Either you have been playing with something other than an 86x0,
or the 86x0 you played with was very different from all I've seen.

I've run an 8650 on 3x16A, worked just fine. My guess is that it draws
around 8-10A/phase.

And the fans (two of them) are mounted more or less at the top,
on the back side. Huge monsters that virtually blow things away.
