Noctua

The Noctua NH-L9a-AM4 is a quiet premium cooler designed for AMD-based HTPCs and small form factor systems. With an ultra-slim height of just 37 mm, the NH-L9a-AM4 is ideal for particularly compact cases. Thanks to its footprint of 92 x 114 mm, the cooler offers excellent compatibility with tall memory modules and other components on mini-ITX motherboards. The custom SecuFirm2 mounting system for AM4 makes installation a breeze. The highly optimized NF-A9x14 premium fan with PWM support for automatic speed control provides outstanding operational quietness. With the included low-noise adapter, the speed of the NF-A9x14 fan can be reduced from 2,500 RPM to 1,800 RPM. This allows for nearly silent systems with CPUs under 65 watts TDP. The package is completed with Noctua's renowned NT-H1 thermal paste. The NH-L9a combines all the advantages of larger Noctua coolers in an extremely compact, high-quality complete package for slim HTPC systems.

Key specifications

Socket

A CPU socket or CPU slot is a mechanical component that provides mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows the CPU to be replaced without soldering.
Common sockets have retention clips that apply a constant force, which must be overcome when a device is inserted. For chips with a large number of pins, either zero-insertion force (ZIF) sockets or land grid array (LGA) sockets are used instead. These designs apply a compression force once either a handle (for ZIF type) or a surface plate (LGA type) is put into place. This provides superior mechanical retention while avoiding the risk of bending pins when inserting the chip into the socket.

Max. TDP

The thermal design power (TDP), sometimes called thermal design point, refers to the maximum amount of power the cooling system in a computer is required to dissipate. For example, a laptop's CPU cooling system may be designed for a 20 watt TDP, which means that it can dissipate up to 20 watts of heat without exceeding the maximum junction temperature for the computer chip. It can do this using an active cooling method such as a fan or any of the three passive cooling methods, convection, thermal radiation or conduction. Typically, a combination of methods is used. The TDP is typically not the most power the chip could ever draw, such as by a power virus, but rather the maximum power that it would draw when running "real applications". This ensures the computer will be able to handle essentially all applications without exceeding its thermal envelope, or requiring a cooling system for the maximum theoretical power (which would cost more but in favor of extra headroom for processing power).

Airflow

The air volume refers to the amount of air that can be moved or circulated per unit of time. It is often measured in cubic metres per hour or litres per second. A higher air volume generally indicates a stronger suction force or circulation of air.
