Black 80mm square frame fan with 4-pin PWM connector

Fans

Fans EFC0812DBAppearance 80mm 4000 RPM PWM case fan

SKU CH-FFCX-1BYDB MPN EFC0812DBAppearance

An 80 mm PWM case fan delivering 26.7–32.97 CFM at 4000 RPM with 28 dBA noise and 60,000-hour ball-bearing life

  • 4-pin PWM enables automatic speed control
  • 4000 RPM delivers strong airflow for cooling
  • 28 dBA keeps operating noise low
  • Ball bearing rated for 60000 hours life
  • 80 mm frame fits standard case mounts

Compact 80 mm PWM Fan for Tight Builds

The Delta EFC0812DBAppearance is an 80 mm axial case fan spinning at 4000 RPM with a four-pin PWM interface. It suits small-form-factor cases, rack servers or CPU cooler replacements where mounting depth is limited to 15 mm and motherboard speed control is required.

PWM Control Range and Airflow Ceiling

The fan draws 0.50 A at 12 V and delivers between 26.7 and 32.97 CFM depending on duty cycle. PWM lets the board vary speed down from 4000 RPM, but the curve stops at that ceiling; systems needing more static pressure or silence at idle will hit the hardware limit.

Simple Four-Pin Install with Ball-Bearing Care

The standard 4-pin header plugs directly into any compatible motherboard socket and reports speed via the third wire. Ball bearings give a 60,000-hour rating, yet the bulk pack ships without screws or anti-vibration mounts, so installers must supply their own hardware and avoid over-tightening the thin frame.

이 상품에 대한 질문

Which version of the Delta EFC0812DBAppearance 80mm fan should I choose for CPU replacement versus chassis intake?

The same EFC0812DBAppearance model serves both roles; its 4000 RPM PWM control and 26.7–32.97 CFM range suit CPU cooler replacement and case airflow alike.

What does the 4000 RPM headline speed deliver once the fan is installed in a system?

At 4000 ± 10% RPM the fan moves 26.7–32.97 CFM at 28 ± 3 dBA, giving strong airflow for heat-exchanger or chassis cooling while PWM adjusts speed to load.

How does the standard 4-pin PWM interface limit or enable control in practice?

The 4-pin motherboard header supplies 12 V at 0.50 A and carries the PWM signal, so the board can vary speed from minimum to 4000 RPM and read back the tachometer for monitoring.
