Noctua NH-P1 Passive CPU Cooler 158 mm 1185g

Fanless Heatsink for Silent Builds

The Noctua NH-P1 is a passive CPU cooler designed for 100% silent operation through natural convection. It targets builders who want zero fan noise and reduced dust accumulation in compatible enclosures. The six heatpipes and widely spaced fins provide the mass and low airflow resistance needed for fanless cooling. It suits CPUs with low to moderate heat dissipation such as Intel 285K, 265K, 245K or AMD Ryzen 7900, 7700, 7600.

Upgrade from Active Air Coolers

This cooler replaces traditional tower coolers that rely on attached fans for heat dissipation. The jump is worth it when the build prioritises absolute silence over maximum thermal headroom and the case appears on Noctua's recommended list for natural convection. It also works in semi-passive setups with an optional NF-A12x25 LS-PWM 120mm fan that only spins up when necessary. Builders needing to cool high-TDP processors under sustained loads should stay with active cooling.

Torx SecuFirm2+ Mounting System

Installation uses the professional Torx-based SecuFirm2+ mounting kit supplied for Intel LGA1851, LGA1700, LGA1200, LGA115x and AMD AM5, AM4 sockets. The design guarantees 100% RAM compatibility on AM4 and LGA1700/1200 platforms and clears the top PCIe slot on most ATX and µATX motherboards. NT-H2 thermal compound is included for optimal contact. The 158 mm height and 1185g weight require a case with sufficient clearance and a motherboard with adequate mounting reinforcement.
