Venitalltion Help....New 3x3 Grow Cab with 250W HPS/MH

Currently in the process of building my new 3ft x 3ft x 4.5ft(tall) grow cab.

This will be my second grow and I've learned a lot from the first one, but now its time to do things right.

I already have a 250W HPS/MH setup with a 6" Cool Tube and reflector.

I'm trying to figure out which fan to get to cool the light and ventilate and odor scrub the cab.

Noise is very important with my situation so I will need something quiet.

Since it is only a 250W and my box is only 40.5 cu ft, I was thinking of going with something like the 4" Sunleaves WindTunnel.

I've never used a carbon filter or HPS light before so this is all new to me and I can only go off of what I've read online.

Preferably everything will be contained in the box (fan, carbon filter) and my intake will be in the floor, exhaust out the highest part of the side.

Given the size of my cab I don't think I need much as far as CFM's for CO2 replenishment of the plants, I'm more concerned with making sure I give adequate cooling to the light and keep noise to a minimum.

I have only heard good reviews of the WindTunnel as well as the 4" from Hydrofarm, but though I'd give the specifics of my grow and see what you guys had to say.

Let me know what you think.

Use a 4" fan and filter combo. Get a good one, can or phresh are good. I have used both. To keep the noise in check use a fan speed controler to slow down the fan.

Ok, thanks. If I go with the Wind Tunnel (200 CFM) what CFM filter should I be looking for?

Also, what is the best order of things? I will only need things in a straight line across the top of my box, so very easy with no bends and short ductwork.

Filter -> Duct -> Cool Tube -> Duct -> Fan -> Duct -> Exhaust

To reduce noise more, hang your fan,filter etc from rubber bungee cords; a lot of noise is vibration

(Filter-fan-duct-tubes-exhaust......for me anyway. I didn't want hot air running through my fan.)
