Yes, it’s a genuine EK pump. I use both in my custom water build. The D5 Next controls the speed of my EK pump through the Fan header. I was hoping to balance the flow between both instead of 1 pump doing most of the work.

I have the D5 next 200pro combo and I am trying to lower the RPMs on the D5. I set the pump power on the mini display to zero and the pump is still moving at 19xx RPM. Still getting 1.2LPM flow rate. Unlike my EK pump Quantum, I can lower to 8xx RPM. The D5 next, I can't figure out how to drop the RPM further. Is this a bug? anyone knows the lowest RPM for D5 next? Thx!

Nevermind. Seems Western Digital Dashboard(3.7.2.5) was blocking update . I exited the app and AquaSuite updated the D5 Next.

Hey Guys! anyone knows how to reset D5 next? I just installed AquaSuite x.57 and clicked on the Firmware update. It stops at 20% and then says upgrade complete, please restart Aqua suite. Problem is the D5 next doesn't reboot, the screen stays off. Buttons not working. Then Aqua Suite says firmware update available again. Anyone knows a fix? thx!
