Dual Fan Replacement Kit

This two-fan kit replaces both the CPU and GPU coolers in compatible ASUS ROG Zephyrus M15 GX502 and GU502 series laptops. It addresses worn or noisy original fans that can cause thermal throttling or system errors. The set includes parts matching multiple manufacturer part numbers for precise fitment. Installers should verify the exact model code before fitting.

Sustained Thermal Performance

Each fan runs on DC 12 V at 1 A through a 4-pin 4-wire connector, providing continuous airflow to both processor and graphics chip. Replacing aged units restores the laptop’s ability to maintain stable temperatures during extended workloads. The design targets fast cooling with low acoustic output for a quieter operating environment. Proper installation ensures the system no longer flags fan-speed errors.

Installation Guidance

The package contains two separate fans intended for the specific GX502 and GU502 chassis variants listed in the compatibility data. Fitment requires opening the laptop and disconnecting the original 4-pin connectors before securing the replacements. Common issues arise when the part number or physical layout does not match the exact sub-model, so careful visual comparison is essential. No additional hardware or adapters are included.
