ADDA 40 mm Hydraulic Fan

The ADDA AD0412HX-G70 is a 40 mm square fan with a hydraulic bearing and a 2‑pin 12 V power connector. It draws 0.1 A and is finished in black with no LED lighting. The unit is supplied as a fan only, intended for compact CPU cooling or similar tight‑space airflow tasks.

Builders with 40 mm mounting holes

This cooler suits systems that have a 40 mm fan mount and need a low‑profile hydraulic bearing fan. It is not for builds that require a larger fan frame, a PWM‑controlled header or any form of RGB illumination. Buyers who need higher static pressure from a bigger frame should look at a different size.

40 mm hydraulic bearing with 2‑pin power

The decisive specification is the 40 mm frame combined with a hydraulic bearing and a 2‑pin 12 V connector. If your motherboard or heatsink only accepts a 40 mm two‑pin fan, this model matches; if the mount or header differs, the fan will not fit or function.

Questions about this item

Should I choose the 12 V 0.1 A version or a different voltage?

The AD0412HX-G70 is a 12 V 0.1 A fan; match it to a 12 V header on your board.

What does the 40 mm size mean for airflow in my case?

A 40 mm hydraulic fan fits tight spaces but moves less air than larger coolers.

What does the 2-pin connector limit in practice?

The 2-pin connector runs at full speed constantly with no PWM control.
