Seems OK, although it shouldn't be that complicated, they are pretty easy things to get going. Was it a new or used Cube?

What fan was with the Cube when you bought it? The fan can affect the miner if it is faulty, but if it's rated correctly & working fine it should be OK. The fan in my cube is upgraded to a Scythe Gentle Typhoon, that is a 1850rpm fan, but it is much quieter and moves more air than the rubbish stock fan. I tried a Corsair Air Series SP120 High Performance Edition (2350 rpm) fan in my cube, but then it would not power on, the relay just kept clicking and resetting the cube over and over in a loop. The Typhoon draws a current of 0.083A, while I note the Corsair draws 0.18A, so maybe if the fan is drawing too much current or not enough is the problem with the fan, maybe check yours?

Also, when you say the fan needs to be blowing out of the cube, do you mean you reversed your fan so that it is essentially sucking air across the blades and through the cube, or is it blowing into the cube across the blades? As you look at the rear of the Cube with the LED's, fuse, power ports etc, the fan should be blowing inwards, although I guess it won't make much difference as in theory it should be moving the same volume of air over the heat sinks.

What PSU are you using, the power supply can be a cause of a lot of problems with Cubes too.


Everything else seems sine, although I would advise against keeping bit coins in an online wallet. Much better to send them to one on your computer such as the official Bitcoin-Qt, which you can then back up regularly to another location or paper etc.
