How to quiet the power supply?

I have a G4 MDD dual 1.25GHz system (M8570). The samsung 400W power supply has always been fairly noisy and I am wondering if anyone has ever fixed this. I have heard that the AcBel is the noisy one, but this one seems to have become about as bad. Are there replacement fans that you can install? Anyone have the specs for them?
