Compact Centrifugal Blower

The SunnyStar A34123-57 is a 12 V, 0.46 A centrifugal blower built for tight enclosures. Its 97 × 97 × 33 mm housing fits 100 mm mounting points while the blower wheel directs airflow across heatsinks or through restricted ducts. A three-pin connector provides simple voltage control. Ball-bearing construction supports continuous operation in industrial or custom PC builds.

Suited for directed airflow in small chassis

This blower suits builders who need focused exhaust from a 33 mm deep slot, such as small-form-factor cases, GPU shrouds or rack appliances. The fixed three-pin header works with basic voltage regulation but offers no PWM signal for automatic speed curves. Buyers who require four-pin speed control or a slimmer profile should consider other designs.

33 mm frame depth

The 33 mm thickness is the critical dimension that determines whether the A34123-57 fits your bracket or duct. Measure the available clearance before ordering, as the blower cannot be installed in spaces sized for thinner fans. The 97 mm square footprint aligns with standard 100 mm screw holes.

Questions about this item

What comes with the SunnyStar A34123-57 blower fan and is anything else needed?

The fan ships as a single 97*97*33 mm centrifugal blower with a 3-pin power connector. No screws, adapters or controllers are included, so you will need mounting hardware and a 3-pin header on your board or a separate fan controller.

Which version of the A34123-57 should I choose for my build?

Only one version is listed: 12 V, 0.46 A, 3-wire 3-pin, 100 mm frame, ball bearing, non-LED black housing. Choose this model when you need a 10 cm centrifugal blower with those exact electrical and physical specs.

What does the 0.46 A rating mean once the fan is installed?

At 12 V the blower draws 0.46 A, giving a modest power draw that most motherboard 3-pin headers or standard fan controllers can supply without extra cabling.
