Vszerda DAZB0838RCM 80 mm 4-Pin case fan 13.6 V 0.17 A

Replacement axial fan for AVC systems

The Vszerda DAZB0838RCM is a new 80 mm axial fan built to replace a damaged AVC DAZB0838RCM cooler. It fits CPU cooling assemblies and other equipment that use this exact part number. The four-wire PWM connector allows the host system to regulate speed automatically. Buyers who need a different voltage, frame thickness or connector layout cannot use this unit.

13.6 V 0.17 A input with 8038 frame

The fan draws 0.17 A at 13.6 V DC within an 80 x 80 x 38 mm frame. That power level suits the original AVC design it replaces. Headroom is defined by the host device’s thermal curve; the fan will spin faster or slower as the controller demands. Systems that require higher airflow or a different operating voltage will find the output insufficient.

PWM control matches load in normal use

The 4-pin interface lets the motherboard or controller vary RPM to match the thermal load, so noise and power draw scale with actual demand. At idle the fan runs slower and quieter; under load it speeds up within its 13.6 V limit. No separate speed curve or acoustic rating is published, so exact decibel levels at a given duty cycle are not available.
