The best option is to get two fans, one pulls air in from the bottom, the second pushes air out through the top - or from side to side, across the equipment. If you are going to get the 110 fans I would consider the rheostat idea to slow them down (noise), or wire them in series which would cut their speed in half.
Cooling fans for tube amp
Just read a thread from 2005 about rack cooling fans. I'm having a custom built wood cabinet made with casters for my stack that includes an Audio Research D-90 that can get very warm after an hour or so.
Any new recommendations on what fan to use and how to set-up? Most computer fans don't have standard wall plug connectors.
I was thinking about a 4" diameter fan that will plug into my "Switched" power output off the SP-12 pre amp so it goes on auto whenever I power up. Should it "push" or "pull" the air? Mount on the back of the cabinet with a cut-out for airflow?
I may just run a power strip off the pre-amp's switched output to power one to two fans plus the subwoofer so they all only run when I power up the pre-amp and amp.
Also thinking of putting heat resistant tape/insulation on the underside of the wooden shelf directly above the amp.
Sound OK?
Or something better work w/o a major engineering project?
