Mike,
How is the fan noise on those mixers when running at idle (around a watt or less) levels?

The fan noise is unnoticeable for the most part.
FWIW: I put in a temporary PA (Yorkville M810-2 mixer plus speakers) in my church during the first week of July (it's still in there as of this writing - 3 months!) and it has been used for three services per weekend plus funerals and a confirmation.... It hasn't missed a beat.
The mixer is near the alter. There are several instances during a Catholic Mass where there is complete silence (no music has been allowed since Covid)... I haven't noticed the fan......and the sanctuary is quite "live".
btw: A new installed 70v system is going in this week. I had put a temporary rig in when the previously-installed 70v system gave-up-the-ghost after 20+ years.
