Is 240 CFM enough to cool a 600W Sun Systems 6" Yield Master?

Arriving Tuesday.

Haven't used an air cooled hood before.

Will my extracor fan be enough?

Maybe? I would get a 440 cfm for a 600w.

Bigger is always better, but if you are using a tent and keep the room where the tent is in at around 64F to 68F and you are pulling air from that room through the hood and exhausting it to the outside, then a cheap 240CFM inline fan will work just fine!

It depends on your climate.
If your incoming air is close to the temp you want then it takes a lot more cfm than it does if you live somewhere cold.
You should always work on worse case, ie summer temps..

Thanks all.

Figured out how to solve all my issues.

Have a fan that is 4200 CFM. Going to fabricate a collector and split it to run intake on veg tent, flower room and the light...
Air fed from room next door. In a basement with window so should be good...
And yes I live in the North so cold air is no problem.
Should a thought of this a week ago...

You might look into a variac to speed control that bad boy.

Got one 2 days ago to control fan for tent.

Me thinks this is a better use for it

Going to put dampers on ends too to be able to control individual flow to each line.

IMO, even if you only need 240 cfm of movement, it's better to run a 440 cfm (or higher) with a speed controller, so that it only pulls the 240 cfm you need. The reason is because it will be running at lower RPMs and therefore be much less noisy.

Yeah that's pretty much what he is doing, but with a larger fan.

Larger.
Yeah...

1- 4200 CFM Fan with rheostat
1- Big ass thick box from work
= 1 badass airflow intake system for a 1,080 cu. ft. room...

Will probably end up with 6-8 lines running off it.

2-3" lines off it now are blowing like a Sthil leaf blower...
