Cooler Specification
Caution: while the NH-P1 provides first-rate performance for a passive cooler, it is not suitable for overclocking or CPUs that create high heat loads.
Please note that the TDP (Thermal Design Power) rating or amount of heat dissipation that the cooler can handle not only depends on the chassis and various other factors such as ambient temperature or other components inside the system, but also generally varies from CPU model to CPU model. For this reason, we specify cooling performance using the Noctua Standardised Performance Rating (NSPR) instead of giving a general TDP specification. In addition, we refer to our CPU compatibility list where we indicate how well the cooler can be expected to work on a particular CPU in a fully optimised setup (see our setup guidelines).
Please also note that the NH-P1 strictly requires either a fanless PC case with good natural convection, an open benchtable-type setup or a PC case with fans in order to achieve its full performance. We offer a list of recommended cases for completely fanless systems using the NH-P1. If necessary, Noctua recommends adding a near-inaudible 120mm fan like the NF-A12x25 LS-PWM to the heatsink for improved performance headroom.
Since the NH-A12x25 LS-PWM fan is recommended to keep silence and additional airflow, then we will also include tests with this fan in our review. Below you can find photos of this separated product. As always, there is a full set with mounting elements and adapters.
Having received more than 100 awards and recommendations from international hardware websites and magazines, Noctua’s flagship model NF-A12x25 has established itself as a true deluxe choice when it comes to premium-quality quiet 120mm fans. Various state-of-the-art technologies and a record tight tip clearance of only 0.5mm, which is made possible by using the novel Sterrox® liquid-crystal polymer material, allow it to achieve superb results in all types of usage: Whether it’s in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, pressure-demanding scenarios such as on heatsinks and watercooling radiators, the NF-A12x25 is a proven winner. The 4-pin LS-PWM version is a low-speed, PWM-enabled variant that is ideal for semi-passive setups or ultra-low-noise applications that require near-silent acoustics and PWM based speed control. Topped off with exceptional running smoothness, Noctua’s reference-class SSO2 bearing, a rich bundle of accessories and 6-year manufacturer’s warranty, the NF-A12x25 is a premium-quality product through and through. Its superior efficiency, cutting-edge construction and pioneering materials make it an elite choice for the most discerning demands.
On the next page, we will look at the NH-P1 cooler itself.
