250W HPS -- Lighthouse Tent (3x1.7x5) -- NEED HELP WITH VENTING

Basically I need to figure out the QUIETEST, cheapest, easiest way to vent the heat out of this tent. If anyone is selling a 6in inline fan, or insulated ducting, or have links / ideas I'd love to hear them. It being quiet is the number one issue for me. thanks RIU.

Moving air makes noise, no way around that. If you have ever been in a data center you know what I mean.

I understand there is no way for it to be silent.....but there are some fans that are quieter than others as well as different techniques to dampen said sound. I've never had to really deal with using anything other than PC fans for some small box grows so before I pull the trigger on a fan and some ducting I want peoples inputs on what brand /combo has had success.

Also any tips for soundproofing a room, tent, etc?

Have you ever looked into the Panasonic Whisperline fans? I've read they are the quietest and I've been thinking of putting one on my mother/clone tent.

Here is where I found info on it.

Encomium -- !!! No i haven,t heard of them, but you are a lifesaver. this is EXACTLY what I'm looking for +rep
