The NH-P1, a passive CPU cooler that Noctua introduced in June 2021 for those seeking silent cooling via natural convection, is capable of keeping the Ryzen 9 9950X, AMD’s leading desktop processor based on the Zen 5 architecture, at a temperature of around 95 degrees Celsius, according to a new video with Tony Yu (General Manager, ASUS Computer China) that surfaced today on the Bilibili platform. The CPU, which features 16 cores, 32 threads, and a 170-watt TDP, is shown with a temperature of 95.2°C at one point of the video, while another shot depicts a package power of 225.8 watts. Some viewers have pointed out that this demonstration was performed in a ProArt case that was not only kept open, but had fans running.
“The NH-P1 is our very first passive cooler, and it should be easy to see that we didn’t just take a regular heatsink and omit the fan”, says Roland Mossig (Noctua CEO). “A lot of engineering work went into designing this unit for fanless operation from the ground up and we’re truly proud of the end result. In our completely fanless demo system, the NH-P1 cools an Intel Core i9-11900K running Prime95 at more than 3.6GHz – this is a lot of processing power and a whopping 125W kept in check with zero fan noise!”
