Koellichaam/radiator Noctua NH-P1 aluminium 158x154x152 mm

The Noctua NH-P1 is a passively designed aluminium CPU heatsink engineered for fanless operation in cases with good natural convection. Measuring 158×154×152 mm and weighing 1.18 kg, its six heatpipes, thick widely spaced fins and soldered fin-to-heatpipe interface provide a robust thermal path for cooling modern high-end CPUs with low to moderate heat dissipation. The package includes the SecuFirm2+ Torx-based multi-socket mounting system and a tube of NT-H2 thermal compound; optional compatibility kits are available for older sockets.

Advantages

The NH-P1 is purpose-built for passive cooling: its fin geometry and mass minimise airflow resistance while maximising heat storage and dissipation for natural convection setups. Soldered fins ensure long-term thermal reliability, the asymmetrical layout improves clearance for the top PCIe x16 slot and the design maintains full RAM compatibility on Intel LGA1851/LGA1700/LGA1200/LGA115x and AMD AM4/AM5 platforms. The included SecuFirm2+ mounting system and NT-H2 thermal paste support reliable installation and optimal thermal contact.

Suitable for

• Fanless desktop builds that prioritise silence and reliability
• Semi-passive systems that use an auxiliary 120 mm fan only under high loads
• Compact ATX and µATX systems where PCIe slot clearance and RAM compatibility matter

How to use

Install the NH-P1 using the included SecuFirm2+ mounting kit and the supplied screwdriver according to the socket-specific instructions. Apply a thin, even layer of the included NT-H2 thermal compound on the CPU heatspreader before fitting the heatsink. Ensure the case provides adequate vertical clearance and natural convection paths (intake/exhaust openings) and verify that the fin-stack does not obstruct the top PCIe x16 slot or tall RAM modules on your motherboard. If additional cooling capacity is required for short spikes or higher TDP processors, mount a low-speed 120 mm fan (for example NF-A12x25 LS-PWM) to operate in semi-passive mode.

Recommendations

Use the NH-P1 in enclosures with good natural convection and unrestricted vertical airflow. For fanless operation choose cases with clear airflow channels and avoid close-fitting shrouds; for semi-passive setups add a low-noise 120 mm fan and configure fan control so fans only spin up under higher CPU loads. Request the optional NM-I3 mounting kit from Noctua if you need compatibility with legacy LGA1366 or LGA775 sockets.
