Pump working hard

[Imperial]

I've got AIO Navis Pro 240 (in retrospect i should not).
And from the sound it feels like it's pump going 100% all the time and and noise is a bit annoying.  It's connected via SATA power cable and is a single device on rail. 

Before it was on a same rail as 2 SSD and HDD ( i changed to manage cables easier) and i think it made a lot of less noise. Might this be the case that it guess less power with more stuff on same cable?
Anyways is there any way to regulate pump speeds? There is no pump header, just single sata power cable.

Thermals are fine (~35 idle, ~50-60 on load) and coolers are spinning on low RPMs.
I'm thinking about switching back to stock cooler for my Ryzen 2600 just for the noise alone (it's ment to be low noise build).

Most of the times noise in a pump means it has some air trapped in it.

Changing the connector should not change anything.
