30 mm 5 V case fan

The SXDOOL DATA0307R5H-002 is a 30 mm circular fan that runs on 5 V power. It fits tight spaces where larger fans cannot be mounted. The black frame carries no LED lighting. It is aimed at builders who need targeted airflow in compact enclosures.

Replaces noisy or failed 30 mm fans

This unit serves as a direct drop-in replacement for worn 3007-size fans in small-form-factor chassis, thin clients or industrial gear. The jump is worth it when the original fan has become loud, has stopped spinning or when a 5 V header is the only power source available. No larger fan can fit the same cut-out.

Check 5 V header and mounting holes

Verify that your board or controller provides a 5 V fan header with the correct pinout for this model. Confirm the 30 mm square mounting pattern matches the existing screw holes. Ensure the 7 mm thickness clears nearby components and cables. Buyers who need PWM speed control or a higher voltage supply should look elsewhere.

Questions about this item

What are the exact mounting dimensions for this 30 mm fan?

The fan measures 30 mm by 30 mm and is 7 mm thick, so it fits any 30 mm mounting pattern with matching hole spacing.

How do I connect the 5 V power lead correctly?

Plug the two-pin connector into a 5 V fan header or a 5 V USB header, observing the red-positive and black-negative polarity marked on the housing.

Which part wears out first and when should I plan a replacement?

The sleeve bearing is the only moving part; expect to swap the fan when audible whirring appears or airflow feels reduced.
