120 mm temperature-controlled case fan

The Delta Sensflow WFC1212B is a 120 mm chassis fan built for systems that need quiet, variable-speed airflow. Its double-ball bearing and seven-blade impeller spin between 1245 and 2447 RPM depending on thermistor input. The two-pin connector draws 0.44 A at 12 V, making it a direct drop-in for standard motherboard headers or fan controllers. Builders who prefer PWM or three-pin speed reporting will need a different model.

Fits 120 mm mounts with 20 cm lead

The 12025 frame matches common 120 mm mounting holes in cases, radiators and heatsinks. A 20 cm two-wire tail reaches nearby headers without extensions. Because speed is governed by an external thermistor circuit, the fan frees the builder from fixed-voltage operation while keeping cabling simple. No LED lighting means the unit stays invisible in windowed builds that favour a dark interior.

Replaces fixed-speed 120 mm two-pin fans

Swapping a constant-RPM two-pin fan for this temperature-controlled unit cuts idle noise from 38 dBA down to 18 dBA while still delivering up to 44.62 CFM under load. The jump is worth it when a system runs quiet at the desktop but must ramp airflow during sustained workloads. Buyers who need PWM signalling, RGB illumination or a longer cable should look elsewhere.

Questions sur cet article

How fast does the Delta Sensflow WFC1212B spin when the thermistor is shorted?

The fan reaches 2447 RPM when the thermistor is shorted, compared to the normal 1245 RPM operating speed.

What is the loudest the fan gets under full load?

Noise rises to 38 dBA at maximum speed, while the minimum is 18 dBA at lower RPM.

Does my motherboard need a specific header for the 2-pin connector?

The fan uses a standard 2-pin interface with a 20 cm lead; 3-pin or MOLEX adapters are available if required.
