SKU CH-AAMS-F3PTM

A pack of twenty 12 V PWM case fans with four-wire temperature control for system cooling

  • 20 fans included for multi-case or cluster builds
  • 12 V PWM speed control adjusts airflow to thermal load
  • Four-wire interface enables motherboard fan-curve management
  • Delta EFB0812HHB 8015 model rated at .4 A current draw

20-Pack Delta EFB0812HHB 8015 PWM Fans

This bundle supplies twenty Delta EFB0812HHB 8015 case fans for system builders or integrators outfitting multiple chassis. Each unit runs on 12 V power and draws .4 A through a four-wire PWM connector. The temperature-control function adjusts speed automatically to match thermal load.

PWM Temperature Control Across Twenty Units

The four-wire PWM interface lets the motherboard or fan controller regulate every fan in the pack without manual switches. Automatic temperature response reduces acoustic output during light workloads and increases airflow when components run hot. Buyers needing voltage-only control or a different frame size should look elsewhere.

Questions about this item

How often will the 12 V .4 A PWM fans need bearing maintenance or replacement?

The Delta EFB0812HHB 8015 uses sealed bearings that are rated for continuous operation; no routine lubrication is required, and replacement is only needed if noise or vibration develops after extended use.

What limit appears first when the 20 fans run at full PWM duty for long periods?

The 0.4 A per fan current draw sets the practical limit; a 12 V rail must supply up to 8 A total, so the power-delivery capacity of the motherboard or fan hub is the first constraint.
