We don’t have a ton of passive coolers on the market anymore, but I’m glad we have this one. The tolerances are tight, it’s easy to install, and it works much better than I expected.
I’m running a 5800x3D in the same case as a 3080 ti. This isn’t the coldest running system, but this cooler has kept my cpu under 65 C while under load. I do have two Noctua fans in the front of my case that provide a small amount of airflow, but that seems to be more than enough in side of my NZXT 510. This case is notoriously bad with air flow, but this cooler handles it like a champ.
Keep in mind that higher end chips with higher TDP will require a tower that has some sort of active airflow. If you’re looking at purchasing this cooler you should already know how to set your fan curves accordingly.
If you plan on using this in tandem with a totally passive build proceed with caution when dealing with any cpu that has a TDP higher than 100 watts. It will run well for a while, but you will fall out of boost clocks when the cooler gets heat soaked.
I’m a big fan of this cooler, because I can set my fan curve to keep my fans off under most light to moderate loads. This also has the added benefit of no moving parts. No fan to go bad, no pump to clog, and no water levels to maintain. I will be long gone before this cooler goes through enough heat/cooling cycles have an effect on performance.

Noctua Cooling Solutions
Noctua's premium cooling components are internationally renowned for their superb quietness, exceptional performance and quality.
Product Description
The NH-P1 is Noctua’s first passive CPU cooler and has been custom-designed for fanless operation from the ground up: in enclosures with good natural convection, its six heatpipes and thick, widely spaced heatsink fins enable it to cool modern high-end CPUs with low to moderate heat dissipation completely passively (see setup guidelines and list of recommended cases). For further enhanced performance or semi-passive setups that only spin up their fans when necessary, the NH-P1 can be outfitted with a low-speed, ultra-quiet 120mm fan such as the NF-A12x25 LS-PWM. Topped off with the professional Torx-based SecuFirm2+ mounting system and Noctua’s award-winning NT-H2 thermal compound, the NH-P1 is the ideal cornerstone for premium-grade fanless or semi-passive builds.
Designed for passive cooling from the ground up
The NH-P1 isn’t just a regular heatsink without a fan: it has been designed for fanless operation from the ground up, featuring much thicker, much more widely spaced fins in order to achieve both the mass and the minimal airflow resistance that are required in order to excel in natural convection cooling.

|---|---|---|---|
No noise, less dust, 100% fail-proofFanless cooling doesn’t only have the advantage of being completely silent: if you’re relying on natural convection only and don’t have case fans pushing air through a case, less dust will accumulate in filters or inside the system. Last but not least, with no moving parts such as fans or pumps that could possibly fail, the NH-P1 is as fail-proof as it can be. |
100% RAM compatibility on LGA1851/LGA1700 and AM4/AM5Due to its asymmetric design, the NH-P1 does not overhang the RAM slots on Intel LGA1851/LGA1700/LGA1200/LGA115x and AMD AM4/AM5 based motherboards, which ensures easy access to the modules and 100% compatibility with DIMMs that feature tall heat-spreaders. |
Asymmetrical layout for optimal PCIe compatibilityAs many current motherboards have the top PCIe x16 slot sitting close to the socket, bigger heatsinks tend to block it. Due to its asymmetrical layout, the fin-stack of the NH-P1 is offset towards the upper edge of the motherboard when installed in standard orientation. This allows it to clear the top PCIe x16 slot on most current µATX and ATX motherboards (see motherboard compatibility list). |
SecuFirm2+ Torx-based multi-socket mounting systemNoctua’s SecuFirm2 mounting systems have become synonymous with quality, safety and easy installation. Torx-based, the professional SecuFirm2+ version with its included screwdriver provides even better handling and durability. Socket support includes Intel LGA1851, LGA1700 (since 2021), LGA1200 and LGA115x (LGA1150, LGA1151, LGA1155, LGA1156), as well as AMD AM4 and AM5. |
Increased performance headroom with extra fan
The NH-P1 can be fitted with an extra 120mm fan such as the near inaudible NF-A12x25 LS-PWM in order to increase its maximum dissipation capacity significantly: ideal for short spikes of higher heat loads or semi-passive systems that only start their fans when necessary!

