FFB0412VHN-4E73R 40 mm case fan

The FFB0412VHN-4E73R is a new 40 mm square case fan designed for 12 V operation. It suits builders fitting a compact 40×40×28 mm slot in a small-form-factor chassis or replacement cooling for legacy hardware. The three-wire lead provides tachometer feedback for speed monitoring.

Three-wire 12 V specification

The fan runs at 12 V with a rated current of 0.24 A and uses a three-line connector for power, ground and speed signal. Buyers who need a two-pin or four-pin PWM interface should choose a different model. The 4028 frame size limits use to mounting holes spaced for 40 mm centres.
