cool tube venterlation setup help please!

hiya guys im just wondering if i get two cool tube reflectors for my 600s can i use my fan im already using rvk L1 and hook it up to the cool tubes even tho im useing a sms twin fan speed controler? or will this not be anuf to cool the lights when the fan slows down? thanks peeps

I had a dedicated 240cfm fan for my 2x 600w cool tubes and it was not enough. I hooked them up to my exhaust from carbon filter w/ 440cfm fan now, and it keeps them very cool. The tent stays at whatever the temp in the room is. It's in a spare bedroom, so most of the time it stays at 72-75 deg.

To be honest though, you just have to try it out. One day I just felt the exhaust from the carbon filter fan and it was WAY more flow than the small inline fan I had previously.
