Specific 40×56 mm form factor

This 40 mm by 56 mm case fan fits the exact mounting pattern required by the DL140 G2 and DL145 G2 chassis. It serves as a direct replacement for part numbers 389107-002 and 408285-001. Builders working on those specific platforms will find the physical dimensions match without modification.

Continuous 12 V operation

The unit runs on a 12 V DC supply drawing 1.88 A through a six-wire, four-pin connector. That electrical profile supports steady airflow for CPU-cooler duty cycles rather than short bursts. The non-LED black frame keeps the visual profile neutral inside the enclosure.

Proprietary six-wire pinout

The four-pin connector carries six wires in a layout unique to the DF04056B12U 030 series. Compatibility is limited to the listed DL140 G2 and DL145 G2 models; other four-pin headers will not match the wiring scheme. Buyers needing a standard PWM fan for a generic motherboard header should look elsewhere.

Questions about this item

Does the 1.88 A rating on the 12 V line mean the 40x56 mm fan runs hot when it spins all day?

The DF04056B12U draws 1.88 A at 12 V, so sustained load stays within the header’s design envelope without extra cooling.

What must my motherboard provide to run this 4-pin 12 V cooler fan?

A standard 4-pin PWM header supplying 12 V at up to 1.88 A is all that is required.

Will the 40x56 mm frame fit the DL140G2 and DL145G2 coolers I already own?

Yes — the DF04056B12U 030 is built as a direct replacement for the 389107-002 and 408285-001 fans used on those models.
