Just a bit more information on the Android and the Cube.  I found today if I brought my Android online (testing again) it did not affect the Cube but if I restarted the Cube it just died off within a minute of starting - kill Android and restart Cube and it was back to 31GHz in no time.  Hope this helps someone as this drove me nuts for several hours.

I had the same problem and of course had a couple of brand new fans laying here where I built out a case.  This morning I was mining at 30GHz and then about lunch went to nothing and then died - nothing.  Restarted several times, replaced fan 2x still run for a minute and then click off...  I thought I had fried it not sure how but was convinced until I read the little blurb about the Android phone on the wifi.  Well guess what today at lunch I was debugging an android app and brought an old Android phone online connected to wifi since it is not on the cellular network so I pulled the battery on it and within a few seconds was back to 30GHz - so my question is what the heck does Google and Android have against CryptoMining and BitCoins.....

Hope this helps someone in the future as this has drove me nuts for the past 6 hours hope to make that time back up and toss the Android in the garbage.
