Compatible Replacement Fan

This 4-pin CPU cooling fan is designed as a direct replacement for HP Omen 15-ax series laptops including the 15-ax000, 15-ax100 and 15-ax200 models. It is a new component intended for repair or maintenance when the original cooler fails or becomes noisy. The package includes a single fan unit ready for installation.

Four Pin Power Interface

The fan connects via a standard 4-pin PWM header on the laptop motherboard, allowing the system to control speed based on processor temperature. Buyers must verify that their original fan uses the same 4-pin connector and identical voltage specification before ordering. Different production batches may carry varying labels while remaining electrically compatible.

Single Fan Cooling Capacity

With one fan installed, the unit handles thermal loads for the supported Omen 15-ax chassis under normal operating conditions. It is not suitable for laptops outside the listed model range or for systems requiring dual-fan configurations. Users with heavily overclocked processors or restricted airflow may find the cooling headroom insufficient.
