Genuine Jianzhun 120 mm 24 V case fan

This Genuine Jianzhun 12038 fan measures 120 by 120 by 38 mm and runs on 24 V power. It draws 0.38 A for a rated 9.2 W and spins at 3100 RPM. The unit delivers 138 CFM of airflow for demanding cooling tasks.

Suited for 24 V industrial or server chassis

Builders working with 24 V systems in servers or industrial enclosures will match the voltage and 12038 form factor. Buyers who need a 12 V fan for a standard desktop PC cannot use this model. Those requiring PWM speed control or a different mounting pattern should look elsewhere.

24 V operating voltage is the deciding spec

The fan operates only on a 24 V supply, so the chassis or controller must provide that exact voltage. A 12 V header will not run the motor and a higher voltage risks damage. Confirm the system delivers 24 V before purchase.

Questions about this item

Will the 24 V 120 x 120 mm frame fit my existing 24 V fan headers?

The fan runs on 24 V and draws 0.38 A, so it matches any 24 V header rated for at least 9.2 W.

How can I confirm the fan is delivering the rated 138 CFM at 3100 RPM after installation?

Use a tachometer or motherboard monitoring to verify 3100 RPM; airflow will then meet the 138 CFM specification.

Does the box include mounting screws or a PWM cable, or must I buy them separately?

The package contains only the 120 x 120 x 38 mm fan; screws and any required cables are sold separately.
