Hello All,
about two years ago i upgrade my pump setup and bought two EK-DDC 3.2 PWM (12V PWM pump) (i use it with the old version of EK DUAL DDC TOP).
I was pretty happy at begin, it's was work good with aquaero 5 xt.
But very soon troubles come.
Some time both pump not start properly or have very big delay (about 60 -90 seconds) sometimes pumps have unstable rpm, and time to time i hear strange noise from pumps
but after i plug them directly to motherboard they work mostly normal.
And real trouble comes a few months ago.
Both pumps become pretty noisy. They have a tickling noise like very old PWM fans.
And you can hear things like this

or this https://www.youtube.com/watch?v=B-mMiBwL4Z4 (full rpm)
they only operable on 1300 rpm
and seems one pump have mechanical trouble with the impeller.
I have old pwm pump and i plan change failed impeller.
But still, i have trouble with electronics.
Pumps have the same trouble with a delay on start. But now this trouble appear at any type of connection.
And even more time to time pump just won't start.
I wrote to EK, but they just say: warranty is end, and offered me 10% discount on new one
I know it's easy way just buy new, but i don't have free money at moment on new two pumps (i like how dual setup works
)
So maybe someone has any ideas what to do?
ps. pumps not overheated. from begin i place a fan near them
