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.

High clearance mode
Run with the NF-A12x15 fan installed on top, the NH-L12Sx77 provides extended clearance underneath the fin stack. This way, it is fully compatible with chipset coolers and RAM modules with up to 56mm in height (compared to 44mm in the default configuration with the fan installed underneath the fin stack).

NF-A12x15 slim 120mm premium fan
Featuring sophisticated aerodynamic optimisations such as Flow Acceleration Channels, the NF-A12x15 is a premium-grade slim 120mm fan. Its outstanding efficiency enables the NH-L12Sx77 to combine excellent cooling performance with superb quietness of operation.

NT-H2 next-gen thermal compound
For high-end builds in compact cases, every degree counts. This is why the NH-L12Sx77 includes a tube of Noctua’s next-generation NT-H2 compound that provides even better performance than the award-winning NT-H1, allowing you to achieve the best possible cooling results.
