I've got a suggestion, but it's contrary to apparent logic:

Get a second one.

Hook it up in series with the first one, that way you'll have better pressure (and flow) and you won't be straining the pump so much, so the noise will go down.

You really need to wire that pump up differently. It can come on and off with the PSU.

That's the thing, my flow rate is quite good actually, I'm running 1/2 and 3/4" lines with only a few 90° bends. I think that the pump is just messed up or something... Why do I need to wire the pump differently? If the PSU isn't on, the pump is not on. So there is no forgetting about it being off and accidentally powering the system on etc... I think it's just a shitball pump.... There's no more than 1 to 1-1/2 ft head pressure, it should not be straining at all... Lousy Via!
