Compact 40mm ADDA cooler

The OEM Industries AD0412LB-G76 is a 40mm square fan with a 10mm thickness designed for targeted CPU cooling. It operates on 12V power drawing 0.07A through a standard three-pin connector. The ball-bearing construction supports continuous operation in compact chassis or industrial enclosures. No LED lighting is included.

Replaces larger low-profile coolers

This fan-only unit upgrades from bulkier heatsink assemblies where vertical clearance is below 10mm or mounting holes match a 40mm pattern. The jump is worth it when a full cooler blocks adjacent components or exceeds the thermal budget of a small-form-factor board. Builders needing higher static pressure or PWM control should look elsewhere.

Fits tight 40mm mounts

The 40x10mm frame aligns with standard 40mm mounting holes and requires a three-pin header supplying 12V. It frees up vertical space around the socket for tall memory modules or voltage-regulator heatsinks. The three-wire connection provides tachometer feedback for BIOS monitoring without needing a four-pin PWM header.

Perguntas sobre este artigo

What are the exact mounting dimensions for the AD0412LB-G76 cooler?

The cooler measures 40mm square and 10mm thick, matching the standard 4010 footprint for direct screw mounting.

How do I connect the 3-pin power connector correctly?

Align the guide tab on the 3-pin plug with the motherboard header notch; forcing it backwards bends pins and prevents speed reporting.

When should I plan to replace the ball-bearing fan?

Ball bearings typically run for years; replace the unit when noise increases or RPM drops below spec under 12V 0.07A load.
