SKU CH-1KV3-WANF3

Internal power cable for Delta FFB03812VHN-A 3828 38x38x28mm DC12V .7A PWM 4-wire cooling fan

  • Designed for Delta FFB03812VHN-A 3828 fan
  • 38×38×28 mm form factor fits tight spaces
  • DC 12 V 0.7 A rating matches original spec
  • Four-wire PWM connector enables speed control

Compatible 3828 fan power cable

This cable connects the Delta FFB03812VHN-A 3828 cooling fan to a four wire PWM header. It matches the 38 by 38 by 28 millimetre form factor and carries 12 volt DC power at 0.7 ampere. Builders fitting this specific 38 millimetre cooler can install it without adapting generic leads.

Thermals noise and power draw

The cable itself adds no heat or acoustic load and draws only the 0.7 ampere rated by the fan at 12 volts. Normal operation stays within the PWM control specification so the motherboard regulates speed quietly. Buyers needing a different pin count or voltage will require a separate harness.

Questions about this item

How do I connect the 4-wire PWM cable to the Delta FFB03812VHN-A fan?

Align the keyed 4-pin connector with the fan header, press straight in until the latch clicks, and route the wires clear of the 38 mm frame so the blades cannot snag them.

When should I replace the cable if the fan runs at 12 V and 0.7 A continuously?

Inspect the insulation and crimps every 12 months; replace the cable if you see discoloration, stiffening, or intermittent PWM signal causing speed fluctuations.
