Compact 30 mm system fan

The SXDOOL AFB0312HA is a 30 mm square case fan built for tight spaces such as small-form-factor PCs, notebooks or embedded appliances. It runs on a standard 12 V supply and draws only 0.15 A, making it suitable for low-power thermal management.

Dual ball-bearing 3-pin connector

A dual ball-bearing assembly supports a rated continuous operation of 10 000 hours while keeping acoustic output low. The three-pin motherboard interface delivers a speed signal so the system can monitor fan health without PWM control.

Fixed-voltage 12 V operation

Because the unit operates at a fixed 12 V with no PWM input, speed cannot be modulated by the motherboard; airflow remains constant regardless of thermal load. Builders who need variable-speed cooling or larger airflow volumes should consider alternative solutions.

Questions about this item

Does the 3-pin connector allow the motherboard to monitor the fan speed?

Yes, the three-pin interface includes a speed-signal wire so the board can read RPM.

Will this 30 mm × 10 mm frame fit the fan slot on my notebook or small-form-factor chassis?

The fan measures 30 mm square by 10 mm thick, matching the standard 3010 mounting holes.

How do I connect the fan so the speed signal works correctly?

Plug the 3-pin header onto the motherboard fan connector aligning the key; the third wire then reports RPM to the BIOS.
