Thanks for the reply! I was afraid it might be a bad sign. I've already ordered a replacement pump/res and will contact corsair support to try for a refund on this one.

So I have a weird issue that happened while I was switching my build from a Fractal Design Mini C to a Lian Li O11D Mini. My XD3 pump/res was working fine a few hours ago when I turned off the computer to take it apart. I took everything out of the old case and rebuilt my loop in the new case, and now the pump wont start up again. It gets power, as it makes a very low and faint vibrating noise, but it doesn't spin up. I have tried to have it plugged into both the new and old power supply, both with pwm plugged into the commander pro and not. I read some previous threads on this forum and tried tilting the case and even shaking the pump (soft tubing so I could unscrew the pump without disconnecting the loop). The only thing I added to the loop was more radiator, I went from 2x240 to 2x360 + 1x240. Have I simply reached the limit of what pressure the pump is able to supply? Here is a video of the sound the pump makes when powered with only molex connected, pwm was disconnected (you might have to turn up your volume to hear the vibrating sound): [ame] [/ame] I bought this pump directly from the corsair EU store, so I don't think it will be a problem to return it if I have to, but it seems weird that the pump suddenly stops working like this. I thought I'd try my luck on the forums and see if someone might have a solution :)
