@Wile e Peyote am I correct in thinking you're running a phresh hyperfan stealth (silenced) dude?
Would love to hear your thoughts on it please mate. How quiet is it? Need an extractor and I'm in a flat surrounded by neighbours beside and below, with wooden floors and peanut butter walls. What sort of speed do you run yours at and is what size is your tent please man? Did I read somewhere you said it vibrates like a bastard? Does it still vibrate on bungees? Vibration is probably more of my enemy than noise.
Expensive fan for a man of your "geographical persuasion" isn't it?!
