any one know of a good at home way to test how many cfm a fan puts out? i found an ac fan in some old equipment i junked, i think its a 120 mm, thing feels like it puts out a lot of air, and its very very quiet. i want to know if it really does put out a significant amount of air. i thought of getting a big trash bag that says how man cfm it is, but that probly would give scewed results when the weight of the bag starts pushing air back toward the fan.
i went to the tomshardware forums and all i got was this lousy signature.
