And on the KNC forum, some industiral design professor got his students to test the airflow of the case design. His thoughts: "I just put a team on this new setup and ran tests it looks like it has 3 high pressure areas that disrupt airflow so far it looks lie you will need to use 3 fans in the front mount the controller on end and move the two ASIC closer to the front. this will allow more cool air in and give a bit longer run for the airflow channel to minimize the high presser buildup (any high presser = hot spots )" http://forum.kncminer.com/forum/main-category/hardware/590-case-revisionIs anyone interested in or planning in building their own case, where the airflow is optimised? I guess the above is a good start

nah, just to the select few who are actually pointing.
As to the angled fins, i'm trying to figure out if this was the design all along, or if it was a late modification.
When they posted their "box with fans" photos a couple of weeks ago, some people complained about the bad airflow (i.e. exhaust from fans blowing into inlet of others). So I guess they went "Oh yeah, we didn't see that. Now how do we fix the problem without having to junk the 4000 metal boxes we have stacked up in the next room?" Tada! Weld a piece of metal in to divert the exhaust. Seeing as it wasn't in the box with fans photo, you can be sure it's a late modification. It's a bit sad they couldn't see the issue themselves, considering how every second news update contains the word "engineers" and "engineering" and how they are not much good at anything other than engineering. So, if everything about KNC bothers you so much, WHY ARE YOU EVEN POSTING IN THIS THREAD?Have a wank my friend, you seem a bit wound up.

This thread is a total joke - you have finger pointers, speculators, trolls(negative speculators), and those who actually want to share information. To be called a fanboy would be a fallacy because there are no physical products yet to become a Fan over - hence there are only optimistic speculators. If I read correctly earlier on, day one orders are expected to in the next 10-15 days right?
Even the most optimistic speculators do not believe they receive unit in two weeks. I believe they hope the unit will be delivered early next month, saying no chip or prototype will be shown before KNC ship

Keith from KNC says: There has been a slight revision in our casing that we had neglected to previously explain.
The case has had an airflow improvement to ensure increased thermal efficiency.
We have ensured the hot air from the front two heatsinks is redirected, avoiding the rear chips, and is expelled from the casing by installing fins affixed to the upper casing section (despite appearing in the CAD as part of the lower section of casing). In turn this allows a sufficient amount of cool air exits to ensure a cooler operating environment for the rear heatsinks to operate comfortably. What I don't understand is why they didn't make a wider case with all four modules side by side instead of trying to direct the air with baffles. They wanted it to be rack mountable for data centers. Racks are typically 19" wide. It's not 19" wide, and not rackable. Further, the PS is external and has to live next to the case. Awful solution from every perspective.

You can still put it on a shelf in a rack though but if they put all 4 boards next to each other, you wouldn't be able to.

Yes. Actually it is. Since it's the truth.
I quote: Who is going to read >400 pages and the search function of this site sucks.
I read them. All of them. And I am able to use the search function properly.
Congratulations! I guess that achievement gives you the right to belittle anyone else that comes along with a question. Nope, but it gives me the right to point out the information you wanted in a short and effective way and critize your lack of ability to get them yourself. Seriously, if you feel emotional hurt over my comment - just don't post questions like that. I am generally in favor of questions. Every one has them, you know? But most people try to get the answers themself first before spamming a 400+ pages thread with them. If your question would have been: Hey does anyone know if Upgrades are possible for November orders? - I would have given the same answer in the same tone as bitcoinorama. But not to a "hey guys, I am too lazy to look for the answer myself for 5 minutes" post! It wasn't my question. Go back and look. The question was mine. Sure like the ignore - mash it all the time. And I would have thought if I had happened across mention of how those modules are attached to the main board it would have registered. I still don't know. Reading 400+ pages on the chance an informed reader mentioned it seems less a good idea than asking.

The case is nowhere near 19" wide. They could have made the case 19" so it actually could be rackmounted and would have had enough space to mount a (user supplied) ATX PSU inside AND put the modules in a line.

I never said they were 19". You can put something in a rack that is less than 19" with a shelf but you can't put something in a rack that is over 19" wide which the case probably would have been if they put 4 boards next to each other.

I think the thing is ~16 inches wide, leaving just not enough room for a power supply on the side (remember, there's a nasty bundle of wires, PS fan exaust, and the shelves are a hair narrower than the rack (just trust me on that). So, the PS lives on top anyhowz.

Could be handy if we can , if even for a next gen module. I've read the whole thread and mentioned it a time or two but still nothing interesting. I figured I'd wait and look for myself since I'm not likely to be wanting to do that for a while

So, the PS lives on top anyhowz. Yeah, that sucks. Looks like most power supplies are 3.39" tall so you end up over by .14 inches if the case ends up being exactly 400mm wide. The power supply could still go in front of or behind the unit but of course, then you have issues with blowing hot air into the case or getting it from the case. Hopefully gen 2 will be better thought out.

""We will be releasing individual upgrade modules which you will fit into the device yourself. More information will be released on this in the coming weeks, most likely after shipping has started." Looks good, "coming weeks" rather than month also looks nice.

Don't expect civilized behavior from the bitcoin community. It's been ravaged by scams and greed. At least he answered your question. That's more than I would've expected.
