my cab is aprox 4 w x 2 d x 3 h aprox 24 cubed feet... i wanna know what type of fans would it need to ventalate that area properly....ive looked around and ive herd that you need a fan to ventalate your room once every 2-4 mins so i would need around 8 cfm... but that seems way low... would a 50 cfm fan work "well" for this size boX? i need it to cool the room off a decent amout.... also it needs to be quiet so any experiences you have will specific fans would be nice.... and anyone with a cooltube let me know
