Universal Pump Decoupling Kit

The Phobya Noise Destructor Foam kit is a universal decoupling solution designed for watercooling pumps. It uses two rubber sheets and a foam core to absorb vibration and reduce operating noise. Compatible models include Laing DDC, Laing D5, Eheim 1046, Eheim 1048, Magicool 12V, Phobya DC 260 and DC 400, and EK-DCP 2.2 and DCP 4.0. The kit measures 96 x 80 x 30mm.

Vibration Limits and Compatibility

The foam core and rubber sheets dampen motor vibration but do not eliminate fluid flow noise or resonance from attached tubing. Pre-punched holes match the listed pump models only; other pumps require custom drilling. The adhesive tape provides a simple bond, yet long-term hold on vertical surfaces may weaken without mechanical screws. This kit addresses pump vibration, not radiator or fan noise.

Installation Notes and Common Issues

Both rubber sheets include double-sided tape for a tool-free adhesive mount. For a secure fix, screws can be used through the pre-drilled holes, though mounting hardware is not supplied. A frequent issue is forgetting to remove all four protective foils before stacking the layers. Builders needing a specific hole pattern not covered by the pre-punched options must drill their own.
