These are the "adapters" I am talking about on tbe Bitmain products.
Others can advise better than me, but I wouldn't expect there to be any benefit to fitting an adapter like that. If you want to duct directly to/from the miner, you can fit flexible ducting over the end and duct tape it to attach and seal it. Just make sure there aren't any sharp bends in the ducting that will increase the back pressure on the fan.
If you'll be enclosing the miners, then a good practice I've seen is creating static pressure inside the enclosure so that air is always trying to push itself out. It will prevent dust from seeping into the enclosures.
While Canaan is better than Bitmain they both suck when it comes to dealing with customers.
It says on their Facebook they received more orders than inventory on 8/31. If they are so high tech and can make these badass miners you would think they would be able to create a website that wouldn't allow them to accept more orders than they have stock.
They have to making money hand over fist how hard would it be to hire a few more people to deal with the orders? I have one of their miners and they are great but interacting with them is one of the worst experiences ever. I get better service buying a $1 hamburger at McDonald's. I mean seriously can you think of any other industry that provides shittier service than miner manufacturers?
If they are still in production or whatever hey that is fine but how hard would it be to keep people in the loop?
After their sale took place on 8/31 would it really be that difficult to send a mass email to everyone that purchased with something to the effect of:
Thanks for your order. We received an enormous amount of orders and are working through them as quick as we can.
Order numbers xxxx to xxxx can expect a BTC payment address on xx/xx/xxxx with shipping to occur three days after payment received.
Order numbers yyyy to yyyy can expect a BTC payment address on xx/xx/xxxx with shipping to occur three days after payment received.
Order numbers zzzz to zzzzz can expect a BTC payment address on xx/xx/xxxx with shipping to occur three days after payment received.
Instead it is like a giant mystery with no one knowing what the hell is going on.
It is frustrating, but you can take a little comfort in knowing that all of us are dealing with the same situation. Canaan and Bitmain are obviously manufacturers, not distributors. The issues they're having are exactly the reason companies use distributors to move their product.
Unfortunately, I'm a structural engineer, not a computer hardware engineer, so I won't be cracking the U.S. miner industry open any time soon.
I'm chomping at the bit to get this started, so I hear your frustration. Unfortunately, it's not going to solve anything.
Here's hoping we both get our orders filled as soon as possible.
