315 CMH heat management

I have a point and read thermometer. My canopy height is around 73 and the other thing i used showed 80.

Extraction fans are simple. Carbon scrubber in tent with a 4 inch duct going to your exhaust fan out of the tent (if you have the room) and a fan controller. I use a veriac transformer to dial it in just right but a regular controller will get you started cheaper.

The veriac removes the fan howl caused by the cheap controller which uses voltage interruption to work. A veriac transformer changes the voltage going in.

I run 2 tents totalling 10 square feet with a 4 inch fan at 50% currently. 73 degrees canopy height in both tents (one fan with a T pipe pulling 2 carbon scrubbers)

Your scrubber will decrease your tent humidity when compared to ambient air by about 3 to 6%. It matters if you cant get it past 30. The girls tend to suffer.

Well yeah, i can only have so much exhaust before it sounds like a rocket ship from my spare room.

but still regardless, tried higher cfm still issues, had to get an air cooled hood to control the temps.

Higher CFM doesn't make things any cooler. If it did we'd all just run big fans,

Im interested in the Sunplix 315 CMH, but I'm concerned about heat. Anyone have any experience with heat management with one of these. I usually grow in a closet that's about 4' long by 2 1/2' deep by 8' tall, but thinking about using a 4.3' x 3' x 6 1/2' tent. These are expensive and I don't want to waste money because I can't manage the heat.

I just bought a new fan, I have owned lots of fans all worked great but none were particularly quiet, even the silenced fan I had ran at 50db. My new one is 25db, literally can only just hear it in the room and cant hear it anywhere past the door.
Which is nice because im always looking for quiet and have super sensitive hearing. Wish I had bought this years ago TBH but I bought a very expensive fan previous and stuck with it for many years due to the cost.

If your ever in the market for truly quiet fan that can still shift air I can give you a link. Im English though but im sure they are made in china so could probably be sourced in other parts of the world.

BTW its highly likely from your first post that your fan doesn't have much pressure rating. Because you shouldn't be getting such a rise from ambient with that cfm.

Hey dude, awesome stuff sounds appealing. Im sorta in the same boat! a link would be much appreciated for sure.

got my temps to 25degrees with a aircooled hood and a 315cfm hyperfan + 315 cfm filter. noisy bugger though
