I just got a new antminer s7 in and its acting weird. When i start it up its starts really silent and the fans are moving slow. there is a clicking noise from the fans. All the lights on the main board are on but no lights on the hash boards. A minute later the fans pick up speed and seems to be running normal. The hash board lights are on and everything. I checked the page and all hash boards are ok, no x's or dash's. The hash rate is very low though like 5 gh/s. Then like 3 mins later it just turns off and goes into the mode where the fans are super slow and are making a clicking noise. I've been using this psu with another antminer s7 and its been working fine. Can anyone tell me what the problem is?

Thanks

RE:One of the heatsinks isnt on took that board out now running with only 2 boards.

RE: The board status just updated and looks like i got two dead boards... JUST GREAT!

sorry to hear it, are the boards dead? could also be a distribution board issue (would explain the clicking as it keeps resetting) but with the heatsink being loose you dont really know what issue's that could have caused with shorts might be the reason the 2nd board died. if you can do much with it then tear it down take as many pictures as you can and we can offer as much advice as we can (the boards might be repairable or even fine if there problems somewhere else)
