If you guys paid attention to the Oc-Forums , the units have a flaw in the design. One of the screws makes contact with the circuit board , and because the screw connects a metal part to the casing, and the casing to the computer case, wich is connected to the ground... it can do some damage.

Here's a picture, mine had the same problem , but because i'm not using him right now , and it was never bolted to the pc case, i havent had any issues with escape currents. It was always on the outside of the midi case (only 3 slots), i think i got lucky

.

Althou there is a layer of lacquer , it seems that it isnt enough to avoid the contact.

Problem 2 :

As far as i know, a normal fan, when the voltage is reduced, the consumed current goes up due to the rotor trying to compensate the voltage drop. Thus, with an 1 amp fan, in low "burn" it can use almost the double of the standard current at 12v.

So lets say, 1 A per fan (a standard fan 0.5 A at 12v), at 7v, giving some margin, 8W. P=VxI . So 2 fans per channel, but not very powerfull fans .

If you stick 2x 1Amp (12v) fans in there, it barely holds up, or goes fireworky on you
