need help with Ventilation

[basementdwell]

ok first and foremost I am running a 600 with 6" air fittings. SO far its my only source of cooling till i move my ac in. SO i got i couple of those inline booster fans and its not cutting it as the exhaust any more. SO i need to get a fan and fast. SO i am looking at all the different names and sizes. Well most dont give a db rating so i am out for a 6" inline with some kinda suck or pressure incase i add a bend or filter in the future. But i NEED it to be quiet Thinking some where in the 400cfm range. My room is 8X4X6
Does any one have the hydro farm active air 6" ? Does any one have the cap value line 6" Centrifugal Fan - 435 cfm ? Are they quiet,powerful, any vibrations ? Thanks

It's hard to tell it's on from inside the room. Outside it's not so quiet because it is moving a lot of air. IIRC, it was about 100 bucks shipped.
