Square black 80 mm PWM case fan with clear blades and short four-wire cable

Fans

Fans PFC0812DESize 80×80×38mm 12V 3.30A 152.06CFM 4-wire PWM case fan

SKU CH-BYMR-5DMC3 MPN PFC0812DESize

An 80 mm PWM case fan delivering 152.06 CFM at 12 V and 3.30 A with a ball bearing rated for 10.0000 hours at 25 °C

  • 06 CFM airflow for rapid heat removal
  • 4-wire PWM control matches speed to thermal load
  • 30 A current rating supports sustained high output
  • Ball bearing rated 10.0000 hours at 25 °C
  • PBT frame with 30 % glass fibre and VO flame retardant

High-airflow 80 mm PWM fan

The Delta PFC0812DE is an 80 × 80 × 38 mm axial fan built for systems that need maximum airflow in a compact frame. It suits industrial equipment, dense server chassis or workstations where space is limited but cooling demand is high. The four-wire PWM connector allows motherboard speed control via a standard 4-pin header. Buyers who need a quieter, lower-flow fan for a silent desktop should look elsewhere.

Thermals and power at normal speed

At the rated 12 V the fan draws 3.30 A and consumes 39.6 W while delivering 152.06 CFM. The PBT frame and blades with 30 % glass fibre and VO flame retardant withstand operating temperatures from -10 °C to +70 °C. A high-precision ball bearing keeps friction low, and insulation resistance exceeds 500 megohms at 500 V withstand voltage. The 10 cm cable reaches most nearby headers without strain.

Sustained-load behaviour

Continuous operation at 25 °C ambient is rated for 10.0000 hours before bearing wear becomes significant. The design tolerates a ±15 % supply variation without loss of function. Counter-clockwise rotation (viewed from the blade side) pushes air through heat exchangers efficiently even during prolonged high-duty cycles. Storage extremes of -40 °C to +70 °C ensure the unit survives transport and off-season conditions.

Questions about this item

How do I install the 80 × 80 × 38 mm case fan and what is the common mistake?

Mount the fan using the four corner holes with the airflow arrow pointing in the desired direction; the mistake is plugging the 10 cm 4-pin PWM connector into a 3-pin header, which disables speed control.

What maintenance or replacement will the high-precision ball bearing need later?

The bearing is sealed and rated for 10.0000 hours at 25 °C; after that period the fan should be replaced rather than relubricated.

At what temperature does the 39.6 W fan hit its thermal limit during sustained use?

The operating ceiling is 70 °C; running continuously at or above that temperature will trigger the limit first.
