Product information

Description

The Noctua NH-L12Sx77 is a compact low-profile CPU heatsink with a 120mm slim fan that balances strong cooling performance and compatibility for small form factor (SFF) builds. At 77mm height and featuring six heatpipes, it delivers improved thermal headroom compared with the original NH-L12S while maintaining the fan-under-fin-stack orientation to exhaust hot air directly through perforated case panels. The package includes the NF-A12x15 slim 120mm PWM fan (450–1850 RPM), Noctua’s NT-H2 thermal compound, SecuFirm2™ multi-socket mounting system and compatibility options for a wide range of Intel and AMD sockets, plus a 6-year manufacturer’s warranty.

Advantages

The NH-L12Sx77 offers enhanced cooling capacity thanks to six heatpipes and a high-efficiency NF-A12x15 slim fan, while remaining compact enough for many SFF/SFX cases. Its fan-under-fin orientation helps exhaust hot air directly and reduces intake turbulence noise. Soldered fins ensure long-term thermal contact, and the included NT-H2 compound and SecuFirm2™ mounting system simplify installation and improve thermal performance. The cooler supports both default low-profile and high-clearance configurations to accommodate tall RAM or chipset coolers.

Suitable for

  • Small form factor (SFF/SFX) builds with limited height (cases like Fractal Design Terra, SilverStone Milo ML12, Louqe Raw S1)
  • Compact desktops that need better cooling for high-performance CPUs with aggressive turbo modes
  • Systems requiring improved motherboard and RAM clearance (up to 44mm in default orientation, up to 56mm in high-clearance mode)
  • Users who want a quiet PWM-controlled 120mm slim fan with LNA option

Key specifications

  • Model: Noctua NH-L12Sx77 (MPN: NH-L12Sx77, EAN: 9010018000504)
  • Dimensions (W×D×H): 128 × 131 × 77 mm (default configuration)
  • Fan: NF-A12x15 slim 120mm PWM (450–1850 RPM, Low-Noise Adaptor reduces max to 1400 RPM)
  • Airflow / noise: 94.2 m³/h / 23.9 dB (manufacturer data)
  • Heatpipes: 6 heatpipes, soldered fins
  • RAM clearance: 44 mm (standard), up to 56 mm in high-clearance mode
  • Socket support: Intel LGA1851, LGA1700, LGA1200, LGA115x; AMD AM5, AM4. Optional free upgrade kits available for older sockets (LGA20xx, LGA1366, LGA775) where applicable
  • Included: NF-A12x15 fan, SecuFirm2™ mounting, NT-H2 thermal compound, Low-Noise Adaptor, fan clips for 25mm fans
  • Warranty: 6 years

How to use

Install the NH-L12Sx77 using the supplied SecuFirm2™ mounting kit following the motherboard-specific instructions included in the package. Apply a thin, even layer of the supplied NT-H2 thermal compound to the CPU heatspreader before seating the heatsink. The fan is pre-installed underneath the fin stack for exhaust airflow; optionally move the fan on top of the fins to enable high-clearance mode or replace it with a 25mm 120mm fan for increased performance (this increases overall cooler height to 102mm). Connect the fan to a motherboard PWM header to allow automatic speed control.

Usage recommendations

Use the default fan-under-fin orientation in compact cases with perforated panels above the CPU to exhaust hot air directly. Switch to high-clearance mode (fan on top) if you need extra clearance for tall RAM modules or chipset coolers. Use the Low-Noise Adaptor to limit maximum fan speed when quieter idle operation is preferred.
