I'm experiencing a rattling/bubbling noise with my Kraken cooler. What should I do?

If you are experiencing an issue where you hear an audible rattling noise from the pump, try disconnecting the fans connected to the radiator and see if the noise continues. We have seen the fans creating noise over time after prolonged use. If the fans are the issue, please contact our Customer Support Team to ask for replacement fans.

If the fans are not the issue, air bubbles in the pump could be causing this noise. Try the following troubleshooting steps to see if it helps to clear out any air bubbles:

• Set the pump to 100% and let it stay like that for 1 hour, then turn it back down and see if the noise goes away.
• Follow the video embedded below on how to work out the bubbles as well.

Note: Please when reinstalling your radiator, make sure it is in the original orientation that it was previously installed in.

If the troubleshooting steps above did not work, please record a video of the issue and upload this video to Google Drive/Dropbox and provide this video of the sound to our customer service team.
