Noctua NH-L9a-AM5, 92 mm Low-profile CPU Cooler, Brown

The NH-L9a-AM5 is a dedicated low-profile CPU cooler engineered for AMD AM5 processors and optimized for integration into small form factor (SFF) chassis. The unit maintains an installed height of 37 mm, facilitating compatibility with highly compact systems, including specialized 1U enclosures. Heat transfer relies on a nickel-plated copper base connected to multiple copper heat pipes and a densely packed array of aluminum cooling fins. This structural configuration prioritizes strict space efficiency while maintaining necessary thermal management capability.

Cooling performance is managed by the included 92 mm NF-A9x14 fan, which utilizes an SSO2 bearing mechanism for operational stability and longevity. The fan operates within a speed range of 600 RPM minimum to 2500 RPM maximum, governed by 4-pin Pulse Width Modulation (PWM) control. Acoustic output peaks at 19.9 dB under high load operation. Furthermore, the cooler's compact footprint ensures guaranteed clearance for system memory and PCIe components across the AM5 motherboard platform.
