Delta AUC0812D 80mm ball-bearing fan

The Delta AUC0812D is an 80mm square frame fan with ball-bearing construction, rated for 12V and 0.70A. It uses a three-pin power connector and a four-wire lead approximately 7 cm long. The black frame measures 80 by 80 by 25 mm. It is supplied as a fan only, without LEDs, for system integrators or repair technicians who need a direct replacement unit.

Check your header and clearance before ordering

Verify that your motherboard or controller provides a three-pin header, because the fan ships with a three-pin connector despite the four-wire lead shown in the supplier image. Confirm the mounting holes match an 80mm square pattern and that 25 mm thickness fits inside your chassis or heatsink shroud. Ensure the 12V 0.70A draw is within the header’s current limit. Buyers who need PWM speed control via a four-pin header cannot use this model.

Replaces worn 8025 ball-bearing fans

This unit replaces a failed or noisy 8025-size ball-bearing fan in CPU air coolers, server enclosures or industrial equipment where the original carried the same 12V 0.70A rating. The jump is worth it when the existing fan has developed bearing rattle, reduced airflow or complete stoppage. It does not upgrade airflow beyond the original specification, so builders seeking higher static pressure or lower noise should not select this part.

Questions about this item

Does the AUC0812D come with mounting screws or a PWM cable, or must I buy them separately?

The box contains the 80 mm ball-bearing fan with a 3-pin power connector and about 7 cm of lead wire; mounting hardware and any 4-pin adapter are not included.

Should I choose the 12 V 0.70 A ball-bearing version or look for a different bearing type?

The listed model uses a ball bearing at 12 V and 0.70 A; no other bearing or voltage variants are offered for this AUC0812D.

What does the 0.70 A rating mean for airflow and noise once the fan is installed in my case?

At 12 V the fan draws 0.70 A, giving high-speed cooling for an 80 mm frame with noticeable but not extreme noise under load.
