Have you set the CPU fan connector to use PWM in the BIOS?. That is what I did for my Asus Gene VII.

couldt find it anywhere in bios...
will look again...

Its quite possible your motherboard CPU header cant provide enough Watts on its own to power the pump as its rated at 18w.

Dont you plug the molex to the psu aswell as the PWM cable to the mobo if you want variable speed with these anyways?

it is powered by molex.
when plugged in to pwn for cpu fan, it just doesn't start at all....

Solved.

it was working when connected to MOBO, but it is so quiet on slow revs, that I couldnt hear it ;D

I was only relying on my hearing rather then touch it if it vibrates as well

Thanks all
I can work in quiet now
