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, which not only guarantees optimal acoustics in situations with perforated case panels right above the cooler, but also helps to exhaust hot air from the case. Due to the increased height, clearance for tall motherboard heatsinks or RAM modules could be improved significantly, yet at a height of 77mm, the NH-L12Sx77 is still compact enough to fit popular Small Form Factor (SFF/SFX) cases such as the Fractal Design Terra, Silverstone Milo ML12 or Louqe Raw S1. 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 the larger NH-C14S or NH-D9L.
