First tent looking for advice on fans

I could really use some help with deciding which fans are best for my first tent set up.

It is a 1.2m x 1.2m x 2m with a 600W Dimmable Dual spec lamp. Also i should mention there will be about 1m acoustic ducting for each fan with minimal bends, and stealth is important.

To control everything and avoid any bumps in the road I'll be getting a SMS twin fan controller SMSCOM TWIN FAN TEMP SPEED CONTROLLER HYDROPONICS | eBay


But can not work out what will be the ideal size fans for my tent, considering i can adjust the speeds/temps as and when is needed with this gadget.

I don't want to go too small which is why I've picked the 6" as i know there's an issue with these with a loud humming noise when running a fan too low and want to avoid any loud of noises or smells.

Anyway I'm currently looking at this set up -

In - Ruck 150mm Low Power Version 470m3

Out - RUCK 150mm High Power Version 725m3

Carbon Filter - Rhino Pro 150/600

I know that an intake is meant to be a smaller than an out but here i will have control of speed + temps of both fans and the high power 6" has almost 2x the power of the low power 6" (which is basically made to be an intake fan).

Also the SMS controller is designed to adjust and work with 2 fans of the same size.

So what do you think guys would this be a sound set up? if not which fans would you make bigger/smaller?

ive had the sms mate yes theres a little hum buz noise but nothing too loud.in a tent you can go passive intake that 6L will create good neg pressure eneyway. r you using cool tube? or air cooled hood? the dimmable ballast is best piece of kit i invested in esp in summer months. get a cupple decent escolating fans for air movement n ya r away mate good luck. one last thing ya gonna have lots of kit in that tent if you carnt put em outside use bungee cords for noise check also ya could box fan off n foam it for a loss less noise.

150 cfm (4") vortex or can fan ( you cann go with cap inline fan it is cheaper) for tent ventilation. And 450cfm inline fan for reflector cooling ....
