Fan Alphacool 24829 8 cm Black 1000-6000 RPM 130.83 m³/h

The Alphacool 24829 ES is an 80 mm server/workstation fan engineered for high airflow and high static pressure. It operates across a wide speed range from 1000 to 6000 RPM, delivers up to 130.83 m³/h airflow and a maximum air pressure of 14.29 mmH2O. The fan uses a durable double ball bearing and runs on 7–14 V with a 4-pin PWM connector for precise speed control in server environments.

Advantages

This Alphacool 8 cm fan uses 4-pin PWM control to maintain full supply voltage while enabling a broad controllable speed range, including the ability to stop at 0% PWM. A soft-start feature reduces mechanical stress on startup, extending service life. Double ball bearings provide improved durability and low vibration under continuous heavy load. Built-in protection circuits allow automatic restart at reduced speed if blocked, tolerate incorrect short-term polarity connections, and protect the electronics against burn-out for at least 5 seconds.

Suitable for

• Server racks and enterprise systems requiring PWM-controlled fans
• Cooling radiators where high static pressure is needed
• High-performance PC cases and workstations

Key specifications

How to use

Connect the fan to a compatible 4-pin PWM header on the motherboard or fan controller that supports 7–14 V operation. Ensure correct polarity and secure mounting to avoid vibrations. Configure PWM control in the system BIOS or fan controller to set desired speed profiles; the fan will accept 0% PWM for a complete stop if supported by the controller. Allow clearance around the fan blades and avoid placing fingers or objects near the blades when powered.

Recommendations

For radiator use, configure a higher PWM duty cycle to exploit the fan's high static pressure. In server racks, use controlled fan curves to balance airflow and energy consumption; the soft-start and protection circuits permit safe operation even under temporary blockages.
