SKU CH-RP37-35PE3

A 40 mm square dual-fan assembly rated 12 V 0.75 A fits tight 40×40×38 mm spaces

  • 12 V 0.75 A power rating ensures stable double-fan operation
  • Compact 40 × 40 × 38 mm frame fits tight chassis spaces
  • Internal power cable design simplifies routing inside the case
  • New condition guarantees reliable performance from first use

Product identity

This is a new internal power cable designed to connect two 40 mm by 40 mm cooling fans that each draw 0.75 A at 12 V. It suits technicians and hobbyists wiring dual-fan arrays inside custom enclosures or replacement builds.

Critical specification

The cable is rated for 12 V and 0.75 A per fan, so it only works where the fans and the power source both match those exact figures. Builders needing higher current, a different voltage or a single-fan lead cannot use this part.

Highlights

  • 12 V 0.75 A power rating ensures stable double-fan operation
  • Compact 40 × 40 × 38 mm frame fits tight chassis spaces
  • Internal power cable design simplifies routing inside the case
  • New condition guarantees reliable performance from first use

Questions about this item

What does the 0.75 A rating mean for the 12 V fans in my system?

The 0.75 A rating shows the maximum current each 12 V fan can draw, so a single motherboard header rated for 1 A can safely power one fan but not both.

What connector standard does the double-fan cable use and what does it limit?

The cable uses a standard 3-pin 12 V fan header, limiting control to voltage-based speed regulation and capping total current to the header's rating.
