Product identity and audience

The Thinkstar 120 mm case fan is a 12 V DC brushless cooler rated at 0.45 A with a three-pin connector. It fits standard 120 by 120 by 25 mm mounting points and is intended for system builders who need a direct replacement for the Delta WFB1212H or WFB1212H-R00 models.

Practical limits of the 3-pin interface

A three-pin connection supplies constant 12 V power and a tachometer signal but lacks pulse-width modulation control. Fan speed therefore varies only with voltage changes from the motherboard header, so the unit runs at a fixed maximum unless the board supports voltage regulation. Builders who require automatic temperature curves should verify header capabilities before purchase.

Installation notes and common issues

The fan installs with four screws into any 120 mm frame and plugs into a standard three-pin header. Polarity is fixed by the keyed connector, so incorrect insertion is unlikely. The most frequent issue is cable reach in larger chassis; extensions may be needed if the header sits far from the mount point.

Questions about this item

Should I pick the 0.45 A model or a different current rating?

The listing specifies a single 0.45 A version; choose this model if your fan header can supply at least 0.45 A at 12 V.

What does the 0.45 A rating mean once the fan is installed?

At 12 V the fan will draw up to 0.45 A, so the header must deliver that current continuously for reliable start-up and speed control.

How does the 3-pin connector limit control options?

The 3-pin interface supports voltage-based speed control only; PWM duty-cycle control is not available on this connector.
