Asetek AIO pump noise

Just finished up my SM580 build with noctua fans and the Asetek 280mm AIO that Sliger sells. Noticed during assembly that the pump is only 3 pin and I can't find any settings to adjust the RPM of the pump. So the pump is quite noticeable even with music/game noise. Anyone else experience this or have suggestions? Was hoping for a quiet stealth build with no RGB and noise but the pump is very noticeable.

Edit: Thanks for the suggestions all. Asus AI Suite allowed me to set a power curve for the AIO. Can't hear the pump anymore over basic music/game volume.
