Noctua NH-P1, Passive CPU Cooler, Silver

The Noctua NH-P1 is engineered as a dedicated passive CPU cooler, operating without required active fans to deliver completely silent thermal performance. This specialized design is optimized for PC builds utilizing wide-open cases or those with strong natural convection currents. Heat dissipation relies on six heavy-duty heatpipes that transfer thermal energy from the copper base plate to an array of widely spaced aluminum fins. The increased fin spacing maximizes effectiveness under low airflow conditions inherent to fanless operation.

Installation utilizes the included SecuFirm2+ mounting system, ensuring secure attachment across modern Intel LGA1851, LGA1700, and AMD AM5/AM4 sockets. The unit’s substantial weight of 1180 grams and total height of 152mm require verification of case structural integrity and component clearance prior to installation. While designed for zero-fan usage, the NH-P1 includes clips that permit the optional addition of a 120mm cooling fan for semi-passive setups or environments with higher thermal loads.
