12038 4-Wire PWM Server Cooling Fan Replacement for 2B12038B48M P076, 120×120×38mm Square DC Fan 48V 0.54A High Airflow Industrial Cooler for Computer Chassis Server Cabinet Equipment

This 120×120×38mm square DC cooling fan is a perfect drop-in replacement for the original 2B12038B48M P076 server fan, matching all original electrical parameters and mounting hole positions without modification. It runs on DC 48V rated voltage with 0.54A rated current to fully meet the power demand of industrial servers, storage cabinets and large computer chassis.

Adopting a 4-wire PWM wiring harness, this fan supports real-time speed adjustment controlled by the mainboard or host system. It automatically lowers rotation speed at low temperature to reduce operating noise and raises speed to boost airflow when equipment overheats, balancing cooling efficiency and quietness.

The fan blade and frame are engineered for high static pressure and strong airflow, which can quickly exhaust accumulated hot air inside closed server cabinets, effectively lowering the operating temperature of CPUs, power supplies and hard drive arrays to prevent overheating shutdown or hardware damage.

Equipped with wear-resistant dual ball bearings, the fan maintains stable long-term continuous operation with low vibration and low noise. The thickened outer frame enhances structural stability and reduces resonance during high-speed rotation. Standard mounting holes align perfectly with the original fan, enabling fast plug-and-play installation.

Widely applicable to industrial servers, network cabinets, industrial control equipment, large computer cases and other devices requiring 48V 12038 cooling fans. It is an ideal maintenance spare part to replace aging, noisy or faulty original cooling fans.
