure but can be very quiet. I'm very happy with my fans from the Soler and Palau TD silent series. Ensure the fans you purchase can handle the airflow temperature! Oh, and buy/use grills on your intakes! Also consider having a spare fan on hand!
~36db for the fan, grills with filter (for dust) already installed. I will buy a spare fan, it's a good idea.

- vertical stacking is great in theory (I actually run a vertical setup) but keep in mind practical considerations like access to power/data connections both at the wall and to your miners. It also can be much more awkward to swap equipment.
about the connections, i've already worked it out, my installation will fit perfectly -i hope Grin-
for the switch of equipment, its a concern but I trust SP to make good equipment that does not fail every week.

- do you have a plan for how you going to channel the air to force it through the miners? The airstream will take the path of least resistance, and the last thing you want is the air going around your miners and not through them
yep, the grey part will be stick, not attached, to the pack of appliance + a fan below.

- you might want to look into ($$/size/noise) a central ac system which will support your airflow requirements in advance...
- I've found a thermal camera (e.g. Flir) is an incredibly useful tool (!!)
not relevant for me yet... i can cool down the house with only one AC. but i like the idea of the thermal camera !!

- finally, consider the impact if one if your fans fails in the middle of the night - I'm not overly familiar with Spondoolies miners, I imagine they have thermal shutdown capability?

zvisha answer that :

The SW should protect the miner from overheating by downscaling voltage and then stopping the miner.
