Keeping it down

You'll rarely hear a sound from the Ion SFX Gold, mainly due to a semi-passive mode that only activates the fan when it's really necessary. Even then, the true FDB bearings will make sure it remains very discrete.

  • The semi-passive Zero RPM mode maintains total silence under light loads.
  • The custom-tailored 120 mm fan with FDB bearings ensures discrete operation even under heavy use.

Full modular design

Reduced clutter results in a clean and simple installation.

The power of flexibility

Thanks to an ultra-high strand count wire and special insulation, our UltraFlex DC wire bends and twists effortlessly to fit your installation instead of fighting it.

  • Combining an increased strand-count and reduced diameter of just 0.08 mm allows thinner, more flexible cables.
  • Specially formulated insulation increases flexibility without impacting efficiency or current capacity.
  • Cables flex and flow with ease for near-effortless routing and superior cable management opportunities.
  • Cables bend and twist to make for easy connections in tight spaces with less resistance and strain.
