Dude,
PSU will die in a second. Do not do that and change PSU immediately
I also think that this is no good idea for the life of the PSU.
With this settings it has to deliver around 820-850 Wat I think...

fyi:
This is my Batch 2 Avalon with the factory PSU of 750w and 4 modules chip-frequenze with about 360!
Running stable since 12 hours.

While I'm at it, a word about the overclocking, based on what I've seen so far...
I'd suggest enabling --avalon-auto with a range of frequencies with --avalon-freq even if you're not overclocking, to allow cgminer to clock it down should you have an issue with heat.
For example, if you just want to run it at 300, add these to More Options:
--avalon-auto --avalon-freq 256-300
If you do want to overclock:
For batch 1 owners with the original PSU, I wouldn't suggest going over 325 or you'll risk your PSU failing:
--avalon-auto --avalon-freq 256-325
For batch 2 owners, there were a number of different PSUs, but even they can run into trouble so I'd suggest 345 as the upper limit to prevent instability:
--avalon-auto --avalon-freq 256-345
If you have upgraded your PSU to a good one >= 850W, then you can probably run --avalon-auto without a frequency range, and it may tune you up to around 365.

New Avalon firmware:
http://ck.kolivas.org/apps/cgminer/avalon/20130703/
Fixed one longstanding bug where it would occasionally fail to start yay. \o/
Should also prevent one mode of failure while it's running.

geez, you're amazing.
everyone here needs to step up and donate to this man.

Then you should be carefull with inverting the fans, normally pulling heat out of the case should not be as effective as blow it directly onto the heatsinks.
Therefore your temp-readings COULD be lower because the sensor maybe sitting to the now more cold site.
Only a thought, I also dont know where they are located, didn't even open the unit yet..

Did you change the location of the intake and outlet temperature sensors?
Your fan speed settings are based on those values...
No, I don't know where sensors located Your fan speed settings are based on those values...
time maybe the watchdog restarts the process if no hashing is done?
No, in my case cgminer won't hashing on previous firmware after change of settings or reboot, now it starts hashing immediately Fixed one longstanding bug where it would occasionally fail to start yay. \o/
Thanks, this firmware works for me, changed cgminer settings/chip frequencies several times and miner starts without problem Today tried flashing 07/02 firmware w/o keep settings flag and get not working cgminer, so bug fixed only in 07/03... at least for me
will try that too as soon as I am at home. I noticed also that it seems sometimes running but not hashing, but it fixed itself after a short time maybe the watchdog restarts the process if no hashing is done?

Nice thanks, maybe that fix my issue:
- my cgminer process seems to restart after every 4 hours or so.. must watch longer to see if it happens regulary. could it have something to do with the --avalon-auto, maybee the freq gets to high and it restarts? I am using --avalon-freq 300-340
One possibility. There are a few different ways that it restarts. One is an actual error in the code that makes it hang and stop submitting work, which should be fixed in this latest firmware. The other is multiple pool or network outages - and this is where the watchdog is trigger happy, as any period of 2+ minutes without work is enough for cgminer to stop being able to make work and the watchdog is not smart enough to detect what it is. Another is fpga screwups, but they are getting less likely with more fixes going into the cgminer direct USB code than they used to be with the old serial interface thereby bypassing one potential point of failure. An operating system error is also possible, and seems more common with the wifi enabled for reasons that aren't clear. Finally there's true hardware failure of one sort or another - overheat, inadequate power etc. - my cgminer process seems to restart after every 4 hours or so.. must watch longer to see if it happens regulary. could it have something to do with the --avalon-auto, maybee the freq gets to high and it restarts? I am using --avalon-freq 300-340

I inverted fans on my unit now they take out warm air from the box. (PSU removed)
Fan1/Fan2/Fan3/T1/T2/T3
Before: 1560 2520 2640 26 45 47 (temperature in my room 25C)
After: 1440 2160 2280 33 43 44

But thin fan now seems useless, vibration slightly increased fan and noise changed to lower frequencies
I think cooling in this way more effective
