I find it annoying that even at silent running speed, you can still hear your own screws at 180, when you shouldn't be able to.

Silent running isn't a magical switch that makes machinery stop making noise; it is an instruction to the crew to stop especially loud tasks and avoid making unnecessary noise. Driving a 1,200-ton steel tube through the water at four knots takes a fair bit of oomph, so yes, you're going to get a noticeable of engine and cavatation noise, even at one-third-ahead in silent running. The only way to truly silence the noise an electric motor makes in a hydrophone (be it yours or a destroyer's) is to turn it off.
Of course, when you start dialing it back to speeds of one to two knots, your own engine noise gets quiet enough that you'll be able to hear nearby and fast-moving ships over it, but the only way you're going to get the full effectiveness of your hydrophone in that rear arc is to stop the engine.
