40mm Cooling Fan for Tight Spaces

The OEM Industries AD0412MX-C50 is a 40mm square fan designed for compact CPU coolers or chassis positions where larger units will not fit. It suits builders assembling small-form-factor systems or replacing a noisy original cooler in legacy hardware. The hydro alloy bearing targets quiet, long-life operation in space-constrained builds.

5500 RPM Airflow with 22 dB Acoustic Ceiling

At 12V the fan spins at 5500 RPM with a ten percent tolerance, moving air through dense fin stacks or restricted vents. The rated noise level sits at about 22 dB, so it remains audible but not intrusive in a quiet room. Headroom exists for moderate overclocking; sustained heavy loads on high-TDP processors will exceed its thermal capacity.

Hydro Alloy Bearing Rated for 50000 Hours

The hypro alloy bearing replaces traditional sleeve or ball designs to reduce wear and maintain consistent speed over time. A 50000-hour minimum lifespan translates to years of continuous use without bearing rattle. The two-wire 2-pin connector supplies power only, so speed control depends on voltage regulation from the motherboard or an external controller.

Questions about this item

Will the 40mm fan clear low-profile RAM modules on my existing motherboard?

At 40mm x 40mm x 20mm the unit is a compact fan-only cooler; measure your RAM height against the 20mm thickness to confirm clearance.

How can I verify the 5500 RPM speed is reached after installation?

Connect the 2-pin 12V connector and monitor fan speed in BIOS or hardware monitoring software; the hydro bearing should report approximately 5500 RPM.

Does the package include mounting brackets or thermal paste for CPU installation?

The product is a fan-only unit with a 2-wire 2-pin connector; mounting hardware and thermal compound are not included and must be sourced separately.
