Fans are a little noisy, but only have them on in August, Sept. My fixture does however, make a loud cracking sound when it cools down. Sounds just like glass breaking. Even though I know what it is I still check the tank every time I hear it. Scared the crap out of me the first time!
I got 3 250W MH on my 150 and I got to have fan's on all year round! Tank get's 82+ even in winter if I don't
