The pump that blew up and still works

[Turtle Rig]

So I had my pump on balanced,, so it was quiet, But not that quiet, its the noiseist thing in my case,, I turn all fans off , and you hear loud the pump noise, If it was silent this system would be killer.  So upon using it I started to get a loud buzzing sound which wasnt good and loud.  But the temps remained the same idle and load.  Then the buzz got less,,,,, but still did it,,,,,, and now you can barely hear the buzz.  If I changed to performance or quiet there is no effect no more.  When before there was huge effect in extra noise.  Balanced and performance had nice noise difference and no temp difference so I left it on balanced...  It has now been 2 weeks and things are running great and no more easy to hear buzz sound,  But I noticed with the 2 AIO kits the same noise,, with a little buzz,, and lots of noise.
