SXD6038B24H-RDP 24V PWM Cooling Fan
60 x 60 x 38 mm, 24V DC high-speed fan with PWM control and RDB locked-rotor alarm. Ball bearing; 1.1 A rated running current and 1.40 A startup current.
SXD6038B24H-RDP is a 60 x 60 x 38 mm 24V DC brushless fan with a specified speed of 16500 RPM +/-10%. This configuration selects PWM control and an RDB locked-rotor alarm, not FG tachometer output.

Maximum airflow and maximum static pressure are different endpoints, not a simultaneous duty point. Confirm the current configuration and test conditions before purchase.
Compact equipment with a restricted airflow path
Review this candidate where a 60 mm frame and 38 mm depth are available. Compare measured system resistance with the matching P-Q curve; do not infer equipment cooling capacity from speed alone.
Separate speed control from fault reporting
PWM is the control input; RDB is the selected alarm function. Review alarm logic levels, timing and the controller circuit before deciding how a stalled fan will be detected.
Acoustic and power budget
Rated running current is 1.1 A at 24V DC; startup current is 1.40 A. Rated input power is 26.4 W. Review startup behavior and supply capacity with a configuration-matched sample. The specified noise is 67.5 dB(A), maximum 70.8 dB(A); validate the acoustic budget in the target equipment.
Frequently Asked Questions
Is the RDB wire an RPM feedback output?
No. The specification selects RDB locked-rotor alarm and leaves tachometer output unselected. Confirm the alarm truth table with the approved interface drawing; do not use it as FG pulse feedback.
What PWM frequency is listed for SXD6038B24H-RDP?
The specification lists 1-50 kHz, with 25 kHz preferred. Match the controller voltage levels and input requirements as well as frequency before connection.
What happens at zero PWM duty?
The reviewed specification states that the fan stops at 0% duty. Confirm this on the released sample and define how the equipment distinguishes commanded stop from a fault.
Are 68.5 CFM and 87.6 mmH2O available together?
No. Airflow is specified at zero static pressure and pressure at zero airflow. Select the operating point from the P-Q curve with the equipment resistance.
Is this model a quiet desktop cooling fan?
The specification records 67.5 dB(A), maximum 70.8 dB(A), under its test conditions. Check the acoustic budget; do not position this high-speed configuration as a low-noise fan.
Can an arbitrary 6038 fan substitute for the RDP configuration?
No. A replacement must match voltage, power demand, airflow-pressure behavior, PWM requirements and alarm interface as well as mounting dimensions.
