Reccommedations on a fan and temperature speed fan controller

[canadian1969]

Need to upgrade; the top port on my 27*27*63 tent (4.5 sq') is 8" , I guess about 23 cubic feet, way less if you take into account the light and pots etc.
In terms of CFM I am not really sure and I dont want to overkill it , but definitely need to go variable speed fan controller with temperature sensor as the ambient temps change often. And of course I dont want to break the bank.

Right now I am using a 120mm PC fan but its only good up to about a 100 watts of LED light

Canfans are legit

6in are around 360cfm

HyperFan, they come with remote dimming and run on half the electricity as most. My 8" is 75 watts and can move some air.

Those are nice fans, I dont have the budget for them unfortunately.

I was thinking of starting with this, then maybe getting a basic inline duct fan.

I need a situation where the fan runs all the time at variable speed to control the temp, not sure the best way to achieve it. Trying to keep it under $100

I think one of these actually

, and maybe a 4' duct fan like this?

Spend the extra on a plastic housing fan, and preferably one that is super silent, 20s to low 30s decibel.

Yeah, I am watching the decibels, what would you recommend for a small tent, I still need the controller, so have to buy that but what fan would you go with? Max the tent could handle would be 300 watts maybe. So maybe upwards of 150cfm? I'm guessing.

Titan controllers has nice equipment, not exactly cheap, but, as my father always said, you get what you pay for.

I thought your looking for a variable speed controller based on temperature.
not that one that turns on at set temp and off at set temp.
my understanding is he is looking for one that speeds up the fan as temps increase.
leaving the fan still running continuously for oder control.

Correct that is the ideal situation, I am surprised this has turned out to be so difficult. There are lots of cheap on/off temp controlled timers but not many variable. I cannot seem to source the Sentinel units up here in Canada and with exchange and shipping etc comes out to $195 CAD, which is just too much imho. I even emailed the company last week asking for info, Canadian distributors etc....crickets. I may just have to settle for a on/off temp switch. I am venting outside and this is primarily for odour control. In my research I have found that these variable ones can produce fan motor growl at low RPM, so it may not be as quiet as I had hoped, the on/off switching ones may be equally annoying. I may have to build my own controller lol. Probably $40 worth of stuff on Digikey would do it.

Another idea I had was this
https://www.amazon.com/Big-Horn-11603-6-Inch-Y-Adapter/dp/B003NE5A82/ref=sr_1_4
plus a couple 4" button fans 12v or 24v from Aliexpress , they are about $8 generally
and something like this

or this

Still using PC/muffin fans but I dont know if using a y adapter and two pc fans would actually double airflow, I know stacking fans doesn't work, but if this does work I would get my 150 cfm +-. 120mm PC fans are typically 75-80cfm
