Compact 40 mm case fan

The SXDOOL KD1204PKV1 MS is a 40 mm square frame fan designed for tight spaces in small-form-factor PCs, embedded boards or industrial enclosures. It runs on 12 V and draws 1.2 W through a simple two-pin connector. No LED lighting is fitted.

Two-pin voltage control

The two-pin power lead means speed is governed only by the voltage supplied; there is no PWM signal wire for automatic duty-cycle adjustment. Your motherboard or fan controller must support voltage regulation on that header, otherwise the fan will run at full speed continuously.

Clearance and header check

Verify that the mounting holes match a 40 mm pattern and that 20 mm of depth is available behind the fan frame. Confirm the board header is a standard two-pin 12 V socket and that your fan-control software can modulate voltage on that header if variable speed is required.

Questions about this item

Is the 40mm 12V 1.2W 2-pin version the only size available for this model?

The listed specifications show a single 40mm frame with 12V 1.2W power draw and a 2-pin connector; no other sizes or power variants are mentioned for this KD1204PKV1 MS fan.

What does the 1.2W rating mean for airflow and noise once the fan is installed?

At 1.2W the motor draws modest current, so the fan suits tight 40mm spaces where low power and quiet operation matter more than maximum airflow.

What does the 2-pin connector limit compared with 3-pin or 4-pin headers?

A 2-pin connector supplies fixed 12V power without a tachometer or PWM signal, so speed cannot be monitored or adjusted by the motherboard.
