Ultra-Compact 30 mm 5 V PWM Fan

The SXDOOL ASB0305HP-00 is a 30 x 30 x 7 mm DC brushless fan that runs on a 5 V supply and connects through a standard 4-pin PWM header. It targets system integrators and hobbyists who need active cooling in extremely tight spaces such as small-form-factor PCs, embedded appliances or GPU VRM heatsinks.

Ideal for Tight Clearances.

This unit suits builders who must fit a fan into a 30 mm square footprint and who can power it from a 5 V rail with PWM speed control. It is not suited for anyone who needs higher airflow or static pressure than the 4.34 to 5.1 CFM range this miniature frame can deliver.

4-Pin PWM Control at 5 Volts

The four-wire interface allows the motherboard or controller to regulate speed between roughly 7 000 and 9 500 RPM while drawing a maximum of 0.50 A at 5 V. That single connector and voltage combination determines whether the fan can be used in a given header or power budget.

Questions about this item

How do I choose the right fan for my 30 mm mounting space?

This model fits a 30 × 30 × 7 mm cut-out and draws 5 V DC at up to 0.50 A, so match those dimensions and the 5 V header on your board.

What does the 9 500 RPM rating mean for everyday cooling?

At full speed the fan spins at 9 500 RPM and pushes between 4.34 and 5.1 CFM, delivering targeted airflow for tight spaces like GPU heatsinks or small-form-factor cases.

What does the 4-pin connector actually control?

The fourth wire carries a PWM signal that lets the motherboard vary speed between the minimum and the 9 500 RPM maximum while reporting real-time RPM back to the system.
