Get the blower that I talk about there. It goes from silent to loud all using the onboard speed control. Big enough to draw the amount of air we need at a very nice noise level. I suspect that with resistance on the intake it will be even quieter.
BillA and Greenman: You guys are correct about choosing the radiator and blower as a unit but the problem is there is a very limited selection of affordable blowers to choose from. On the other hand there is a large selection of radiators to select from. Finding a blower and then finding a radiator may not be Ideal but we simply do not have an unlimited selection here. Out of all the blowers I could find this is the only one that I feel suits me.
Not even mentioning that I dont know of any measured resistance curves for rads/HCs that would suit a blower.
Maybe bill can give some input there. I am pretty much just taking a shot in the dark......
