Fan speed controller.
Insulated box around fan.
Insulated ducting.

Duct silencer (if needed) at end of duct run.

buy a cooler and cut holes.my fan is easily half as loud before installing in a coleman cooler.then you need a muffler for the sound of the air flowing.should be able to find diy links here for both!good luck.use insulated duct too!

I installed a fan speed controller on my fan, and it still runs loud. I guess you need to attach the fan itself with some type of solution. That cooler idea may indeed work.

I used a rubbermaid container lined with dynamat. It's much quieter with just the controller turned to 90% outside of the box so there are no extra bends.
Eliminate any bend, corners and/or sagging in the duct run. Mufflers work great if you hear rushing turbulent air.
I've also noticed that wrapping the ducts near bends helps reduce vibration noise.
My vortex 6" is a lot quieter than my windtunnel 6" or maxfan 8"

Also hang fan or box with fan inside with bungee cord. It will keep fan noise from tranferring to hard surface which is louder.

I just tell it to shut up!

Lol

All those ideas work. I was lazy one day and put my shirt over my fan. It worked fine

Goodluck to you

I've done it all.. noise sensitive and just plain don't like noise..

best tips as follows:

-speed controller.. but you will get a high pitch sound, but worth it over the raw noise
-duct mufflers.. very under-looked. not sure why but they work very very good. even one is better then nothing if you can't afford 2.
-box for the fan.. this can be anything from cardboard to wood with sound insulation. I've looked into finding a box for a fan, but never have come up with anything to just straight purchase to slip the fan into.. maybe someone knows though.. I couldn't find anything.


another tip is to size the fan correct, do not buy a bigger fan then needed. also fans are a big consumer of electric..


have fun in sorting out the noise issue..

I somewhat disagree with this. If a speed controlled 6", after turning it down, is all you need, thats cool. If you run a 6" at full power, its alot louder than running an 8" and turning it down.
My 6" exhaust run is at the top of my tent and has to bend to get out. I ran an 8"-6" reducer into an 8" 90 degree L(had to be sealed air tight) to reduce added turbulence.
The light duct also had to be bent so that sunlight didnt leak in. Now that I also use an 8" Y, I use backdraft dampeners. It's an 8" and I used an 8" 90 degree L angle for its bend also.
I think it should also be mentioned that some fans dont like certain speed controllers, they actually make a much louder sound.

Using oversized ducting is always helpful-although not always an option where space is at a premium..
