I, too, thought it was fanless, but heard today at the expo that there is one fan, and it "expedites" air up through the "bottom" (though it can be used on its side) and "blows" out the vents that look more like radiant heat vents.

Didn't hear a fan going at the show, but then again, it isn't exactly quiet at Moscone.

And yes, remember the cube. Still my mom's #1 machine, alive and running with daily use. Couldn't switch her over to windows. Looks like she'll be "upgrading" to this one instead on Jan 22nd.

looking at the service manual now, I'm not so sure there is a fan. There is a funny "thermal pad", but I don't see an actual fan. hmm.
