Insulated ducting off both ends of the fan works wonders on bringing noise down.
A fan that small isnt going to be very loud to start with as long as you get a decent one.

Im looking to get either the 4inch or 6inch fusion breath off growlights canada.
they're rated around 56dba maximum.
My big debate is if I get the 6inch, but drop it to say 30% speed (or less depending on plant needs) if it would result in a quieter fan.
Im also thinking about getting a duct silencer.

I wouldnt, you can easily find ones with nearly half the noise level. These are all cheaper and quieter and have free shipping.

Ive heard great things about this fan https://www.amazon.com/AC-Infinity-CLOUDLINE-T4-Thermostat/dp/B06ZXWN3BG?ref_=w_bl_hsx_s_hi_web_6796564011. Pricey but well worth it.

I'll take a look at them, do you find it comfortable to be in the same room as the fan?

Run a bigger fan with a bigger filter and a variac speed controller.
Box fans are quieter but the drop off with resistance is greater.
You can buy fans that are 23-28db , but most are between 40-50db, even my "silent airforce 2" runs at 48db.
You can box in most fans, using any box and something dense.
Acoustic ducting is worth the money.
If your not sleeping in the same room then you can do plenty to keep noise low.
The noise of air flow is easy to deal with, the noise of fan hum is not.

It's a totally different experience then those jet fans. I've been busy setting up a new room and as I was closing up the room a few nights ago...I had to touch the fan to feel for vibration to determine if it was on. The noise of the air turbulence at the exhaust exit point is noisier then the fan motor itself.

PS My experience has only been with the 240 cfm but I'm sure the 120 cfm is even quieter.

Can you vent out of the room? This is my setup and she purrs.

a duct muffler and a variable fan speed controller.. the combo should cut noise down by a good 75% or so..
