OEM Industries FD123010107B 30mm 3-pin CPU cooler

Compact 30 mm CPU cooler for tight builds

The OEM Industries FD123010107B is a 30 mm square fan designed for small-form-factor systems and embedded boards where a full-height tower cooler will not fit. It mounts directly to low-profile heatsinks or tight chassis vents and draws only 0.11 A at 12 V.

3-pin power connector limits speed control

The cooler uses a three-wire 3-pin header that supplies constant 12 V power and reports RPM via the tachometer wire but cannot accept PWM duty-cycle signals. Motherboards that only provide 4-pin PWM headers will run the fan at full speed unless voltage-based control is available.

Suits space-constrained repairs and legacy boards

Builders refreshing older industrial PCs, thin clients or custom enclosures with a 30 mm mounting pattern will find this a direct drop-in replacement. It is not for modern desktop CPUs that require larger heatsink surface area or PWM-regulated airflow.
