Gidday team,

I have inherited a watercooled rig from my late father-in-law and the Bykski "B-PMD3-COV" DDC pump on the 7000D distro plate is very rattly at 20% / 1800 RPM (as low as PWM will let it go via Gigabyte X570 BIOs).

I want to replace it with the EKWB EK-Loop DDC 4.2 PWM Motor as this is the only option I have available locally.

I hope that I'll be able to tune down the EKWB pump to below 1800 RPM so it'll be quieter / less rattly. The rig is used mostly for quiet office work and occasional gaming.

Can you please let me know your thoughts on:

• Is this a realistic hope?
• Is this a straightforward task?
• Is there more I need to consider?

Thank you for your time.
