Compact 70mm CPU Fan for Tight Builds

The OEM Industries R127020DU is a 70mm square fan designed to mount on low-profile heatsinks in small-form-factor systems. It draws 12V at 0.3A or 0.4A through a standard three-pin connector. The ball-bearing motor and black frame suit replacement or custom cooling loops where height is limited to 20mm.

Bare Fan Unit Requires Existing Heatsink

The package contains only the fan itself — no heatsink, brackets, screws or thermal compound are included. Builders must already own a compatible 70mm mounting pattern or fabricate one. The absence of LEDs keeps the unit visually neutral for professional or industrial chassis.

Simple Three-Pin Swap with Clearance Checks

Installation is a direct plug into any three-pin CPU fan header; no software or adapters are needed. The 20mm thickness demands verification against motherboard component keep-out zones and side-panel clearance. Ball bearings tolerate orientation changes but can develop audible whine over long service intervals.

Questions about this item

How often will the ball-bearing fan in the R127020DU need replacement?

The ball-bearing design is rated for long service life; typical replacement intervals exceed several years of continuous operation.

What thermal limit appears first when the 70mm fan runs at 12V continuously?

The 0.4A current draw at 12V sets the power ceiling; sustained load will hit the motor’s thermal threshold before airflow becomes insufficient.

How much noise and heat does the 70mm fan produce under all-day operation?

At 12V and 0.4A the fan runs at its rated speed, generating moderate airflow noise and minimal case heat rise.
