Black 80mm square case fan with transparent blades and 3-wire lead

Vszerda

Vszerda DA08025B12UR 80x80x25mm 12V 0.50A 4800RPM case fan

SKU CH-5G4B-MEDDZ MPN DA08025B12UR

An 80 mm square frame 25 mm thick spins at 4800 RPM on a 12 V double-ball bearing with a three-wire lead

  • High airflow at 4800 RPM for effective cooling
  • Double ball bearing reduces maintenance needs
  • 12 V 0.50 A draws 6 W of power
  • Standard 80 mm square fits common chassis mounts
  • Three-wire lead provides speed monitoring capability

Compact 80 mm case fan

The Vszerda DA08025B12UR is an 80 x 80 x 25 mm frame fan that runs on 12 V and draws 0.50 A. Its double ball bearing is rated for maintenance-free operation at a constant 4800 RPM. A three-wire lead provides power and a stall alarm signal for system monitoring.

Suits tight chassis and server bays

Builders working in 1U racks, small-form-factor cases or inverter enclosures gain a high-speed airflow option that fits the 8025 mounting pattern. The single fixed speed and 3-wire connector make it unsuitable for PWM-controlled quiet builds or for anyone who needs variable fan curves.

4800 RPM fixed speed

The fan spins at 4800 RPM from the moment power is applied, delivering maximum airflow without any speed regulation. If your thermal design requires adjustable RPM or a lower noise floor, this model will not meet that requirement.

Jautājumi par šo preci

How does the 3-wire lead interface limit speed control?

The three-wire lead supplies power, ground and a tachometer signal but lacks a PWM wire, so the motherboard can only adjust voltage for coarse speed changes.

What are the exact frame dimensions and mounting-hole spacing?

The frame is 80 mm by 80 mm and 25 mm deep; mounting holes follow the standard 80 mm fan pattern used in chassis and server brackets.

How do you install the fan and what common mistake should be avoided?

Align the four corners with the case or server bracket, screw in using the 80 mm hole pattern, then connect the 3-wire lead to a 3-pin or 4-pin header — do not force the connector onto a 2-pin header.
