Ruth's sister internal power cable 12V 0.50A 80x80x25mm 4-pin PWM

SKU CH-VWP3-VJBMC

An 80 mm 12 V PWM cooling fan measuring 80 by 80 by 25 mm with a 0.50 A draw

  • 12 V 0.50 A power draw keeps energy use low
  • 80 mm square frame fits standard 80 mm mounting points
  • 25 mm thickness suits slim chassis builds
  • 4-pin PWM header enables automatic speed control

80 mm 12 V PWM cooling fan

The DA08025B12UH is a square-frame fan measuring 80 by 80 by 25 millimetres. It runs on 12 volts direct current and draws 0.50 amperes. The four-pin PWM connector allows the motherboard to regulate speed automatically. Builders fitting compact cases or replacing a noisy stock cooler can use this unit as a direct drop-in.

Thermals noise and power draw

At 12 volts the fan consumes six watts of electrical power. PWM control lowers the rotational speed when thermal load is light, reducing audible noise. Under full load the motor maintains steady airflow through the 80-millimetre frame. The design suits systems where a single 80 mm mount must balance cooling capacity with quiet operation.

  • 12 V 0.50 A power draw keeps energy use low
  • 80 mm square frame fits standard 80 mm mounting points
  • 25 mm thickness suits slim chassis builds
  • 4-pin PWM header enables automatic speed control

Questions about this item

How do I install the 80x80x25mm 4-pin PWM fan and what step is often missed?

Mount the fan using the four 80 mm screw holes, connect the 4-pin PWM header to the motherboard, and set the fan curve in BIOS so the 0.50 A motor runs at the correct speed.

What maintenance will the 12 V 0.50 A 8025 fan need later?

Clean dust from the blades and frame every few months with compressed air; the sealed bearing is not user-serviceable, so replace the unit if noise or vibration appears.
