NOCTUA NH-P1 Passive CPU Radiator 6 Heat Pipes Support Dual Platform Fanless NH-P1 Passive Radiator 6 Years Warranty

Noctua NH-P1

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.

Fanless cooling for high-end CPUs

In fully optimised fanless systems, the NH-P1 is capable of cooling high-end CPUs with low to moderate heat dissipation using natural convection only (see setup guidelines and CPU compatibility list). This makes it ideal for powerful builds that have no moving parts and run absolutely silent.

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 (see setup guidelines and CPU compatibility list): ideal for short spikes of higher heat loads or semi-passive systems that only start their fans when necessary!

No noise, less dust, 100% fail-proof

Fanless 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.

Asymmetrical layout for optimal PCIe compatibility

As 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 motherboards compatibility list).
