Re: ATM multiple cooling fans? (newbie)

["Alan Garcia" <ngarcia@columbus.rr.com>]

I agree!

I have added 2 cooling fans blowing on the face of my full thickness primary
and one large blowing on the rear, for a total of 130 cfm.  The results have
been dramatic.  I couldn't be more pleased with my scopes imaging.  I wish
I'd done it 3 years ago.  Remember it is important to prevent vibrations, so
be sure to take adequate vibration dampening in to consideration.  IMO heat
is a vampire.  Be aggressive!
