OEM Industries AB7305HX-GB3 CWZQ5 5V .5A 3-Pin Blower CPU cooler

Replacement Blower for Notebook Servicing

This OEM Industries blower is a direct-fit replacement fan for notebook cooling assemblies that require the ADDA AB7305HX-GB3 CWZQ5 specification. It suits repair technicians and owners performing out-of-warranty maintenance on compatible laptops. The three-wire, three-pin connector delivers tachometer feedback to the system controller. No LED lighting is included.

Upgrading from a Failed or Noisy Original

The unit replaces a worn, rattling or non-spinning factory blower that can no longer maintain safe component temperatures. The jump is worth it when the original bearing has degraded or the fan has stopped entirely, causing thermal throttling or unexpected shutdowns. Hydraulic bearing construction aims to reduce friction noise compared to aged sleeve-bearing units. Compatibility must be verified against the laptop service manual before purchase.

Sustained Airflow in Confined Chassis

Under continuous load the blower maintains a steady 5 V, 0.5 A draw while exhausting heat through the notebook’s existing ducting. Hydraulic bearing lubrication is designed to sustain consistent rotational speed without the rpm decay common in dry bearings. The three-pin header allows the embedded controller to modulate speed in response to prolonged thermal demand. Performance scales with the laptop’s own thermal firmware rather than an external curve.
