My canopy is a fully enclosed 60"x18"x16" so is about 11 cubic feet of air space. The two Vantec Stealth fans are rated at 53 CFM each so I get 10 complete air changes pre minute at only 28 dBa which is more than sufficient for my MH lights. The Stealths are $14 apiece at Newegg.com and the variable voltage DC power supply which is large enough to power up to 4 fans was $5 at Harbor Freight but anbe found at Wal Mart, Radio Shack, Frys electronics or any electronics vendor for less than $10-$15. So $45 or less including shipping and tax for two variable speed 4" fans complete and much quieter.
