new SILENT exhaust fan! Which one? Please suggest!

nice! are these just as quiet? the T4 is overkill for a 2x2 or 2x4 so I was trying to figure out a cheaper option for my friend. This is definitely the right price!
I don’t have any AC infinity Cloudlines so I can’t compare it to those. I have various other brands of centrifugal fans.

I wouldn’t want it in my room on high that’s forsure, but between Low-Medium still moves plenty of air for my veg tent and is fairly quiet. Not much louder than my air pump or aero cloner. As with most fans, I would just upsize and lower the speed.
 
I have a 6” and 4” fusion breath inline for my 3x3. 4yrs old at least now. Still working great.
Turn them down.
I can run year round without ac. Temps are bang on.

I will be using the ac infinity fan to move air around the house. We have wood heat. Going to built a duct system to get heat moving better when it’s -40c
 
Pick a fan that's a little bit oversized and has specifications at least double of what you actually going to extracts. Then you can dim it down/use a controller to lower speed.

A big fan at low speed will make less noise than a small fan at maximum speed. You also got some headroom in the summer months when higher fan speed may be needed.
 
If you aren’t using a super long run of ducting or aren’t using a filter then a simple duct booster fan will work fine since your tent is so small.

I have a 2.5’x5’x6’ tent for veg that only uses ~300w of LED so it only needs minimal ventilation and the AC infinity RAXIAL S6 does the job fine.


This one looks cool to me, but I would prefer the 4 inches which is 22 dollar and 28 dB!

It looks perfect to me!!!! What's your thought? Can I use it as Main exhaust fan of my tent? Which as said is fairly small! Please confirm and I LL buy it!

Noise is driving me crazy

It pisses me off that I ve to spend 50 dollars (27 dollar of commission an postage) but it's seems Europe market is shit!
 
Im looking for you but it seems that if you buy this from europe they will charge you a arm and a leg for it
Ac infinity t4 inline fan from europe

Two hundred euro more... It's a mafia

But a big fan use lot of space of my small tiny tent! That's the downside, but it makes sense

A 6” or even 8” turned down will be quieter and move significantly more air.
 
and the AC infinity is also a beast other than dear! would not be too big for my tent?

I'm running a T6 in my 4x4 - it's more fan than I need in that tent but:

I usually run at setting (nearly silent) to 5 (really quiet); quietest fan in my tent by far.

If I notice the temps are too warm - I can run it up for a minute or two and watch the temps fall.
NOTE - my 4x4 sucks in HARD on settings 7-10. I did this a few times now
- once just to hear the fan on 10
a few times at 7 or 8 to drop temps fast ---- 85f to 79 in 3-5 min. (pulling cool air from outside)
