EK-XRES 140 DDC PWM 3.2 makes super loud noise and runs at full speed

Recommended Posts

Posted · Original PosterOP

Hello I just finished my custom loop to cool my 5820k and dual 980ti. My pump res combo from ek the XRES DDC 140 PWM 3.2 makes a super loud sound and seems to be operating at full speed at all times, I am using an asus rampage v extreme motherboard and have set my pump/res header to pwm silent and it stil runs at full speed is there any way I can fix this? The sound is louder than a stock 290x blower cooler its driving me crazy.

If there's still air in the system the pump can be super loud. Also DDC is not the most quiet pump. Let the system bleed for a few hours, if you see any bubbles in the tubes hit the tube there with something.

Can't help regarding the RPM issue. I always use some kind of program and a custom curve for PWM.

Same setup.  I had to use fan Expert to set the pump speed.   Anything over 1500 RPM starts to be audible.  

Tell my tale to those who ask. Tell it truly; the ill deeds along with the good, and let me be judged accordingly.
