120 mm 48 V ball-bearing cooler fan

The OEM Industries DB12738B48H P018 is a 120 mm square frame fan built for CPU air coolers that require 48 V operation. It uses a dual ball-bearing design and a four-wire PWM connector for speed control. The unit suits technicians maintaining or assembling server-grade or industrial cooling systems where 48 V rail power is standard.

Check 48 V header and 127 mm mounting

Verify that your motherboard or fan controller provides a 48 V four-pin header; standard 12 V headers will not drive this model. Confirm the mounting pattern matches the 127 mm hole spacing and that the 38 mm frame thickness clears surrounding components. The four-wire lead must reach the header without adapters that could alter voltage delivery.

Fan-only package requires existing heatsink

The box contains only the DB12738B48H fan; no heatsink, brackets or thermal compound are included. You must pair it with a compatible CPU cooler base that accepts a 120 mm fan and supports 48 V PWM control. No software or lighting utilities are bundled because the unit has no LED or addressable lighting features.

Questions about this item

Does the fan ship with mounting screws or a PWM cable, or must they be purchased separately?

The unit is supplied as the fan only; mounting hardware and any additional cables are not included and must be sourced separately.

Should I choose the 48 V 0.47 A ball-bearing version or look for a different voltage or bearing type?

This model is a 48 V, 0.47 A fan with dual ball bearings; select it only if your system provides a 48 V 4-pin header and you prefer ball-bearing longevity over sleeve alternatives.

What does the 120 mm size and 48 V 0.47 A rating mean for airflow and noise once installed in a server chassis?

The 120 mm frame fits standard 127 mm square mounts, and the 48 V 0.47 A input delivers the specified speed and airflow for that form factor; actual noise depends on the PWM curve set by the motherboard or fan controller.
