Pump noise at startup

post #1 of 5
Thread Starter 
I have the D5 Vario pump/res combo from xspc and after the computer sits for a while, when I start up the computer it makes a grinding noise like it is dry. Is the pump going bad or is there a fix to this? the pump is less then a year old frown.gif

How long since the last time you bleed your loop?
Im thinking that maybe some bubbles could be rising up to your pump and accumulate over time as it sits. It only does it when it's been sitting for a while? How long does the dry noise last?

Does your loop make any gargling noises?

I recently tore apart and bled the loop (About 2 weeks ago) it lasts for roughly 1 second and then runs normally. I've tried to shake up the case and get all of the bubbles through but I believe they are all out. There is no small bubbles that come though even.

Are you using pump control with PWM or something? If so, the first second noise is probably full speed and then it reduces after POST. Like PepeLapiu said, one second when booting is not a worry.
