Not going to the very hefty price but its a great idea.
Anyone know where I can get my hands on 6 or 12 of these?

Watch for overheating.

The reduction in size restricts air speed.

Look into flex vent from Home Depot use bigger like 12 inch put the whole miner in it.

Just about 1 foot inside on intake

 put a small  hole in the vent to allow your pcie cables .

Then make the exhaust side as long as you want .

Just go to Home Depot and search for flex duct 12 inches or 10 inches.

He wants something that screws into the fan/mount.

You could probably repurpose one of these, in the worst case cutting them in half to get 2x and then using tape to join the duct to duct ends.

I had some made up on a 3d printer.   They raised temps 3 to 6 c.

So I do not like them.

yeah but you could always drop some ducting down from a ventilation fan that is pulling upwards of 150cfm and split to multiple miners to draw away the heat.. ambient would benefit and the result would be a push/pull for the S7F1 at minimal cost.

thanks for the link

your ambient is a lot lower  ( I am 27-31)   which may be why you are good.

My miners are 62/61/63 with fans at 3000 rpm
