SanAce40 40 mm case fan

This 12 V DC fan carries the SanAce40 model code 9PH0412N7D04 and draws 0.26 A. The 4015 frame size fits tight spaces in small-form-factor builds or server blades where larger rotors cannot be installed. A three-wire lead supplies power, ground and a tachometer signal for speed monitoring by the motherboard or fan controller.

Three-wire speed reporting only

The tachometer output lets the system read RPM but does not accept a PWM control signal, so voltage regulation is the only way to change speed. Builders who need closed-loop PWM control or variable-speed headers that require a fourth wire cannot use this fan for automatic thermal management.

Questions about this item

Which 40 mm SanAce40 model should I pick for a 12 V header?

The 9PH0412N7D04 is the 12 V variant that draws 0.26 A and fits a standard 3-line fan header.

What does the 4015 figure mean for airflow and noise once installed?

4015 RPM is the maximum rotational speed; at full voltage the 40 mm frame delivers its peak airflow with a corresponding rise in audible noise.
