SKU CH-P32F-5DV9V

12 V case fan measuring 40 × 56 mm and drawing 1.88 A for high-pressure server cooling

  • Delivers high static pressure for dense 1U server chassis
  • 12 V operation draws 1.88 A for strong airflow
  • Compact 40 mm × 56 mm frame fits tight spaces
  • New AVC 4056 model built for continuous cooling duty

40x56mm 12V server cooling fan

This 4056 form-factor fan fits 1U server chassis and other tight enclosures that require a 40 by 56 millimetre footprint. It runs on 12 volts and draws 1.88 amps to deliver pressurised airflow through restricted channels. The unit is supplied new and targets administrators who need reliable spot cooling for dense rack hardware.

Replaces worn 4056 fans in 1U bays

Swap this in when an existing 40 by 56 millimetre fan becomes noisy, fails or no longer moves enough air through the heatsink stack. The jump is worth it when the chassis cannot accept larger diameters and the 12 volt 1.88 amp power budget matches the original specification. Builders needing higher flow at lower noise or a different voltage should look elsewhere.
