Fans DELTA 12032 48V 0.33A 120mm 4000RPM case fan

SKU CH-B16G-CA2X6

120 mm case fan moves 200 CFM at 4000 RPM using a 48 V, 0.33 A ball-bearing motor rated for 80,000 hours at 25 °C

  • 200 CFM airflow driven by 4000 RPM speed
  • 48 V DC input with 28.0–53.4 V operating range
  • 80,000-hour rated life at 25 °C ambient
  • PBT frame and blades with 30 % glass fibre and VO flame retardant
  • High-precision ball bearing for durable rotation

Industrial-grade 48 V 120 mm fan

This 120 mm case fan operates on a 48 V DC supply with a working range of 28.0 to 53.4 V and draws 0.33 A at 16 W. It spins at 4000 RPM to deliver 200 CFM or 5.7 cubic metres of airflow through a 32 mm thick frame rated for -40 °C to +70 °C operation. The unit uses a high-precision ball bearing and meets a 500 V insulation test.

Voltage and mounting constraints

The fan requires a 48 V DC source capable of maintaining voltage within the 28.0 to 53.4 V window; standard 12 V or 24 V headers cannot drive it. Its 120 x 120 x 32 mm dimensions and four-wire lead demand a mounting pattern and connector that match this exact footprint and pinout. The 42-piece bulk packaging means no individual retail box or accessories are included.

Compatibility checks before ordering

Verify that your chassis or equipment provides a 48 V DC rail with sufficient current headroom for 0.33 A per fan. Confirm the 120 mm mounting holes align with the 32 mm depth and that the four-wire connector matches your controller pin assignment. Ensure the operating environment stays within the -40 °C to +70 °C range for the rated 80,000-hour life at 25 °C ambient.

Questions about this item

Which DELTA 12032 variant should I pick for a 48 V system?

The supplier lists a single 48 V, 0.33 A, 4000 RPM model with 16 W power draw and 200 CFM airflow, so there is no capacity choice to make.

What does 200 CFM mean once the fan is installed?

It moves 5.7 cubic metres of air per minute at 4000 RPM, delivering strong directional cooling through a 120 mm frame in a live chassis.

How does the four-wire PWM interface limit control?

The four-wire lead enables PWM speed regulation between 28.0 V and 53.4 V, capping maximum RPM at 4000 while allowing lower speeds for quieter operation.
