Fans case fan AVC DB04028B12H P154 12V .53A 4-pin 80mm 40x40x28mm

Compact 80 mm PWM fan for tight builds

This 40 × 40 × 28 mm fan fits the 80 mm mounting pattern while drawing only 0.53 A at 12 V. The 4-pin connector enables motherboard speed control so the cooler responds to actual temperature rather than running at a fixed rate. It suits small-form-factor cases, rack appliances or GPU shrouds where a full-size 80 mm frame would not clear. Buyers needing higher static pressure for dense radiators or larger airflow for big towers should look elsewhere.

Steady 12 V operation under continuous load

Rated for 0.53 A at 12 V DC, the motor maintains its speed curve without thermal throttling during extended sessions. The 4-wire PWM interface lets the system ramp the fan only as far as the load demands, keeping acoustic output proportional to cooling need. No additional controller or adapter is required for standard 4-pin headers. Builds that rely on 5 V or 3-pin voltage regulation will not achieve the same granular control.
