About DBTB0428B2U 4cm 4028 40x40x28mm DC12V 0.48A 4 lines server power supply large air volume cooling fan
What is DBTB0428B2U 4cm 4028 40x40x28mm DC12V 0.48A 4 lines server power supply large air volume cooling fan?
This unit is a 4 cm square, 40 × 40 × 28 mm centrifugal fan designed for DC12 V operation at 0.48 A. It delivers a large volume of air through four output lines, making it suitable for dense server power-supply enclosures where space is limited but cooling demand is high. Constructed from durable polymer housing and stainless-steel blades, the fan provides reliable, low-noise airflow for 24-hour operation.
Key features
- Compact footprint — 40 × 40 × 28 mm size fits tight rack spaces.
- DC12 V, 0.48 A — Direct-current power matches common server supplies.
- Four output lines — Distributes airflow across multiple components.
- High air volume — Moves enough air to lower component temperatures.
- Durable polymer housing — Resists heat and vibration.
Who is DBTB0428B2U 4cm 4028 40x40x28mm DC12V 0.48A 4 lines server power supply large air volume cooling fan for?
IT professionals, data-center technicians, and hobbyist builders who need a reliable, space-saving cooling solution for server power supplies, networking switches, or compact industrial controllers will benefit from this fan.
How does DBTB0428B2U 4cm 4028 40x40x28mm DC12V 0.48A 4 lines server power supply large air volume cooling fan compare?
Compared with generic 12 V rack fans, this model offers a four-line airflow design that spreads cooling more evenly across multiple heat sources, while maintaining a smaller physical profile and lower power draw than larger, multi-speed fans.
Best use cases
- →Cooling dense server power-supply modules
- →Ventilating network switch chassis
- →Keeping industrial controller boxes cool
- →Supplemental airflow in compact NAS enclosures
Is DBTB0428B2U 4cm 4028 40x40x28mm DC12V 0.48A 4 lines server power supply large air volume cooling fan right for you?
Choose this fan if you manage small-form-factor server racks or networking gear that runs on DC12 V and needs consistent airflow without adding bulk. It suits users comfortable with basic hardware installation; no advanced fan-control software is required. For higher airflow or variable speed, consider larger rack fans or PWM-controlled models.
How it compares: Unlike single-output rack fans, this four-line design spreads air across multiple components, offering more uniform cooling while staying smaller than typical 80 mm fans. It fills the niche between tiny clip-on fans and larger, variable-speed rack units.

What size enclosure can accommodate this fan?
▾
The fan measures 40 × 40 × 28 mm, so it fits standard 1U or 2U rack units that have a 4 cm square mounting area, making it ideal for tight server or networking enclosures.
Does the fan support variable speed control?
▾
No, the DBTB0428B2U operates at a fixed speed designed for DC12 V input. It provides consistent airflow without the need for PWM or voltage-adjustable control.
How much airflow does the fan move?
▾
While exact CFM is not published, the fan’s four-line configuration is engineered to move a large volume of air relative to its size, sufficient to lower temperatures of typical server power supplies.
Is the fan compatible with non-DC12 V systems?
▾
The fan is rated specifically for DC12 V operation at 0.48 A. Using it with other voltages could damage the unit or reduce performance, so it should only be paired with compatible power supplies.
Can this fan be used in a home lab setup?
▾
Yes, hobbyists building home labs often need compact cooling for small server boards or networking gear, and this fan’s size and voltage make it a practical choice for such projects.
