Noctua NH-L12Sx77 77mm Low Profile CPU Cooler NF-A12x15 PWM Intel AMD Description: The NH-L12Sx77 is a slightly taller variant of the award-winning NH-L12S, offering improved cooling performance as well as enhanced motherboard and RAM compatibility. With six instead of four heatpipes, it provides additional thermal headroom while maintaining the same default fan setup with the fan installed below the fin stack blowing upwards. This design guarantees optimal acoustics in situations with perforated case panels right above the cooler and helps to exhaust hot air from the case. Due to the increased height, clearance for tall motherboard heatsinks or RAM modules is significantly improved, yet at a height of 77mm, the NH-L12Sx77 is still compact enough to fit popular Small Form Factor (SFF/SFX) cases. Topped off with the renowned SecuFirm2 mounting system, Noctua’s award-winning NT-H2 thermal compound, and a 6-year manufacturer’s warranty, the NH-L12Sx77 is the perfect choice for SFF builds that require strong cooling performance but cannot fit larger coolers. Features:

• Performance-enhanced taller version of the award-winning NH-L12S: Six heatpipes for improved thermal headroom, increased clearance for better motherboard and RAM compatibility
• 77mm total height and bottom-to-top airflow direction for optimal acoustics and direct exhaust of hot air in compact cases, ideal for the Fractal Design Terra, Silverstone Milo ML12 or Louqe Raw S1 chassis
• Highly optimised NF-A12x15 slim 120mm fan with Low-Noise Adaptor and PWM for automatic speed control: full cooling performance under load, near-silent at idle
• Includes high-end NT-H2 thermal paste and SecuFirm2 mounting system for easy installation on Intel LGA1851, LGA1700, LGA1200, LGA115x and AMD AM5 & AM4 (offset mounting option for best efficiency)
• Perfect for powerful yet compact and quiet Small Form Factor builds and ITX systems, deluxe choice for Intel Core & Core Ultra (e.g. 285K, 265K, 245K) and AMD Ryzen (e.g. 9950X, 9900X, 9700X, 9600X)
