Fans AFC1212DEDELL 12038 12V 1.6A 4000RPM 154.5CFM 45.4dB case fan

SKU CH-XHFM-QXEAB MPN AFC1212DEDELL

A 12 V PWM case fan spinning at 4000 RPM to deliver 154.5 CFM at 45.4 dB with a double ball bearing and PBT glass-fibre frame

  • PWM speed control via 4-wire lead
  • 5 CFM airflow for demanding cooling
  • 4000 RPM maximum rotational speed
  • Double ball bearing for long life
  • VO-rated PBT frame with 30% glass fibre

High-Airflow PWM Case Fan

The Delta AFC1212DEDELL is a 12038 form-factor case fan built for systems that demand high-volume air movement. It runs on 12 V DC at 1.60 A and spins at 4000 RPM to deliver 154.5 CFM. The four-wire PWM lead allows speed control through the motherboard, while the double ball bearing supports continuous operation in demanding environments. The frame uses PBT with 30 percent glass fibre rated VO for flame resistance.

Suited for High-Static-Pressure Cooling

This fan targets builders cooling dense radiators, server chassis or industrial enclosures where raw airflow outweighs acoustic comfort. At 45.4 dB-A the noise level is significant, so it is not a fit for quiet home or office PCs. Buyers who need silent operation or lower power draw should look at lower-speed alternatives. The one-piece injection-moulded frame ensures structural rigidity under vibration.

4000 RPM Speed Decides Fit

The fixed maximum speed of 4000 RPM is the critical specification that determines whether this fan matches your thermal design. It drives both the 154.5 CFM airflow and the 45.4 dB-A noise figure. Verify that your fan header can supply 1.60 A at 12 V and that your chassis can accommodate the 12038 footprint before purchasing.

Questions about this item

Which version of the AFC1212DEDELL should I choose for PWM speed control?

The model listed has a four-wire lead that supports PWM, so this single version already provides temperature-controlled speed regulation.

What does the 154.5 CFM airflow figure mean once the fan is installed in a case?

At 4000 RPM the fan moves 154.5 CFM, delivering very high air volume through a 120 mm frame for demanding cooling loads.

What interface does the fan use and what does it cap in practice?

The four-wire PWM connection lets the motherboard vary speed up to the 4000 RPM maximum, capping both airflow at 154.5 CFM and noise at 45.4 dB-A.
