Compact 40mm cooler for tight builds

The OEM Industries AD0412HX-C50 is a 40x20mm 12V fan that draws 0.11A. Its hydraulic bearing and two-wire design suit small-form-factor cases, embedded boards or inverter modules where space is at a premium. The square 4cm frame fits standard 40mm mounting holes without protrusion.

Suits low-power CPUs and auxiliary cooling

Builders running low-TDP processors or needing targeted airflow for VRMs, chipsets or industrial enclosures will find this cooler adequate. It is not for high-wattage desktop CPUs, overclocked chips or any workload that demands sustained high static pressure or large heatsink mass.

Two-wire 12V connection simplifies wiring

The fan plugs directly into a 12V header or compatible inverter supply, leaving PWM headers free for other components. No RGB or LED circuitry means no extra cabling. Ensure the mounting pattern matches 40mm hole spacing and that the 20mm height clears surrounding components.

Questions about this item

What power connector does the AD0412HX-C50 need from my system?

It uses a two-wire 12 V connection drawing 0.11 A, so a standard 12 V fan header or compatible supply is required.

Can the 40 mm hydraulic-bearing fan replace a noisier 40 mm sleeve-bearing unit in my existing chassis?

Yes, the 40x20 mm frame matches common 40 mm mounts and the hydraulic bearing typically runs quieter and lasts longer than sleeve types.

How do I confirm the AD0412HX-C50 is spinning correctly after installation?

Check that the fan rotates smoothly at 12 V with no audible grinding and verify RPM in BIOS or monitoring software.
