## Summary description

The Alphacool 24823 is a 4 cm black fan designed for efficient cooling. It operates at a speed range of 400 to 10000 RPM, providing an airflow of 20.39 m³/h and a maximum air pressure of 11.93 mmH2O. With a ball bearing design, it ensures durability and reliability. Suitable for various computer cooling applications, it operates at a voltage of 7 to 14 V.

## Long description

The Alphacool 24823 is a 4 cm black enterprise fan developed for servers and workstations. It uses a 4-pin PWM connector for precise speed control across a wide RPM range (400–10,000 RPM) and delivers an airflow of 20.39 m³/h with a maximum static pressure of 11.93 mmH2O. The fan operates at 7–14 V and features double ball bearings for increased durability and low vibration, making it suitable for radiator mounting or as a high-performance case fan.
Advantages
The 4-pin PWM connection provides full-voltage operation with pulse-width modulation control, enabling a broad, energy-efficient speed range and allowing the fan to stop at 0% PWM. Double ball bearings improve service life and running smoothness compared with plain bearings. Built-in protection circuits include soft start, automatic restart at reduced speed if blocked, emergency start that tolerates blockage for up to 72 hours, and short-term protection against damage from incorrect polarity during connection.
Suitable for
 Server cooling and workstation chassis
 Radiator cooling in liquid-cooling loops
 High-performance case ventilation where high static pressure is required
Key specifications

 Speed range: 400–10,000 RPM
 Airflow: 20.39 m³/h
 Maximum static pressure: 11.93 mmH2O
 Voltage: 7–14 V

 EAN: 4250197248235
How to use
Connect the fan to a compatible 4-pin PWM header on a server or motherboard that supports PWM control. Ensure the voltage supplied is within the specified 7–14 V range. Mount the fan securely to the case or radiator using appropriate screws or mounting hardware, taking care that fingers and objects do not contact the blades when the fan is powered. Use system BIOS or fan-control software to configure PWM curves and minimum/maximum speeds according to cooling needs.
Usage recommendations
The fan is intended for enterprise and workstation environments: enable PWM control for energy-efficient operation, avoid placing body parts near spinning blades, and allow the built-in soft-start and protection circuits to operate if the fan becomes blocked. For radiator installations, prioritize static-pressure-optimized orientation and maintain regular dust cleaning to preserve airflow and longevity.
