Cooling my lights need advice.

I currently have a 4 inch 190 cfm inline blower pulling air through my carbon filter and puching it through my 400w air cooled hood. Soon i will be upgrading to 2 600w and the 400w i already have. the 600 watts are gonna be cool tubes. how many cfm would it take to cool all of the lights together? any help is very appreciated.

anyone? please help?

6 inch fan for sure. like 435 or some shit.

I cooled my 600 very effectively with rather less than 100 cfm. (glazed hood) Try it. cn

I would go 6" if it was me.
I cool 8x 1000w lights with 2-6" inline fans, 1 pushing and 1 pulling and it is just barely adequate until summer heat arrives. You are always better off with extra cfm's so you can turn them down a little to lower sound

sound isnt an issue i just want to be able to cool the 2 600s and the 400 adequately and i dont wanna spent too little money on something too small.

For my recent grow I chose the 6-inch MaxFan, rated at 334 cfm iirc. I ran it throttled way back with a variable transformer, well below it's lowest switch setting. I would say such a fan will serve you well, unless you have difficulty controlling the temp of your intake air. cn

how many lights are you cooling and what watts?

I cooled one 600. I'd comfily cool three with that fan. i was using maybe 10% of its capacity. cn
