Noctua NH-L9a-AM4 Extremely Low Noise 37mm High Cooler in Black, suitable for AMD CPUs. PWM controlled Fan Speed possible from 600 RPM to 2500 RPM.

Copper base and heat pipes, aluminimium cooling fins. Second Generation Self-Stabilising Oil-Pressure Bearings. Custom designed SecuFirm2™ mounting system. Highly optimised NF-A9x14 premium fan supporting PWM speed control. Included with NT-H1 thermal compound. 37mm profile: 23mm heatsink + 14mm low profile fan.

NF-A9x14 PWM Premium Fan and Low-Noise Adaptor: Highly optimised fan features Noctua's proprietary AAO frame and sophisticated aerodynamic design measures. Supporting PWM for fully automatic speed control, the NF-A9x14 allows the NH-L9i to stay remarkably quiet. Low-Noise Adaptor included reduces the maximum speed of the NF-A9x14 fan from 1800 to 2500RPM.

RAM and PCI-E Slot Compatibility: The NH-L9ia-AM4 will not cause issues with RAM slots or PCI-E slots.

SecuFirm2™ mounting system: Custom-designed, backplate-less SecuFirm2™ mounting system offers extended compatibility with mini-ITX boards and makes installation easier than ever.

NT-H1 thermal compound: Noctua's much-acclaimed NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and outstanding reliability.

Compatible Motherboards: All AM4 boards and AMD CPUs.

Case Compatibility: The NH-L9ia-AM4 in Black will physically fit in many, but not our entire range of chassis. Please contact us if in doubt.

The M350 and M5X will work if M.2 storage is used instead of 2.5in (this is a recommended combination, don't forget a picoPSU and AC Adapter appropriate for your CPU). Most 'cube' type chassis will work without any problems. CFI NAS chassis (e.g. A7879, A7979) will work. Not compatible with 1U chassis.
