In a water cooling system, if proper fans are used, the loudest component is the pump. Even if it is already whisper-quiet, it can still be heard in the background.

Hence Alphacool has now developed an insulating box for the most popular of pumps, the Swiftech MCP35x Series, the Laing DDC 1T and 1Plus pumps. This very innovative insulating box is the perfect solution to silence the last source of noise in the system once and for all! The features of the SilentBox are listed below:

Silence:
A completely enclosed box surrounds the pump. This box is additionally lined with foam to additionally decouple the pump and to also absorb the noise from the pump. The In- respectively Outlet holes in the box are still sealed with foam coming from the factory, allowing the user to cut them exactly to size. This avoids sound bridges from forming as the foam can fit perfectly. Even the connection cable is surrounded by foam when the box is closed.

Decounpling, mounting:
Internally the pump is already well-decoupled, bit externally this box offers even more possibilities for additional elimination of vibration: The bottom of the box has 8 M4 threads ifor vibration absorber installation. Hence the whole box can be mounted with e.g. the Decoupling kit for Eheim/Hydor (2x outer thread) 4pcs (Item No.: 52191) or Decoupling kit for Eheim/Hydor/Laing top (1x inner thread/ 1x outer thread) 4pcs (Item No.: 52007).
The box is designed for installation in a 3.5“ drive bay (2 vacant bays required) without added vibration absorbers. Alternatively it can be mounted in a 5.25“ drive bay with vibration absorbers. For this the box has 2 m³ threads on each side.

Mounting screws for direct installation in a 3.5“ HDD bay are included.

Fittings:
Generally it can be said that all fittings can be used if an extension with a maximum outer diameter of 12mm is used. Hence all barbed fittings as well as all compression fittings with a union nut diameter of 12mm at most can be used as well. The Alphacool fittings with Alphacool tops can even be used directly with 13/10mm fittings.

For all other top and fitting compatibilities a collective thread will be created (Forums are still under construction).
