Hey everyone, I recently installed the Arctic Liquid Freezer 3 AIO cooler in my rig, with the pump positioned below the top of the radiator and the tubes at the bottom of the radiator fans—a setup I've heard is optimal. However, I'm noticing a weird noise coming from the AIO pump, and I'm puzzled about what could be causing it.

Could it be air bubbles trapped in the water pump? I've always kept the pump positioned correctly, never above the radiator when the AIO is running. Has anyone else experienced this issue with their AIO setup, or does anyone have suggestions on how to troubleshoot and fix this noise? Or could it be a Fan or the GPU?

Any advice would be greatly appreciated!

Use a cardboard tube or rolled up sheet of paper to determine if you can narrow down the sound's location.

Hold one end to your ear and carefully "aim" the other end around the AIO, fans, etc. to locate the source.
