Compact 40 mm cooling fan
The TOPLAB FFB0412SHN-ROO is a 4028 form-factor fan measuring 40 by 40 by 28 mm. It draws .6 A and includes a stall alarm for speed monitoring. The unit suits server chassis and embedded systems that require a low-profile axial cooler.
Stall alarm for failure detection
The built-in alarm signals when the rotor stops or drops below threshold, letting the host system react before components overheat. Buyers who need variable-speed PWM control or a different voltage rail should verify compatibility before ordering.

Questions about this item
What does the .6A current draw mean for my power supply?
On a 12V rail the fan draws .6A, so include that load when calculating total 12V demand for the chassis power supply.
What does the stall alarm do in practice?
The stall alarm provides a signal if the fan stops spinning, allowing the server or controller to detect a cooling failure immediately.
