Compact 40 mm cooling fan

The OEM Industries 4020H24S ND1 is a 40 mm square fan designed for tight chassis where a low-profile CPU air cooler is required. It runs on 24 V DC at 0.11 A through a two-wire connection and uses a ball bearing for durable rotation. The black frame fits standard 40 mm mounting holes in industrial or embedded systems.

Replaces larger or sleeve-bearing units

This fan suits builds that previously used thicker coolers or sleeve-bearing fans which wore out under continuous duty. The jump is worth it when space is limited to a 40 mm footprint and a 24 V supply is already present. It is not for builders who need higher airflow than a 40 mm frame can deliver or who require PWM speed control.

Steady airflow under constant load

Ball-bearing construction maintains consistent speed during sustained operation without the friction increase seen in sleeve alternatives. The two-wire design provides fixed-voltage running suited to always-on environments such as servers or industrial controllers. No LED lighting means no extra current draw or light bleed in dark racks.

Pitanja o ovom artiklu

What are the mounting hole dimensions for the 40mm square frame?

The fan uses a standard 40mm square frame with mounting holes spaced for that size; verify your heatsink or case uses the same 40mm hole pattern before fitting.

How do I connect the two-wire lead to a 24V DC source correctly?

Connect the red wire to positive and the black wire to negative on a 24V DC supply; reversing polarity will prevent the ball-bearing motor from starting.

When should I expect to replace the ball-bearing fan?

Ball bearings typically run for years at 0.11A load; replace the unit if rotor noise increases or airflow drops noticeably.
