Good...miners perform exactly as specified by BitMainTech...no surprise there...my first two C1's performed at spec as well. The version 2 wiring harness from Syscooling is much improved in that it plugs into one of the extra PCI-e connectors on top of the miner.
Bad...I'm not sure if I have a bad fan or if one of the connections in the new syscooling set up is bad. In the version 2 set up I received two fans use one 3-pin connector and the third fan uses another 3-pin connector; the fan uses a 4 pin connector. The version 2 harness connects to the miner via a PCI-e connector and has three 3-pin connectors and one 4-pin connector. This leaves one of the 3 pin connectors on the harness "open" which may not be the best plan. In any case, one of the two fans connected to the same 3-pin connector is not spinning...again, not sure if it is the fan or the harness, but something clearly wasn't tested (again) by syscooling.
Ugly...it took numerous emails, photos and posts to get syscooling to offer to replace one of my first two pumps which is leaking/non-functional. They said a day or two ago that they would "arrange shipping". To date, they have not contacted me with any sort of tracking number or other confirmation that they have actually mailed a replacement pump. One 1TH/s miner has now been down for a week. This coupled with the fact that I was also unlucky enough to receive one of the version 1 harnesses with a short which fried a fan header on one of my first C1s has left me with a very poor opinion of syscooling.com and I have to question BitMainTech's choice of partners.
I feel your pain. I was ignored and lied to and still have not received RMA unit's from syscooling.
Keep in mind you can contact your credit card provider. Funny how after I did they started communication again asking if I got RMA..... which they know from previous emails I have not. I know for me after almost a month I reached my limit of trying to get RMA parts.
