DESCRIPTION
Genuine OEM Delta Electronics DC Cooling Fan removed from an HP LaserJet Pro P1606dn laser printer.
This is an internal cooling fan assembly used to provide airflow and thermal management inside the printer. Proper cooling is important for maintaining the operating temperature of internal electronic and mechanical components during extended printing.
The fan is manufactured by Delta Electronics and is clearly marked:
Model: AUB0624HB
DC 24V – 0.09A
3-Wire
Canon P/N: RK2-3448
Size: 60 × 60 × 15 mm
The RK2-3448/AUB0624HB combination is documented and sold as a cooling fan for HP LaserJet-family equipment, including the P1606dn/M1536 platform.
WHAT DOES THIS FAN DO?
The cooling fan provides forced airflow inside the printer to help remove heat and maintain appropriate operating temperatures for internal components.
Laser printers generate significant heat during operation. Proper airflow can be important for components such as:
- Internal electronics
- Power/control components
- Printer engine components
- Areas surrounding heat-generating assemblies
A failed or degraded cooling fan can potentially cause inadequate airflow, excessive internal temperatures, abnormal fan noise, or printer shutdown/protection behavior depending on the specific circuit being cooled.
POSSIBLE SYMPTOMS OF A BAD FAN
A defective cooling fan can produce symptoms such as:
- Fan does not spin
- Fan spins intermittently
- Excessive fan noise
- Grinding or bearing noise
- Fan starts and stops unexpectedly
- Reduced airflow
- Printer overheating
- Printer shutting down after extended operation
- Abnormal internal temperature conditions
If the original fan has a seized bearing, excessive noise, or has stopped operating, replacing it with a matching fan can restore proper airflow.

BUYER VERIFICATION
Before purchasing, please verify that your original fan matches:
Model: AUB0624HB
Part Number: RK2-3448
Voltage: 24V DC
Current: 0.09A
Size: 60 × 60 × 15 mm
Wiring: 3-wire
Please compare the connector, wire configuration, mounting holes and physical dimensions with your original fan.
This is particularly important because 24V cooling fans with similar dimensions can have different current ratings, connectors and wire configurations.
