RE: [APD] RE: CF retrofit suggestions

["S. Hieber" <shieber at yahoo_com>]

Sometimes gravity flow convection is not adequate for a
specific installation due to the reasons you mention or the
amount of heat that needs to be disappated, room temps and
the abitliyt of gravity flow to deal with the heat. . . 

Vents are quieter, much more energy efficient than fans.
But fans can be much more effective in some cases.