Shipped with everything needed for installation. Once I installed on my Ryzen 5 1600 CPU I was able to get an overclock of 3.9 GHz easily with temps under a cinebench load hovering around the low 60s Celsius. I have since upgraded to a newer intel I3 10105F CPU, and temps under a typical gaming load have yet to exceed 60 degrees C! My case is a be quiet silent base 802 in the airflow configuration. As long as you have a larger case, mid or full size towers, with decent airflow I think this cooler will be very effective. I also have three be quiet 120 mm case fans always turning inside case, but all are tuned to stay at very low rpm generating little noise from two feet away. Also I know noctua doesn’t recommend my case for this cooler, but I think their estimates of what this can cool are very conservative. Great cooler just a little pricey as a more niche product.

Die Umrüstung ging relativ einfach, dank der sehr guten, dem Kühlkörper beiliegenden, Beschreibung.
Es war nicht ganz leicht, das Motherboard aus dem PC auszubauen. Das ist notwendig, um die rückseitige Montageplatte des Kühlers zu installieren. Das Gewicht mit > 1KG schon enorm für so einen kleinen PC.
Trotz sommerlicher Temperaturen liegt die Temperatur der CPU zwischen 43° und 53°.
Im Büro herrscht jetzt wohltuende Ruhe! :-) und ich frage mich, warum in den Kühlkörper nicht schon viel eher gekauft habe. Sollte ich mir mal einen anderen PC zulegen, kann ich den Kühlkörper auf ganz viele verschiedene CPUś motieren - das Geld ist also langfristig sehr gut angelegt.
Mein Fazit ist eine klare Kaufempfehlung!

je voulais un PC 100%Inaudible car je suis hyper sensible aux bruits de ventillateurs.
Il a donc demandé un choix éclairé des composants.
Le site de Noctua est d'ailleurs un modèle du genre pour la compatibilité.
J'ai choisi pour faire un pc 100% passif :
+un ryzen 5600G pour se passer de carte graphique
+une alimentation corsair RM750x semi passive .En dessous de 350w elle est passive et la configuration tire au max 160W, j'ai de la marge
+Un boitier Fractal Meshify 2 Compact car conseillé par Noctua en conf 100% passive.
+Une CM B550 avec de bon radiateurs sur les VRM (Gigabyte Elite v2)
+Ram Corsair LPX 3600C18 car la moins cher vitesse/prix.
Montage parfaitement documenté comme souvent avec Noctua
Le NH-P1 a une comptabilité à 100% pour la RAM sur un socket AM4 car il ne couvre aucunement la RAM (voir photo)
Résultat le CPU est à ~35° en iddle et 42° dans un jeu pas trop lourd.
Le cpu monte à 70° au bout d'une boucle de cinebench R23 et redescend gentiment esuite.
Un OCCT à 100% CPU/GPU le met un peu à mal (mais c'est normal il est pas prévu pour).
Le cpu monte doucement à 95° (au bout de plus de 20 minutes de burn) et baisse légèrement de fréquence. Mais ça se stabilise. C'était attendu.
J'ai ajouté un ventilo au dessus pour sortir la chaleur du boitier. Résultat même à 30-40% ventilo inaudible et CPU à 82° max.
J'ai donc programmé le ventilateur pour se déclencher au dessus de 70° CPU et à l'arrêt sinon.
J'obtient un pc 100% silencieux, avec des composant standards (pas de minipc, mini itx ou autre) qui sera donc évolutif avec des cpu de tdp de 65w ou moins.
Merci Noctua pour ce produit atypique mais qui correspond bien à mon besoin.
