Noctua is introducing the NH-L12Sx77 today, a variant of its original low-profile CPU cooler for Small Form Factor systems that features some changes for improved cooling, including six heat pipes—two more than the NH-L12S—enabling more headroom for higher heat-loads generated by today’s high-end CPUs. This version of the cooler also features a taller, 77-mm height, enabling enhanced compatibility with memory and other taller motherboard components.

Noctua on its new cooler:
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.
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.
Like the regular NH-L12S, the NH-L12Sx77 has its fan preinstalled 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.
At a height of 77mm (7mm taller than the original NH-L12S’ 70mm), the NH-L12Sx77 is a perfect fit for Fractal Design’s Terra (with the maximum space setting for the CPU cooler), SilverStone’s Milo ML12 or Louqe’s unique, award-winning RAW S1 chassis as well as many other cases that cannot fit the larger NH-C14S (115mm in low-profile mode) or NH-D9L (110mm).
