Noctua's first passive CPU cooler NH-P1 was developed from the ground up for fan-less operation: Thanks to six heat pipes and particularly thick cooling fins with Hohem blade spacing, modern high-end processors with low to medium heat dissipation can be cooled passively in housings with good natural convection (see Setup Recommendations and Recommended Housing List). For even higher cooling performance or semi-passive systems where the fans start up only when needed, the NH-P1 can be equipped with a slow, ultra-quiet 120 mm fan such as the NF-A12x25 LS-PWM. Developed from scratch for passive cooling
The NH-P1 is not just a normal heat sink without fan, but was developed from the ground up for fan-less operation. Thanks to significantly thicker cooling fins with especially Hohem blade distance, it achieves both the mass as well as the minimum flow resistance, which are necessary in order to achieve excellent cooling results through natural convection.
Fanless cooling for high-end CPUs
In completely optimized fan-less systems, the NH-P1 can cool modern high-end CPUs with low to moderate heat dissipation by natural convection alone (see Setup recommendations and CPU compatibility list). Thus it is suitable Ideal for powerful systems, which do not require any moving parts and work absolutely silently.
Increased power clearance with additional fans
The NH-P1 can also be equipped with a 120mm fan such as the virtually silent NF-A12x25 LS-PWM to significantly increase maximum cooling performance (see Setup recommendations and CPU compatibility list): Ideal for short peak loads or semi-passive systems whose fans start only when required!
Silent, less dust, 100% fail safe
Fanless cooling has not only the advantage of being completely silent: If Only natural convection is used for ventilation, moreover, less dust accumulates within the system. Without movable parts such as a fan or pump, the NH-P1 is also as fail-safe as a cooler can be!
Asymmetrical design for better PCIe compatibility
Since on many of the latest mainboards the top PCIe x16 slot is very close to the CPU base, it is often blocked by larger coolers. Due to its asymmetric design, the heat sink of the NH-P1 is offset slightly in the direction of the top of the mainboard in the intended installation direction. Thus, the cooler on most current µATX and ATX motherboards does not extend over the top PCIe x16 slot
100% RAM compatibility on LGA1851/LGA1700 and AM4/AM5
Thanks to its asymmetric design, the NH-P1 does not outperform the RAM slots on Intel LGA1851/LGA1700/LGA1200/LGA115x and AMD AM4/AM5 motherboards. SecuFirm2+™ T-profile-based multi-socket mounting system
Noctuas SecuFirm2™ assembly systems have become synonymous with quality, reliability and easy installation. The T-profile-based professional SecuFirm2+™ version including the supplied screwdriver is even more durable and more comfortable to use. Socket support includes Intel LGA1851, LGA1700
Compatibility with older and future sockets
Noctuas SecuFirm2™ Ecosystem makes the NH-P1 compatible with the optional free NM-I3 mounting kit for the older sockets LGA1366 and LGA775. As far as technically possible, Noctua will also offer upgrade sets for future socket - so the NH-P1 is a safe long-term investment!
NT-H2 Heat conductive paste of the next generation
With passive cooling, often every degree counts. For this reason, the NH-P1 is supplied with a tube NT-H2 high-performance heat conductive paste, which is one in comparison to the many times Excellent NT-H1 offers further improved performance and thus enables ideal results with passive cooling.
Soldering of heat pipes and cooling fins
With many coolers the cooling fins and heat pipes are connected by a simple pressing method. Due to the thermal alternating load and the varying expansion coefficients of copper and aluminum, this connection can loosen over the years and WAS leads to loss of power. In the NH-P1, on the other hand, the cooling fins and heat pipes are soldered, WAS enables a better and stable heat transfer over many years.
