In this unit it's only running two. One in control center on top to keep heat down, other in bottom of wineador blowing air up back wall.
Interesting…I would love to see detailed photos of how you have it wired. Do you have the Sentry 2/3 built into the front side of a desktop? I've seen a LOT of pics of Wineador build outs and yours is by far the most intriguing that i've seen thus far.
