Yes, those are two fans on the rear picture in the other thread. If they are on all the time then it is amazing quiet! I hear nothing in the room.
While the Pansonic commercial plasma brochure is correct with their printed words, they play with some marketing trickery. Notice that the contrast ratio is boasted at 4000:1 but the astericks notes that this only applies to the SD models. Additonally, page 5 of the brochure touts "Fan-Less Quiet Operation," yet this applies to only the under 50in models. The notation immediately below states that the 65in and 50in models features a "noise-supressing silence design." Which we all know to be fans -- albeit extremely quiet ones.
