SXDOOL

SXDOOL AFB0812SH 80mm 12V 0.51A 4-pin PWM case fan

SKU CH-NFZN-FCX1V

An 80 mm PWM case fan delivering 46.6 CFM airflow at 4000 RPM with 40 dB(A) noise and dual ball bearing

  • 40 dB(A) quiet operation at 4000 RPM
  • 6 CFM airflow cools components efficiently
  • 267 in H₂O static pressure suits restrictive spaces
  • Dual ball bearing rated 70000 hrs at 40°C
  • 4-pin PWM enables automatic speed control

Compact 80 mm PWM Cooling

The SXDOOL AFB0812SH is an 80 mm tubeaxial fan built for PC chassis cooling. It runs on 12 V DC and draws a rated 0.51 A through a 4-pin PWM connector. The dual ball bearing is rated for 70000 hours at 40 °C, making it suitable for continuous operation in workstations or servers.

Practical Interface Limits

The fan accepts a voltage range of 7 to 13 V DC and uses a standard 4-pin PWM header for speed control. At full speed it spins at 4000 RPM and produces 40 dB(A) of noise. The 4-pin connector allows motherboard-based fan curves, but the motor itself does not support voltage ranges outside the stated 7 to 13 V window.

Airflow and Pressure Decide Fit

This model delivers 46.6 CFM (1.32 m³/min) of airflow with a static pressure of 0.267 in H₂O (66.5 Pa). Builders who need higher static pressure for dense radiators or restrictive filters will find this fan insufficient. It is intended for general case ventilation where moderate airflow and long bearing life are the priorities.

Highlights

  • 6 CFM airflow cools components efficiently
  • 267 in H₂O static pressure suits restrictive spaces
  • Dual ball bearing rated 70000 hrs at 40°C
  • 4-pin PWM enables automatic speed control

Questions about this item

Should I pick the 12V 0.51A version or a lower-voltage model for my chassis?

This fan is rated for 12V DC with a 0.51A current draw, so choose it when your fan header or controller supplies 12V; lower-voltage models would not match that header.

What does the 4000 RPM rating mean once the fan is installed in my case?

At full PWM duty the fan spins at 4000 RPM, moving 46.6 CFM of air with 0.267 in H2O static pressure while producing 40 dB(A) of noise.

How does the 4-pin PWM interface control the fan and what does it cap in practice?

The 4-pin PWM connection lets the motherboard vary speed from idle up to the 4000 RPM maximum, so the header's PWM signal caps the top speed and the minimum is set by the board's fan curve.
