it was the FAN sensor!
although running like a freight train, the single fan shipped with my new S7 had a bad sensor so showed null fan speed, which apparently kept cgminer from hashing.
swapped in an old s3 fan and under clocked a bunch to maintain temps and she is happily hashing away.
450Mhz getting a hair over 3TH/s from most recent batch.
does anyone think bitrmain will somehow compensate me if i send in the old fan? aside from sending me a replacement?
i ordered a bunch of parts for some trial and error troubleshooting on my own accord, but i am really only concerned with the two weeks of mining i missed out on.

Has anyone purchased and received the new ANTMINER S7 BATCH 16 with One Fan? If so, let us know the stats on this machine, especially temps.
I have found that the batch 12 run about 10 degrees calculus hotter than previous models. Does anyone else see this same condition?
Yesterday i purchased a Batch16 S7 with a second FAN thanks to your coupon

As sson as i get it, i'll post the performance with SINGLEFAN usage and DUALFAN usage
