OEM Industries 80mm 24V Cooling Fan

The OEM Industries L34690-57 is an 80mm square cooling fan manufactured by NIDEC. It operates at 24V with a 0.11A current draw and uses a three-wire connection. The fan features ball bearings and has no LED lighting. It is sold as a fan-only unit in black.

Suitable for 24V three-wire fan headers

This fan suits builds or replacement jobs that specifically require a 24V 80mm unit with a three-wire interface and ball-bearing construction. It is not intended for systems that provide a different voltage header or a two-wire or four-wire connector. Buyers needing a larger frame size, integrated lighting or a different bearing type should consider other options.

24V 0.11A three-wire electrical interface

The decisive specification is the 24V 0.11A three-wire electrical interface. The cooler will only function correctly when connected to a header that supplies exactly that voltage and pin arrangement. Verify the motherboard or controller documentation matches these values before purchase.

Questions about this item

What power supply or header provides 24 V and .11 A for this fan?

A 24 V source capable of at least .11 A is required; the three-wire connector fits headers wired for that voltage.

Will the 80 mm frame and 25 mm depth fit the same mounting holes as my existing 8025 cooler?

Yes, the 80 mm square frame and 25 mm thickness match the standard 8025 footprint used by many coolers.

How can I confirm the ball-bearing fan is spinning at the correct speed after installation?

The third wire carries a tachometer signal; connect it to a monitoring header and verify RPM in BIOS or software.
