  • Reliable 12 V 2 A power delivery
  • Compact 40 × 40 × 28 mm footprint fits tight spaces
  • New condition ensures full performance from day one

12 V 2 A PWM internal cable

This four-wire cable connects a 40 mm square fan to a 12 V header on a motherboard or controller. Pulse-width modulation lets the board vary speed without changing voltage. The 2 A rating supports most 4028 frame fans in server or workstation chassis.

Builders needing voltage control only

Buyers who require a three-wire voltage-controlled header should choose a different cable. Systems that demand a larger frame size or higher current capacity will not be served by this 4028-specific lead.

Highlights

  • Precise PWM speed control via 4-wire design
  • Reliable 12 V 2 A power delivery
  • Compact 40 × 40 × 28 mm footprint fits tight spaces

Questions about this item

What is the difference between the 4012 and 4028 versions?

The model code MGT4012PB-W28 refers to a single 40 mm square fan with a 28 mm frame depth; 4012 and 4028 are not separate options.

How does the 2 A current rating work with a 12 V PWM fan header?

The 4-wire cable delivers up to 2 A at 12 V, matching standard motherboard PWM headers that supply 12 V and accept PWM speed control signals.
