Compact 30 mm DC blower fan

This AYAGROUP 4020S-DC-FAN measures 30 mm square and 20 mm thick. It runs on 12 V DC at 0.1 A and spins between 6000 and 6499 RPM. A 2-pin connector with 7-inch leads supplies power. The brushless motor uses a ball bearing and thermoplastic UL94V-0 PBT blades.

Suited for tight exhaust or heatsink spots

Builders fitting a small-form-factor chassis, a GPU heatsink shroud or a rack-mount appliance will appreciate the focused airflow. The single 2-pin header offers no PWM control, so systems needing variable speed or motherboard fan curves should look elsewhere. Buyers who want a larger frame or quieter acoustics will need a different fan.

Simple two-wire installation

Connect the 2-pin plug to a 12 V header or molex adapter; polarity is the only check required. The short 7-inch cable may not reach distant headers in full-size towers, so plan routing or add an extension. Vibration can appear if the four mounting holes are not all secured on a flat surface.

Questions about this item

Does the 4020S-DC-FAN need a 2-pin 12 V header on my motherboard or controller?

Yes, it uses a 2-pin connector rated for 12 V DC and 0.1 A, so a matching 12 V header or adapter is required.

Will the 30 mm, 6000–6499 RPM blower fit in the same 40×40×20 mm cut-out as my old 40 mm fan?

No, the frame is 30 mm square and 20 mm thick, so it will not align with a 40 mm mounting pattern.

How can I confirm the 4020S-DC-FAN is running at its specified speed after installation?

Check the fan RPM in BIOS or monitoring software; it should read between 6000 and 6499 RPM, and noise should be around 23 dBA.
