Verify HP Part Numbers and Form Factor Fit

Before ordering, confirm your system requires one of the listed HP part numbers: 656362-B21, 643931-001, 660184-001, or 643954-101. Ensure the chassis accepts a standard ATX form factor unit and that the connector layout matches your motherboard requirements. This unit is intended for G6, G7 and G8 generation hardware identified by the 380 and 388 series references. Cross-reference your service manual to guarantee mechanical and electrical compatibility.

Zero RPM Fan Mode Enables Silent Low-Load Operation

The bundled cooling intelligence includes a Zero RPM fan mode that stops the fan completely at low and medium loads. This provides near-silent operation during idle or light tasks without any software configuration. The Resonant LLC topology further reduces acoustic noise by suppressing coil whine. These features combine to lower ambient noise and support energy-efficient sleep states for a quieter computing environment.
