That's nice move.
You replace Molex with SATA.
Molex is not problematic because power, only because connection.
Molex never can't be durable as SATA Power Connector.
D5 pumps die very rear, but because of that many of them are loud.
It's best option if you can find original Laing D5 and someone to make you SATA Power connector nicely to crimp wire and install sleeve before install SATA Connector.
And Dazmode say that, and if he who have experience with hundreds pumps and dozens of every brand say Laing original are best we should listen.
Even if no PWM control. Set on speed 3, if D5 work properly speed 3 (3300RPM) is silent even out of case and you don't need to move control never any more.
And for DDC same, but DDC is easier to find original Laing.
DDC for me look nicer and more compact but I would never use because influence on temperature and die more often and shorter life.
