"Noctua’s NH-P1 is a unique fanless cooler that offers completely silent performance, at the cost of slightly reduced cooling power. You won’t look at this if you need every last bit of performance for overclocking, but rather if you’re a user who prefers quiet and has more common workloads. Even if you do run intense multi-core workloads, there won’t be much of a performance loss – as shown with our Cinebench R23 tests using AMD’s Ryzen 9 9950X3D.
At this time, not only is Noctua’s NH-P1 the strongest fanless solution available for common users – it is also the only one that is easily available for purchase. The $119 USD price tag might be difficult to swallow, but that’s the price of a niche product with strong performance."
