120 mm 3-wire case fan
This 120 mm case fan runs on 12 V DC and draws 0.6 A for a rated power of 7.2 W. Its frame measures 120 mm square and 38 mm thick, and it connects via a standard three-wire lead for basic speed monitoring.
Builders wanting PWM control or a thinner frame
The three-wire interface does not support PWM speed regulation, so systems that require four-pin control cannot adjust fan speed automatically. The 38 mm thickness also prevents installation in chassis or heatsinks limited to slimmer fans.

- Delivers strong airflow for effective case cooling
- Runs on standard 12V DC power with 7.2W draw

Questions about this item
Will the 120 mm frame and 38 mm depth fit the same mounting holes as my existing 12038 fan?
Yes, the 120 mm square frame and 38 mm thickness match the standard 12038 mounting pattern used by most cases and radiators.
How can I confirm the 3-wire connection is reporting speed correctly in BIOS?
The third wire carries a tachometer signal; enter BIOS hardware monitor and verify the RPM reading changes when the fan spins up.
