Delta 3 120x120x38mm PWM case fan

The Delta 3 AFC1212DE HJ1M6-AOO is a 120x120x38mm case fan designed for high-volume airflow. It operates on a 4-wire PWM interface, allowing automatic speed control based on system temperature. The integrated thermostat provides an additional layer of thermal management. This unit is supplied in new condition.

Suited for high-static-pressure cooling needs

This fan suits builders who need substantial airflow through restrictive radiators or dense heatsinks. The 38mm thickness requires adequate clearance in the chassis or mounting bracket. Buyers with slim cases or limited mounting depth should look at thinner alternatives. Those preferring 3-pin voltage control may find the 4-wire PWM connector incompatible with older headers.

Questions about this item

What maintenance will the AFC1212DE HJ1M6-AOO fan need over time?

Periodic dust removal from the blades and frame keeps airflow at its rated level; the sealed bearing is not user-serviceable.

What limit appears first when the fan runs continuously at full PWM duty?

The motor reaches its maximum rated speed and the thermostat regulates power to stay within thermal limits.
