Black sleeved cable with SATA plug splitting to five fan connectors

Graviton

Graviton SATA 15-Pin to 5 Fan 3/4-Pin PWM Power Adapter Cable

SKU CH-HB4S-0FHP4

Connects up to five 3-pin or 4-pin PWM case fans to a 15-pin SATA power connector at 12V

  • Powers up to five 12V fans from one SATA connector
  • 15-pin SATA input fits standard power-supply cables
  • Five 3/4-pin outputs accept both PWM and voltage-controlled fans
  • 24 AWG tinned-copper conductors rated for 80 °C operation
  • Black sleeving and connectors keep wiring tidy inside the case

SATA Fan Splitter for Five Cooling Fans

This adapter cable connects a single 15-pin SATA power connector from the power supply to five 3-pin or 4-pin PWM case fans. It is designed for builders who need more fan headers than the motherboard provides. The cable uses 1007 24AWG tinned copper wire with PVC insulation and a 1.4 mm outer diameter.

Thermals Noise and Power Draw

The assembly is rated for 12 V operation and an 80 °C temperature limit. All five fans draw power directly from the PSU SATA line, bypassing the motherboard fan headers entirely. Black sleeving and connectors reduce visual clutter inside the chassis.

Upgrade Path and Limits

This cable replaces the need for multiple motherboard fan headers or a separate powered hub when only SATA power leads are spare. It is not suited for systems that lack free SATA power connectors or for fans requiring voltage control beyond standard PWM signalling.

Highlights

  • Powers up to five 12V fans from one SATA connector

  • Five 3/4-pin outputs accept both PWM and voltage-controlled fans
  • 24 AWG tinned-copper conductors rated for 80 °C operation
  • Black sleeving and connectors keep wiring tidy inside the case

Questions about this item

How do I connect the 15-pin SATA plug to power five fans, and what is the common mistake?

Plug the SATA end into a spare PSU SATA power lead; the mistake is forcing the L-shaped key the wrong way, which bends pins and breaks the 12 V supply.

What upkeep will the 1007 24 AWG tinned-copper cable with PVC insulation need over time?

Inspect the 1.4 mm OD sleeved wires once a year for cracked insulation or loose fan headers; reseat any connector that feels loose to keep 12 V delivery stable.

At what point does the adapter hit its limit when all five fans run continuously?

The shared SATA rail caps total current at the PSU’s 12 V rating, so sustained full-speed PWM on five fans will throttle or shut down once that rail is saturated.
