Compact 70mm CPU Fan

The OEM Industries D07R-12B2M is a 70mm cooling fan designed for CPU and case applications. It operates on a 12V supply drawing 0.12A and uses a 3-pin power connector. The unit features a 2-ball bearing design for reliable rotation and contains no LED lighting.

Replaces Worn 70mm Units

This fan serves as a direct replacement for failed or noisy 70mm coolers using the same voltage and connector. The jump is worth it when the original bearing has degraded or airflow has become insufficient for the thermal load. It is not suited for builds requiring larger fan diameters or PWM speed control via a 4-pin header.

Simple 3-Pin Installation

Installation involves mounting the 70mm frame into the existing bracket and connecting the 3-pin header to the motherboard. The 3-wire lead provides tachometer feedback for speed monitoring. Ensure the mounting holes align with the 70mm spacing and that the header key matches the board connector to avoid bent pins.

Questions about this item

What size mounting holes does the 70mm frame use?

The fan has a 70mm square frame; standard 70mm mounting-hole spacing applies.

How do I connect the 3-pin connector so the motherboard reads speed?

Align the guide tab on the 3-pin plug with the header notch; the third wire carries the tachometer signal.

When should I replace the 2-ball bearing assembly?

Replace the fan if bearing noise appears or rotor speed drops below specification.
