Can anyone suggest a quiet inline fan? I don't mind paying a little more if it's quiet. I've tried everything from putting the fan into a box to insulating the room around it. Rite now I even have a blanket wrapped around it. Yes it does have a speed control relay. Any help is appreciated, thanks.....
 
Hey bdt, sorry but I can´t recommend a fan for you - hopefully someone else can come along for that.

What I can tell you is I reduced my fan noise significantly just by switching to insulated ducting. It really quietens down the "whooshing" noise as the air moves and maybe if you added a duct muffler as well it would have an even bigger impact.

You do not tell how strong fan you use.

Generally these work the best http://www.phreshfilter.com/products/phresh-duct-silencers.aspx

They kill a lot of sound, because the main part of noise comes from exhaust side. On the intake side you can use special duct with sound insulation, made with rock wool. Must be 1 meter long to be effective.

Many fans produce very annoying metalic sound on low rpm, so speed control does not always help. If your fan generates that sounds, you will hardly reduce them.
 
Using an over sized fan run at half speed is a good way to keep it quiet.

Make an accoustic box for it lined with various sound damping material such a hollow fibre,glass wool {take precaution wear a mask gloves and cover arms etc} There a fair few tutorials how to make an accoustic box for you fan.

I have a accoustic fan,which is temp controlled and have it in a DIY secondry accoustic box followed by a silencer and with accoustic ducting and have a exit point DIY muffler. You have to listen really hard to hear it , there is just the faintest noise but it is almost imperceptable.

Silencers are a great way to reduce the whooshing sound you get in the ducting.

Some quiet extraction fans you might consider

As stated before. Buy a 4" Vortex inline fan and plug into your relay and you will be happy. Do not buy a Ventech fan @ $60 as they are noisey junk.
Believe me as I own both.
 
Vortex is going to be one of your best quite fans, Can also makes a quite line.

Some tips if I may.

Insulated ducting helps.
Do not connect the fan directly to your carbon filter.
In the space of ducting between your fan and filter you can wrap carpet or foam to dampen sound. It's also good to do that for a few feet going out of your fan.
hang the fan with bungee cords or similar stretchy material.
I like to mount the bungee cords to a board with foam between it and the wall to further dampen vibrations.

Buy the best fan you can if noise is a consideration. Cheap fans make more noise.
 
I use the hydrofarm 6 inch and its silent. I use the air speed controller at about 15-20% to cool two 600 waters in sealed hoods. I love mine its been going Strong for a year+ now
