hiya all i have a question regarding the cfm of this fan pictured, it came out of an old hp computer tower... i think lol the fan is 4 and 3/4 by 4 and 3/4 and no sticker on it anywhere. Is there a way to determine what the cfm is? or am i pretty much left with searching to see what i can find? thx famrers
