  • 120 × 120 × 38 mm frame fits standard mounts
  • Four-wire interface supports speed monitoring and PWM control

Delta 48 V PWM case fan

The Delta AFC1248DE is a 120 mm square, 38 mm thick axial fan that runs on 48 V DC and draws 1.64 A for 78.7 W. Its four-wire PWM interface allows the motherboard or fan controller to vary speed automatically based on temperature. The double ball-bearing motor is rated for maintenance-free, long-life operation in industrial and high-airflow PC builds.

Compatibility check

Verify that your system provides a 48 V DC supply capable of at least 1.64 A per fan; standard 12 V headers will not power this unit. Confirm the mounting holes match a 120 mm pattern and that 38 mm thickness clears surrounding components. The four-pin connector must mate with a PWM header wired for 48 V control voltage.

Thermals, noise and power

At full 48 V input the fan consumes 78.7 W and moves a large air volume with high static pressure for dense heatsinks or restrictive chassis. PWM control reduces speed, power draw and acoustic output when thermal load is light. Double ball bearings keep running noise consistent over the extended service life.

Highlights

  • PWM speed control enables precise cooling adjustment
  • 48 V 1.64 A input delivers 78.7 W high airflow
  • Double ball bearings provide maintenance-free long life
  • 120 × 120 × 38 mm frame fits standard mounts
  • Four-wire interface supports speed monitoring and PWM control

Questions about this item

Does the AFC1248DEProduct come with mounting screws or a power adapter, or do I need to buy them separately?

The fan includes a four-wire PWM interface for direct connection to a compatible 48 V header; mounting hardware and any voltage conversion are not included.

The listing shows a single 48 V 1.64 A model — how do I confirm this version matches my chassis and power budget?

Check that your system provides a 48 V DC supply capable of 78.7 W and that the 120 × 120 × 38 mm frame fits your mounting points before ordering.

What does the 78.7 W rating mean for actual airflow and noise once the fan is installed in a case?

At full PWM duty the double ball-bearing motor draws 78.7 W to deliver high static pressure and volume; acoustic output will vary with case restriction and speed curve.
