9SG1224P1G03 - 120x120x38mm 12038 DC24V 2A 4-Pin Connector High-Performance Heavy Duty Aluminum PWM Fan
The 9SG1224P1G03 is a heavy-duty, aluminum-frame, 24V DC PWM fan designed for continuous 24x7 operation in servers, power systems, telecom, automation and industrial enclosures. The die-cast aluminum frame provides rigidity and heat resistance, while the 4-wire PWM control lets you dial in airflow and acoustics reliably.

Match 24V rating, PWM control, connector style, and airflow class before substitution. If your assembly requires a specific subcode, use the exact model on the original fan label.
Key Features
☑️ Aluminum frame for maximum rigidity and thermal stability
☑️ 4-wire PWM control for precise speed management
☑️ Ball bearings for long service life in 24x7 duty cycles
☑️ High static pressure design for dense heatsinks and restricted bays
☑️ Standard 120 mm square mounting with 38 mm thickness for enterprise chassis
Fit Notes
- Verify 24V fan header and 4-pin PWM support on your system board or PSU.
- Observe airflow arrow and mounting orientation to match your original installation.
- When replacing one unit in a multi-fan array, match model and RPM class for balanced airflow.
- For CPU or heatsink-related installs, apply fresh thermal compound: Shin-Etsu G751 High Performance Thermal Paste (link here).
