    For anyone looking at these, I just got mine in today… Worked perfectly running 4.5 @ 650mhz. I even cranked it up to the factory default of 700mhz and it is running 4.7+. Your milage may very, I have had S7s that top out at 4.5 @700 which is what I thought I would get, but very pleased with the results! As always customer service is great!

    I ordered this 650mhz unit 2/16/18 and got it 2/23/18. So from one coast to the other in 7 days. The unit is very clean. (Thank you ParallelMiner for that!) I am powering mine with one DPS-1200 on two hash boards and a DPS-750 on one hash board and the control board. The unit booted right up and is running about 4.2 – 4.3 @ 650mhz. I set the fan to 70% and seeing temps of 65c which is too high. The unit is definately louder than my old S5. The first intake fan is making a lot of noise intermittently like the bearing is going and will probably need to be replaced. Other than that running well!

      Hi, the S5 come stock with only one fan, here you have two. We do install new fan with each unit but it is always possible to have a failure. We would be happy to send you a fan replacement at zero cost. Please log into your account, see your orders and request an RMA for a fan replacement. Mention to comment post here and my self. I will make sure you get that fan replacement within 3 days

      Although this would be terrible … Just make sure the install fan are not position is such way they cancelled each other out! Flow of air intake should go from in to out. I have seen staff installing fan the wrong side … Killing the airflow, increasing noise and temps. Just checking all possibility.
