Will i be able to keep the buzzing down when using speed control? I spoke to S&P today and they said as long as you run the fans above 40% using the variable there will be no buzz. so at 40% of the numbers I metioned above do you feel i would be moving too much CFM for it not to be heard outside the room the closet resides in? Once the fans are placed in the top 1/3 of the right cabinet they will be covered with anything that will dampen the sounds. Unfortnately they I will have only 1 inch of space for some of the thinner areas of insulation. Any recommendations on the material to use. I heard those foam beds material works well and have and i have a older tempurpedic 6" pad i can tear into.
Any suggestions on how i mount the fans in the closet? can they just be placed on their side on a shelf that has a 3" foam pad on it?
Any suggestions would be gratly appeciated.
Well, the rest of your post gave me a headache. I really wasn't planning on reading the specs of a grow op. I also am not very good at visualizing something. I have to see it. So I can't help you there. Others on here for sure can.
As for using speed control, I havn't met anyone else on here that has tried using one. As far as I know I'm the only one, and I have failed at it miserably. The fan is MUCH quieter operating without the control than it ever could be with the control. I don't know why, but whenever I hook that control up it just buzzes like a hornets nest. Who knows. Still very quiet without the control on it. Plus, the fan has a High and Low settings on it already, so just go with those. As far as that 40% thing goes, I call bullshit. Anything less than 90% buzzed like crazy.
I ordered some insulated ducting (they don't have 5" at the hardware store), along with some dynamat material. Looks cool. Going to try it, hopefully it will reduce nearly all of the light rattling I have right now. I'll let you guys know how it works out.
And if anyone was interested, I attached 4" regular ducting to it, sealed it up a little, added a bit more weatherstripping for now and it's manageable. You can't hear it once the door is closed (from outside the room at least), but it would be loud enough to wake me up if it started up while I was sleeping in the room. Working on it though.
