Aqua Computer D5 pump + Aquasuite high rpm

Thursday, December 31st 2020, 1:14pm

Hi all,

Just replaced a EKWB pump (failed) with a trusty Aqua Computer D5, however, even at 1% rpm control, it's at 1800rpm, previously I ran around 1300rpm at 35% min power. Is there any trickery in the software to reduce the rpm?

Thanks

There could be difference in the PWM control of these pumps. If so, the is no easy way to lower the pump speed. In my case, D5 pump is nearly inaudible inside the chassis even at 3300 rpm. It is mounted on EK Revo mount.

My chinese D5 pump runs @ ~1850 rpm at 1% PWM duty cycle.

Sadly even at 1800rpm, it's still audible (slight motor whine) which is audible over my fans. At least at idle.
