Okay. I found this. I believe it should show up as 1.2.14e Version 14d and earlier reported as 1.0.0

Sorry ahead of time for the low quality images.  Also, I figure everyone is already past this step at this point in the game... but I'd post it anyway.

Originally, I was going to use the ARCTIC Accelero Mono Plus VGA Coolers and grab some PCI brackets, but that setup was considerably more expensive and proved to show lower hashing results as posted by others.

Then, I was going to do the double Antec Shelf idea like MrTeal. I ordered 8 coolers for 4 boards, but I tried it with a single one and I am fine with the results... so now I am going to buy 4x more boards to use up my 4 extra Shelfs.

So to mount the single shelf to the Chili, I mounted it directly to the board with the provided 1156 back plates.  I mounted the top mount to the heatsink as it was directed in the instructions (to the underside of the heatsink).  I then used misc computer screws which threaded into the back plates... I have a ton of screws laying around from buying internal computer devices (CDROM, floppy, etc drives) and they provided a very tight connection.  The board doesn't look like it's bowing at all.  I used nothing besides a rice sized amount of the Antec included thermal grease on each chip (maybe too much but it seemed to work).  I didn't really think about standoffs, since I have them mostly sitting in their sides like the first picture showing the back plates.  If you wanted to sit them upright, they sit on the back plates.  It's probably not 100% safe (something could short the power solder points underneath), but oh well. It works for me.

I tried one Chili with a thermal pad, but that one got 27 Ghs.  I redid it the way I did the others and it raised up the Ghs to around 34 or so.

All in all, I'm getting between 34 and 36 ghs.

Well its just 6x chilis arranged.... so ... same thing applys bout if the 212 heatsinks are good or not on chilis and if mine peon can control them =)

I updated the firmware. I confirmed 4 outer and 4 inner leds are blinking in turn. After power cycling, when I check the firmware version, it is still 1.0.0. What's the problem?

Ah, a little searching found it. I've never heard of a Sunzi x6 before.
You'll have to ask CrazyGuy about it.

yes, it looks really nice, if an rpi could control it...would be awesome!
Im asked about the HSF's ... because of choosing between the rack version or the "open air" version w/ blue fans.... didnt know which cooling would be better.

Cool, well reason Im asking is ... Im considering the sunzi x6 miner.... would be awesome if could get it to run on my rpi.

I'm not sure on that one, I've never tried MinePeon. As for powered vs unpowered hubs, it shouldn't make a whole lot of difference. The board generates 5V internally and the 5V line from the hub is not connected, so there won't be any 5V power draw there.

I would use a Hyper 212 Evo if you're not looking to mount them using a bracket. You just get more cooler for your money that way. For VRM heatsinks, I just bought some off eBay from China, but they took a month to arrive. When I was testing I just ordered a pair of these per board from Digikey, they work great.

Can these be ran using minepeon w/ latest builds of bfgminer? ... Well can an rpi power 6 of these things w/ a powered hub?

Also, if given the choice would the accelero GPU cooler or hyper 212 cooler work best on these?
Im guessing w/ the hyper 212 .. mosfet cooling would probably needed... is there a place to buy heatsinks for the fets or another easy way to cool them?

Hah, I had the exact opposite issue. I would have so many issues with Linux and when I put my (Currently 34) Chilis on Windows 7 64x I had much less issues if any.

The Hubs seems to get hung up sometimes and I noticed that usually if you have no USB Errors (Device Manager) there won't be any HW Errors. Occasionally for whatever reason windows doesn't like the chili plugged into a particular slot on a hub and I have to just move it and the Chili is seen fine. All this has to be done prior to starting the mining program.

Once you have them running though it's smooth sailing

I've tried them on a powered hub, connected straight to mobo USB and now connected to expansion USB.

I'm hoping that the firmware is/was the issue. The guys I bought these from said they mine via linux and they have been spot on in that OS. I could understand Win7 going whacky with these things.

Might be totally off on this but do you have them on unpowered USB hubs?

If you are getting nothing but HW Errors it is likely due to your USB Hub/Or you started the mining program while the Miners were still booting up.

Occasionally I'll have one that just causes issues out of the group (never all of them) and a quick reboot and changing the port the USB is plugged into fixes it.
