If you are experiencing an issue where you hear an audible rattling noise from the pump, try disconnecting the fans that are connected to the radiator and see if the noise continues. We have seen the fans creating noise over time after long 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, it could possibly be air bubbles in the pump 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 this tutorial to quiet the Asetek cooler.
If the troubleshooting steps above did not work, contact our Customer Support Team for further assistance or a replacement unit.
