if anyone has fixed the random restarting please tell me I will pay a donation I have 3 restarting cubes and I have reasembled them all with no fix please help
I have also seen reports that a failing fan (not drawing enough power, I suppose) will cause random restarts - it's worth trying if you're out of other ideas.
You know, I bet your on to something. The Cubes might be restarting because they're over heating, it makes perfect sense. I've actually been considering flipping my fan around so that the draw is actually from the back; the purpose for this is simply to make it easier for me to properly position the cubes within a datacenter, and not get all tangled up with the power and network cables. Doing this, I might have to upgrade the fans... so I'm about to purchase these:
