I just bought two of these and they are awesome push a whole lot of air and whisper quiet
fans
I run 2 x 250 mh and my temp doesn't flucuate at all when they are on the fans only come on when the lights come on

yeah they will fit but i would use those 4 3/4 ones less rpm = less noise and the bigger one push alot more air. a jig saw will fix that size of the hole
