Asus for sure, with the Dell a close 2nd. The Acer is a PITA to open up and access the WP screw, ram, and SSD; otherwise it's about the same as the Dell in terms of fan noise (so slightly louder than the Asus, but much better than the HP)

My hp is barely audible, i gotta put my ear next to the case. Maybe they made a second revision or something.

Same here. My HP chromebox is near silent. Only thing i can think of at the moment is that its pretty cold at the moment locally, maybe it`ll be different in summer.
