Compact 3-pin CPU cooler for notebooks

The OEM Industries AD3605HX-QB3 is a circular cooling fan built for notebook and laptop thermal management. It runs on a 5 V 0.3 A supply through a standard 3-pin connector. The hydraulic bearing supports smooth rotation with reduced friction. No LED lighting is included, keeping the unit suited to professional or low-profile builds.

Replaces worn original fans when noise

This cooler serves as a direct swap for a failing ADDA AD3605HX-QB3 or equivalent 3-wire module. The jump is worth it when the original bearing becomes audible or RPM becomes unstable under load. It restores the factory cooling curve without requiring a motherboard header change. Buyers who need PWM speed control or a 4-pin header will not find that here.

Hydraulic bearing steadies output during long

Under sustained load the hydraulic bearing maintains consistent speed better than sleeve alternatives. The 5 V 0.3 A draw stays constant, so thermal throttling is less likely to spike unexpectedly. Airflow remains stable across extended compile, render or gaming periods. The 3-pin connection reports speed but does not regulate voltage dynamically.

Questions about this item

What motherboard header does the 3-pin connector on the AD3605HX-QB3 plug into?

The 3-pin power connector fits a standard 3-pin or 4-pin CPU fan header on the motherboard; align the guide tab so the yellow sense wire sits on the correct pin.

Which way does the airflow travel through the AD3605HX-QB3 when the blades spin clockwise?

With clockwise rotation the fan blows air toward the motor side, so mount it with the label facing the heatsink if you want air pushed through the fins.

How often should the hydraulic bearing in the AD3605HX-QB3 be checked for noise or wear?

Hydraulic bearings are sealed and maintenance-free; listen for rattling after the first 24 hours of use and replace the fan only if noise develops.
