Zyvpee DS12025B12H 120mm 12V 0.75A 4-Pin PWM Case Fan

Zyvpee DS12025B12H 120mm PWM Case Fan

The Zyvpee DS12025B12H is a 120mm case fan designed for system cooling in desktop computers. It operates on 12V DC power drawing 0.75A and uses a 4-pin PWM connector for automatic speed control. The unit suits builders replacing a noisy or failed fan in compatible chassis or CPU coolers.

Check 4-pin PWM header and 120mm mounting points

Verify that your motherboard or fan controller provides a 4-pin PWM header to enable speed regulation. Confirm the case or heatsink offers 120mm mounting holes with 25mm thickness clearance. Cross-reference the part numbers 31503170, TD330, TD440, 03X3948 or 46U3197 to ensure direct replacement compatibility.

Ball bearing construction

The fan uses a ball bearing for durable rotation and a black non-LED frame measuring 120 by 25 millimetres. The 4-wire PWM plug carries power, ground, tachometer and control signals on a single cable. This layout allows straightforward installation in standard fan mounts without proprietary brackets or adapters.
