Problem with new Aquastream Ultimate - with PWM high pitch buzzing noise

Freitag, 14. Juli 2017, 21:15


pls need advice. I bought upgrade kit for my XT Ultra, sucessfully change electronics ... looks cool, but when I powering my four Noctua F12 PWN fans from pump, there is very annoing lousy buzzing noise coming from pump electronics ... its really from pump, when I unplug it, its silent ...
Than I try to power fans via Phobya PWM splitter - via molex adapter +12V from molex ( PSU ) and pins 3 and 4 from pump. But than fans are at 100% speed and cannot be controled.
Pls help, I cant send pump to RMA, my watercooling must be working ... And I want to control my fans via pump via temperature curve ( I plant to buy licence for control ).
What is wrong?

Thx for info.

Does the buzzing go away when you push down on the pump with your hand?
