Kevin,
Assuming this amp does not have a fan, and it's still available, I'll take it!
Larry is right... it has two fans. These are pro-audio amplifiers designed to be rack-mounted and used under harsh conditions. Part of that requires active cooling for the way they are designed to be used. Most of them I sell, get used in home theater installs where the amplifiers are remote mounted in an equipment rack/room. They are not installed in the listening area.
How loud is the fan? It varies, unit to unit. My F1200-TS is not silent, but it isn't obtrusive by any means. In a HT install it adds about the same amount of background noise as my old projector, which was also actively cooled.
