Compact 40 mm 5 V server fan

The EFB0405LD-ROO 4020 is a 40 mm square frame fan that runs on 5 V at 0.16 A. Dual ball bearings provide reliable rotation for continuous duty in network switches and dense server chassis. Its 20 mm thickness matches the Delta form factor used in many 1U appliances.

Fits tight 40 mm mounts

The fan slots into any 40 mm square cutout with standard screw spacing, drawing power from a 5 V header or molex adapter. Low current leaves headroom on limited 5 V rails, while the ball-bearing design reduces maintenance cycles in always-on equipment.

Questions about this item

What is the current draw at full speed?

The fan draws 0.16 A at 5 V, which is the maximum electrical load it places on the power rail under sustained operation.

How much acoustic and thermal output should I expect in continuous use?

With dual ball bearings and a 40 × 40 × 20 mm frame, the unit runs steadily at its rated voltage, producing only the airflow noise and waste heat inherent to that power level.
