Noctua nh-p1: passive cpu cooler with 1.2 kg weight

Noctua has presented the first own passive CPU-Kuhler. The NH-P1 relies on particularly thick chill lamellae with a coarse distance to let the emergence boom upwards by convection. Among other things, the model is suitable for AMD’s AM4 and Intel’s LGA1200 platforms, but not every processor achieves its full boost clock frequencies with the CPU cooler. With a slowly rotating 120 mm air, the cooling capacity can be increased optionally.

Due to the massive aluminum slats, the NH-P1 weighs more than 1.2 kilograms more than the Double Tower Kuhlkorper of Noctuas Top Model NH-D15 (1 kg without air; 1,3 kg with two airs). In principle, the cooling capacity is only with a fraction.

Eight-core coolable

Since the cooling performance of housing is significantly different from housing, Noctua does not give a thermal design power (TDP) in Watt with its own CPU-Kuhuhler. Instead, the manufacturer averages the performance with the help of multiple test scenarios. In "Noctuas Standardized Performance Rating" (NSPS) creates the NH-P1 42 points and thus less than the Kuhlerwinzling NH-L9I (from 39.87 €) with air (59 points). The NH-D15 (from € 84.41) creates 183 points.

The NH-P1 is therefore a niche product for completely silent desktop PCs or possible quiet semi-passive systems. According to Noctua, the model in the right environment but quite Intel’s Rocket Lake Top Model Core i9-11900K can cow with a continuous power consumption of 125 watts, which should hold its base clock frequency of 3.5 GHz.

Hause recommendations

In an overview, Noctua recommends a variety of housing for combining with the NH-P1, which can either allow an outrage of the Aberme upwards or have good active volume by an open structure. In a second list, Noctua leads on how the CPU cooler behaves in conjunction with popular processors. AMDS Ryzen-9-CPUs run at standard TDP from 105 watts (142 watt real power consumption).

The list also includes entries for operation with the 120mm air NF-A12x25 LS-PWM. This is a parallel, slowly rotating version of the NF-A12x25 with speeds of circa 450 to 1200 rpm, which can be applied by means of brackets at the top of the NH-P1 and increases the cooling capacity at low rushors. At 0 percent PWM signal, the rotor turns off so that a semi-passive operation is possible.

The CPU Kuhler NH-P1 costs 110 euros, the air NF-A12x25 LS-PWM 30 Euro. Both are already in Germany.
