Question
Wouldn't putting these fans in blowing
up help with the defrost. It seems that at OSH I was talking to a
360 guy that did this with great results. This is what I have been
planning on using instead of the defrost plenum that the legacy is design
with. Any thoughts?
Thanks

Addendum:
The bezels on our avionics boxes with this fan setup are cool to the
touch. I believe that it is best to blow air down from the glare shield
vents, rather than up. We don't notice any heat increase on our feet.
The fans noted below can also be had in 24 volts. I believe the mfg part
#
is 3324
Cheers,
John
