[Watercooling] Replace Bykski DDC pump with EKWB DDC pump? (self.pcmasterrace)

submitted 1 year ago by Romeowns to c/pcmasterrace

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.

OK, I've opened my Bykski DDC pump fitted to my 7000D disto place and it's identical to the Barrow DDC pump fitted to the LTPRP-04 - both circuit boards are labelled as "Q2C-12B".

Also, this video shows the factory "Q2C-12B" pump in the Barrow LTPRKA-04, and others on Reddit etc have reported success in swapping this out for an EK DDC.

Given this, I'll go ahead and buy the EK DDC 4.2 PWM pump to replace my Bykski "B-PMD3-COV" and report back my findings next week.
