80mm PWM case fan for compact builds

The SXDOOL mf80251v3-1q03c-s9a is an 80mm square fan with a 25mm thickness designed for standard case mounting. It runs on 12V power and draws 1.01W through a 4-pin PWM connector that allows automatic speed control from the motherboard. The unit is supplied new and targets builders fitting cooling into tight chassis or liquid-cooling radiators.

1.01W headroom suits low-restriction airflow

At 1.01W the motor delivers modest static pressure suited to open mesh panels or single-radiator loops. It will struggle against dense fin stacks, multi-radiator stacks or heavily filtered intakes where higher-pressure fans are required. Buyers needing stronger push-through force for restrictive radiators or dust filters should look elsewhere.

Questions about this item

Will the 4-pin PWM interface on this 80mm fan let my older motherboard control its speed automatically?

Yes, the 4-pin connector provides a PWM signal wire so compatible motherboards can adjust fan speed based on temperature without manual intervention.

How can I confirm the fan is running at the correct 12V and 1.01W after installation?

Check the hardware monitoring section in BIOS or use software like HWMonitor to verify the fan reports a speed reading and draws approximately 1.01W on the 12V rail.
