Is the CPU fan wired as constant ON with avionics bus, or activated with panel switch?
Some -14 panel examples have a 'defrost fan' switch, some dont.
Doing some panel planning and wondering if a switch is needed.
Thanks.
Thanks for the replies. That's two votes for switch vs. constant ON. (where I was going)
But wait, aren't these fans also used for avionics cooling?
So you WOULD want them on for hot summer days, right?
(and defrost on cold winter days)
Am I missing?

This is my thinking also. I'm putting the fans on a dimmer pot (PWM) so i can control them for both purposes.
Thanks for all the posts.
After further review . . . . . , I am inclined to KISS this item and direct wire to the avionics master and have it constant ON.
Seems like there are more reasons to have the fan on and little reason to turn it off.
The ES-00056 fan is $9.55 on Vans so I am not too worried about wearing them out. Buy a few for the shelf and replace as needed.
Plus, simplifies the panel switch row.
Thanks again.
