Compact 70 mm CPU cooler

The OEM Industries PF70251VX-Q000-S99 is a square 70 mm fan designed for CPU cooling in space-constrained builds. It uses a maglev bearing and a 4-pin PWM connector for automatic speed control. No LED lighting is included. The unit draws 3.7 W at 12 V.

Sustained-load behaviour

Maglev bearings reduce friction so the fan maintains consistent airflow during extended workloads without the wear that affects sleeve designs. The 4-wire interface lets the motherboard adjust RPM in real time as temperatures rise. Power draw stays at 3.7 W under continuous operation.

Compatibility checklist

Verify that your CPU socket mounting holes accept a 70 mm square frame and that a 4-pin fan header is available on the motherboard. Confirm the chassis has at least 25 mm clearance above the socket for the fan thickness. Buyers needing larger heatsink surface area or liquid-cooling integration should consider other solutions.

Questions about this item

How much power does the 12 V 3.7 W fan draw when running continuously?

The fan is rated at 3.7 W at 12 V, so continuous operation draws that amount from the motherboard header.

Does the 4-pin PWM connector work straight from a standard CPU fan header?

Yes, the 4-pin connector plugs directly into a standard motherboard CPU fan header for power and speed control.

Will the 70 mm square frame fit alongside taller memory modules on an older board?

The 70 mm square footprint is compact, leaving clearance for most memory modules on legacy motherboards.
