In Behringer terminology the device has 18 mixing channels, 18 analog
inputs, 18 USB returns and 18 USB outputs. The "channels that are sent from
the host computer to the device" are the "USB returns".
You can route any of the analog inputs or USB returns to any mixing
channel(*). In the other direction, you can route a multitude of sources
(channels, busses, FX L/R, FX Sends, Main L/R) with a lot of tap points
(Pre EQ, Post EQ, Pre Fader etc.) to any of the USB outputs ("those
channels that are sent to the host computer").
Does the device have a fan?
No, it doesn't.
Channel 17/18, aka "Aux", is special as it is stereo linked and reserved
for the stereo Line in (17/18) as analog input. you can not route other
analog inputs to this mixing channel. You can still route any USB Return to
the Aux channel.
