What size attic fans CFM wise?
i use six attic fans for 200 gpu , my neighbor are closer than urs but my garage
is detached
1500 cfm each , they use around 260 watts each
noemaly i only ever have 4 on but with comininf spring
ive had to turn all six on which is not ideal. Next few weeks
ill add ain intake fan 2500 cfm , to bring in outside air , that way the
total air in the garage gets exchanged faster ,
it should reall help impove tempa even further
