Fanless is the new it word. HP's Chromebox is being marketed as fanless when it's really not. Yep, a blatant lie.
We didn't cover it previously since, obviously, a 17W CPU can't be cooled passively in such a small chassis, but Lon Seidman just played with it and confirms the fan's noise.
Update: Picture from HP's own disassembly guide (PDF).
Update2: Still no word from HP. Also, hi reddit and hckr news ^_^
Update3: Five days and HP is still mum on the issue. Amazing.
Update4: Day six, HP quietly updates the Chromebox page...
