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.

Performance-enhanced low-profile cooling

With 6 instead of 4 heatpipes, the NH-L12Sx77 offers significantly more headroom for higher heat-loads compared to the original NH-L12S. As such, it is ideal for getting the most out of today’s high-end CPUs in compact cases where their aggressive turbo boost modes are especially challenging to handle.

Better performance, better compatibility

The NH-L12Sx77 not only improves performance but also motherboard and RAM compatibility versus the original NH-L12S: Due to the x77 version’s taller construction, clearance for RAM modules as well as motherboard heatsinks and shrouds could be increased significantly, which makes the cooler an easy fit in most configurations.

Exhaust airflow direction

The NH-L12Sx77 has its fan pre-installed underneath the fin stack blowing upwards, which is ideal in compact cases that typically have a perforated panel right above the cooler as hot air can be exhausted directly instead of accumulating inside the case. At the same time, this setup avoids noises from influx turbulences that occur when fans are drawing in air through perforated panels.
