Nope - those are booster fans. I have tried to use them before and they are really only made to help flow through ducting. By themselves , 2 of them did not generate enough flow to cool my dual 400W system - with cooltube
Tokudai Reviewed by Tokudai on . YO! will this fan work? -------------------------------------------------------------------------------- Im having trouble keeping my closet temprature below 80-85 degrees, so im looking for away to cool my 400 watt mh light without buying a cooltube. i found this cheap inline-fan on htgsupply.com for about $40 with a rated CFM of 240. ( High Tech Garden Supply ) would this work? Also, would i have to buy this ( High Tech Garden Supply ) to attach the ducting? also, does anyone kno where i can buy some 4" duct Rating: 5
