Fans 4056 4CM 12V 1.82A Dual Motor Server Case Fan

SKU CH-8VW2-9WXGZ

A 4056 server case fan with dual motors running at 12 V and 1.82 A

  • Dual-motor design for high-static-pressure airflow

40 mm Dual Motor Server Fan

This 4056 form-factor fan runs on 12 V and draws 1.82 A, matching the Delta GFB0412EHS specification for dense server enclosures. It is built for operators who need high static pressure in a 40 mm frame to cool tightly packed blade or 1U chassis.

Installation notes and common issues

The two-wire 12 V connection fits standard 4-pin headers when aligned to the outer pins, but polarity must be observed to avoid damage. The dual-motor assembly is deeper than single-motor 40 mm units, so verify chassis clearance before mounting. No PWM or tachometer wire is present, so speed control and monitoring are not supported.
