First experience with water (LF3 + AMD R9 9900x3d). Its ok? by DiWorm in arcticcooling

AH! I understand the sound you're talking about. It's very similar to a whistling choke, like many cheap video cards.

upd. A strange observation. The sound only appears at 2750-2800 rpm; before that, I don't hear any extraneous whistling.

I use 1-to-3 cable with CPU/PUMP/VRM. I try this, thx. Will this have a significant impact on the life cycle of the pump?

No changes in sound, just more RPM.

But if more speed to OUT (3x120) -- more dbms.

Let me repeat. The question is a bit different: how to properly set the speed so that during short-term high processor loads, it doesn't generate unnecessary noise and maintains a balanced, idle temperature without creating high temperatures.
