Anyone tried running one of these beasts off 2 PSU's ... aka 1 for each board?
Not sure whether I am seeing correct numbers so I'll cross-check with anyone who has (or has not for that matter).

Running 1 S5 with 2 Dell 550W server PSU's ..... I took this snapshot an hour ago, but the errors have crept up to 25 (0.0008%)

EDIT: And I am running this with just an S3 fan in pull .... seems like the stock fan arrived dead!

I am not running a 2 PSU setup. But I have lots of HW errors even if I underclock the S5. I am running now with 0.02% error rate default speed. I am using a 730W Xilence PSU with 56A on the 12V rail. Could HW errors occur more often if the S5 has problems with the PSU?

EDIT: I have not seen more than 41 degrees celsius on the blades due to winter time...

It might. I've never heard of that brand of PSU. Is it 80 plus? Bronze or gold rated? Can you measure the watts at the wall. You may be cutting it close with that one, if it's not very efficient.

Edit: I have had issues running miners in too cold of an environment in the past. It could be the cold, but I still suspect the PSU.

Xilence (http://www.xilence.de/en/home.html) is a german/chinese company. The PSU is 80 plus certified. It was tested for efficiency and reached 82%. Under full load the 12V rail had 11.85V. Peak power output before it shuts down was tested at 900W combined power. Based on that data I thought it should do the job. Sadly I can not measure the power consumption at the wall.
