Fans DB04048B12uDimensions 40x40x48mm 12V 1.14A 8800 RPM 25.47 CFM 36.43 mmH2O 59 dBA case fan

SKU CH-HQHD-17CGG MPN DB04048B12uDimensions

A 40×40×48 mm 12 V case fan spins at 8800 RPM to move 25.47 CFM at 36.43 mmH₂O static pressure with 59 dBA noise

  • High airflow of 25.47 CFM cools tight 1U spaces
  • Strong 36.43 mmH2O pressure pushes air through dense heatsinks
  • Ball bearing design supports continuous 8800 RPM operation
  • 12 V 1.14 A input delivers 13.68 W cooling power
  • Compact 40x40x48 mm frame fits slim server chassis

40x40x48mm 12V server fan

The AVC DB04048B12uDimensions is a 40x40x48mm case fan built for 1U server cooling and other space-constrained industrial applications. It runs on 12V DC and draws 1.14A for a rated 13.68W power consumption. Buyers needing larger airflow or quieter operation for desktop towers should look elsewhere.

Sustained high-speed airflow

At 8800 RPM the fan delivers 25.47 CFM of air volume and 36.43 mmH2O of static pressure, figures that are maintained under continuous load rather than only in short bursts. Ball-bearing construction supports this constant high-speed rotation without the wear patterns seen in sleeve-bearing designs. The 59 dBA noise level reflects the steady-state acoustic output during prolonged operation.

Ball-bearing build for tight spaces

The ball bearing and 40x40x48mm frame suit 1U racks, medical devices, rail vehicles and other dense enclosures where vibration resistance matters. A two-wire 12V connection integrates directly into standard server power distributions. No PWM or speed-control header is provided, so the fan runs at full speed whenever powered.

Questions about this item

How loud is the 59 dBA rating when this fan runs continuously in a 1U server?

At 59 dBA the fan is clearly audible, similar to a quiet office conversation, so expect noticeable noise in a small rack or workstation running all day.

What power connector does the 12 V 1.14 A design require?

It draws 13.68 W from a standard 12 V DC supply, so you need a compatible 4-pin or 3-pin header rated for at least 1.14 A.

Will the 40 x 40 x 48 mm frame fit the same mounting holes as my older 40 mm axial fans?

The 40 mm square footprint matches common 40 mm mounts, but the 48 mm depth is thicker than many older models, so verify clearance behind the bracket.
