Compact 40 mm Cooling Fan

The YINGHUA AD0412HX-K96 is a 40 mm square case fan with a 6 mm thin profile. It runs on 12 V and draws 0.08 A through a three-pin connector with a 4 cm lead. The unit weighs 9 g and is sold new.

Suited For Tight Spaces

This fan suits builds that need airflow in very small enclosures such as 1U servers, mini-ITX cases or industrial chassis. It is not for users who require higher static pressure or greater air volume than 5.9 CFM at 27.0 dBA.

6300 RPM Operating Speed

The decisive specification is the 6300 RPM rotational speed, which determines the 5.9 CFM airflow and 0.079 inH₂O pressure. Match this speed to your thermal target before purchasing.

Questions about this item

Will the 40 mm by 6 mm frame and 4 cm cable reach my motherboard header?

The fan measures 40 mm square by 6 mm thick and ships with a 4 cm three-pin lead, so it fits tight 40 mm mounts but the short cable may need an extension.

How do I connect the three-pin plug without losing speed control?

Plug the original small 3P connector into a 12 V three-pin or four-pin header; the third wire reports 6300 RPM but voltage control depends on the board, not the fan.

When should I plan to replace the sleeve bearing in this 6300 RPM fan?

At 27.0 dBA and 0.08 A the sleeve bearing runs quietly, but high-speed sleeve fans typically need replacement after two to three years of continuous use.
