So far the burn-in seems to be going very well!
Has anyone mounted some fans in the back to suck the air out? Or maybe thought about cutting some holes and mounting fans on the top cover?
Thanks for opening this thread.
However, judging from the low SNR of the main KnC thread I would suggest to close this thread and restart it as a self-moderated one before it is discovered by the trolls and people that post their ROI calculations for the 100th time, etc.

For those of you who are upgrading the case fans (maybe even going with 120mm fan with an adaptor), what fans are you planning on using?
Yours was the post that prompted me, my room temp is only 23 and with my aircon set to 25 it's never coming on. Initially I thought this was good but the amount of air coming out of the back is quite low so slightly concerned that all the heat is staying in the box.
Look forward to hearing how new fans affect yours.

Thought it might be handy to have a seperate thread where owners can share information, tips, modifications, improvements, addons etc away from the clutter of the 'where's my order' posts in the main thread.
That sounds like a good idea. I have posted my experience and will keep it updated over the next few days.

If I see common questions cropping up will add them here as an FAQ reference.

FAQ
Q: How do I login to view cgminer working.
A: First ensure you have enabled SSH from the web interface. Next use a program (eg PuTTy http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html). Connect to your miners IP, login:root password:admin then from the command prompt type 'screen -r'. When you are finished press Ctrl + A, D to detach.
Q: My miner settings page is blank and won't load
A: If you make any changes to the pools through cgminer for example adding a second backup pool, then it throws this page off as it's expecting to read only 1 pool. As long as you are mining this can be ignored, hopefully in the future the web interface will allow multiple pools.
Q: What are these errors "KnC: accepted by FPGA 21 works, but only 0 submitted"
A: These are not usually errors (*). They occur when a new block is found. Rather than submitting stale work which will be rejected the machine is getting rid of existing work and loading up new work, this is why there is a pause and hashrate drop as it slowly gets back up to speed. * If you see these messages one after the other when no new block has been found then that does indicate a problem
Q: I've updated my firmware but it's still showing the old version number
A: The page has been cached, try F5 or Ctrl+F5 that usually fixes it.
Q: What's the deal with the Corsair HX850, is it safe to use or not
A: It's still early days with the investigation that KNC are conducting. Some miners where caps have blown have used this particular model. The problem is thought to occur when the a safety mechanism in the PSU shuts it down, when it is powered back on it is delivering too much current. It doesn't appear to be a problem during normal on/off usage only after the PSU has shut itself down. If you already have this PSU and decide not to change, I would suggest that if you find your machine has shut itself down follow these steps. 1. Disconnect Power. 2. Remove all PCI-E cables. 3. Reconnect power and start with just beaglebone. 4. Run for a couple of minutes. 5. Shutdown 6. Disconnect power 7. Reconnect PCI-E cables 8. Reconnect Power & Restart.
Modifications
Fixing the time.
Machines appear to ship with the time set to UTC, although it's not important it did annoy me not having the correct time, these instructions came from Nanners on the IRC channel and worked for me, replace 'tigggger' with whatever you want. Note these changes will probably be lost when you reboot, so might require you to repeat step 5 onwards.
Addons
uski has created a great little addon to show more information about your miner, like which cores are enabled/disabled, vrm voltages etc. As this firmware is software based KNC have confirmed that it does not invalidate your warranty.

1. cd /config
2. mkdir tigggger
3. cd /config/tigggger
4. wget http://www.angstrom-distribution.org/feeds/v2012.12/ipk/eglibc/all/tzdata_2012d-r3.0_all.ipk
5. opkg install /config/tigggger/tzdata_2012d-r3.0_all.ipk
6. rm /etc/localtime (NOTE this gave an error for me as the directory wasn't there, but not important just carry on)
7. ln -s /usr/share/zoneinfo/YOURTIMEZONE /etc/localtime (In my case it was ln -s /usr/share/zoneinfo/Europe/London /etc/localtime)
8. cd /
9. /etc/init.d/ntpd reload
10. ntpdate -b -u pool.ntp.org
Now if you look at cgminer the time should be correct.
