those 120mm fans move some air, i have 2 on my lights one in, one out...and they can double as a blowdryer! you know when they come on,,,if the house is quiet,,,sounds like a small jet engine. but once they are running, you dont notice them.
as for the pump,,,send it to New Orleans,,,that bugger can suck the city dry~ it will definately help your flow~~
