Put the Jupiters near an open window or open door.
Make sure nobody can enter your house, protect the window or door with a metal fence that can't be penetrated.
Point the miners with the direction of the outtake to the door or window and blow the heat directly outside the room.
The intake of your miners are sucking air from the other rooms and there is circulation of air.
Your room will not be hot.

It is already summer here in China with ambient temperature above 30 degree celsius.
This setup proves to be working.
Now I am replacing all the fans in the miners with much greater airflow than the ones originaly in the miners and it's even work better than before.
More airflow is more noise, I don't live in that house, so it is not a problem.
You are living in the same room as your miners, so you have to decide wheter to put the Jupiters outside or experiment with this idea.

It's the morning dew which should be a concern or just moisture in the air.  If it's housed inside the cabinet it may be ok but fans sucking in moisture if it rains will kill it.  I have a shed that I thought I would place my miners in but I live where it rains a good part of the time.

I have 4 S1s in the garage. I use this to shut them off if it happens to get too warm (and turns them back on when the temperature drops), although it doesn't sound like you will have that problem.

It is pollen season now, but they are pretty clean still. I was thinking about one of those big plastic storage boxes where I could truly put them outside, but I haven't spent enough time trying to figure out how to make ventilation water tight and still maintain enough airflow since I do have some windy rain at times. There are NEMA rated enclosures but I'm not interested in spending that kind of money on this little project since it is only really useful in the summer.

I built this thing last year

basically same sort of thing, just pulling lots of air in and out. If you go that route make sure to get in-line blowers, I switched to those fairly quickly.

No need for this. From my refund, I went back through the blockchain and found that KNC pools a slew of BTC (900+ on my refund day) into one address, then creates a new address for each refund, sends the appropriate number of coins to the new address from the pool, then sends the refund to your address from that address.

I followed KNC's refund on blockchain and found 3 address with well over 20,000BTC in each earned from mining, can also see they get the full 25BTC for finding blocks.

note. I an amateur when it comes to blockchain snooping, so not sure I know what I'm doing. 

When I asked for their banking information, they wrote:

For Bank Transfers;
In the reference please add your order number only (no product name) so we can track your payment
Payment must be in USD.
Please use the following details:

Bank Name: SEB (Skandinaviska Enskilda Banken)

KnC 20nm AB address: Birger Jarlsgatan 33 5tr, Stockholm, 111 45, Sweden.

Once I have all the documents from the Swedish registry of commerce, I'll post them here.

This was my first thought, too.

kncminer.com is owned by Kennemar & Cole AB. The Neptunes which I ordered were paid to KnC 20nm AB, while they write on the homepage that the content is copyrighted by KnCMiner AB.

KnC Cloud is operated by KnC Group AB while the domain is owned by KncMiner AB.

We all do not know how they have transfered the assets internally and if they have intercompany loans.

They once wrote that they make 400'000 US$ per day by mining. This is, however, already a couple of diff-adjustments ago (gosh, do I really start to measure time in diff-changes?)

Maybe because it costs a lot more to do that than build a cheap ass datorhall with old kit that they can knock out a 10c a dozen?

1. No way they can declare bankruptcy whilst declaring "a million kronar a day" in fiat.
2. Embezzle? No need when the deception has been done, and have "a million kronar a day" to wallow in.
3. How does one "embezzle" from a personal wallet thru mining again? (Your #4 makes absolutely no sense mate)
    "There is nothing that proves that they are not allready embezzling using personal wallets to mine to at "our" DC up north."
Huh? Mine with a wallet?  Have you ever mined Bitcoin?

If you meant our money from our preorders...  Well, one could also argue the fact they made plenty from Jupiter and Saturn previously, under decent terms.... plenty enough to cover Boden.  I'm not sticking up for them here, but there's no sense in dwelling on this too much... we in this thread have been over and over this information hundreds of times examining the facts, and your assuming they used preorder money for Boden doesn't hold water.
There's absolutely no evidence of embezzlement here...  dishonesty, and deception; yes..... embezzlement, no, sorry can't agree.
Embezzlement would be more like a KNC employee siphoning funds to a personal address at KNC's expense... and frankly, I'd give a shit less about that... I'd say then... "Karma is a bitch" 

Not to collect everyones addresses they are allready in the public blockchain, only identify KNCs

I think it's a wise attempt to atleast be proactive incase they decide to embezzle funds.
1- They are no longer trustworthy
2- They are a company with 1000s of people/customers, so a payout from knc wallet still keeps the anonymity of the people safe.
3- They have started up several different companies on the side and if no one keep taps on the blockchain it will be super easy for them to funnel 10s of million usd away and declare bankruptcy. Not even the government or the law will know what to do.
4- There is nothing that proves that they are not allready embezzling using personal wallets to mine to at "our" DC up north.
5- They built DC with pre-orders money.
6- They are mining more than the 5% that's a breach of contract. Which lowered all miners profits by atleast 10%. Then they pay (after a month or so) refunds with btc that preorders DC allowed them to mine. Basicly raping their so called loyal customers in the ass more than once.
7- Perhaps this helps to find out truly how powerfull the preorder DC really is.
And the list goes on

Summery: probably wise to keep taps on them, and all customers will continue to be as anon as ever.

This thread is currently so spread out that I would prefer further conversation regarding this survey and address collection at a forum dedicated to KNC( http://www.hackmyminer.com/forum/index.php?forum=7)

Question ("From what address did you receive your refund?")

At the current BTC price each $13200 refund is close to 30 coins (29 something). Even if they mine 15% of All mining activity, it is 540-620 coins a day (since difficulty is increasing at ~15%). They will probably not use more than 50% of daily revenue for refunds, I assume, which makes 270-310 coins available. This is comparable with the size of account from which i got the refund (however, I don't think that it is appropriate to share account numbers because you will give out your privacy as well). However, it also means that they will refund ONLY 10-12 machines a day. If someone has 2, then only 6 such people daily.
