should I run my fans to keep lights cool?

[Gools]

I have changed around my setup and am now running a Reefkeeper 2, so I have it turn on my fans when the tank hits a certain temp. But lately it's been cool in my basement, cause I've been leaving the window open, so the tank stays cool. So the fans haven't turned on, very nice not having to listen to the extra noise, but when I open the canopy to feel very hot, and the braces, and black trim are very warm. So I'm just wondering if I should have them turn on when the halides turn on? Running 2- 400w, and 2 -175w, plus 4 54w T5's.
Any thoughts?
Thanks
