Delefun 12038A DC brushless fan for industrial and server cooling
The Delefun 12038A DC brushless fan is designed for high-load cooling scenarios where a thicker 38mm profile helps support stronger pressure-focused airflow. With a PBT frame/impeller, Class A insulation, and bearing options, it’s a practical choice for industrial chassis, PC/server environments, and continuous-duty enclosures.
Overview: 120x120x38mm dual ball DC brushless fan
The 120×120×38mm size is widely used in industrial cooling and dense server environments where airflow must remain stable under restriction. If you need a 120x120x38mm dual ball DC brushless fan, the 12038A series provides a robust mechanical structure and reliable insulation performance.

Why choose a 12038 fan for dense cooling environments?
Thicker 38mm profile for pressure-focused airflow
Compared with thinner 25mm formats, 38mm fans are often selected where static pressure matters more, such as dense server racks and restrictive airflow paths. For these scenarios, a high static pressure 12038 fan for server racks helps maintain airflow consistency in continuous operation.
PBT structure and insulation for long-term use
A PBT frame and impeller support structural integrity, while Class A insulation supports stable operation over wide temperature ranges in demanding environments.
Typical applications
- Server racks: dense chassis cooling and airflow stability under resistance
- High-end workstations: high-load PC cooling where pressure-focused airflow is required
- Industrial enclosures: cabinet ventilation and equipment thermal management

FAQ
Is the 12038A series compatible with standard 120mm mounts?
The overall size is 120×120×38mm. For fitment, verify the mounting hole center distance (105mm) and hole diameter (4.5mm) against your chassis or bracket.
Which bearing option should I choose?
For long-life stability in higher-uptime environments, dual ball bearing is commonly selected. Longlife sleeve may be suitable for budget-sensitive applications depending on duty cycle.
