I got this one on amazon and it works perfect and is half the price!
I use this fan with this and have had really good results with it. The fan has been running like a champ for 3 months solid now and I don't have any problems with smell whatsoever.
The iPower fans seem to be junk. Here's the one I bought: a 6" Hydrofarm, 400CFM (actually an ActiveAir brand fan). Much better than the 175 the ipower 6" was pushing.
It's loud at full blast, and probably more than you need. This is good though, because you can get a speed controller to turn it down. The fan gets much quieter even at 75%, and I run mine at less than 50% to cool my small cab w/aircooled 400w HPS. You can get this speed controller if you don't mind a slightly annoying electric hum from your fan (I have this and sleep in the room with it at night), or you could get the more expensive variac controller that eliminates this hum (and probably helps your fan last longer too).
The centrifugal inline fans are much more powerful than the axial booster fans, and will force air through a carbon filter easily, so get one that is sized correctly for the fan. (heres mine, sized for that hydrofarm/activeair fan)
I keep a steady 78º-79ºF in the cabinet (2.5'x1.5'x4' grow space) with 75º-77ºF ambient room temps, and the air exhausted right back into the room (central air keeping the room at 76ºF helps).
