Successor to the award-winning NH-L12, the NH-L12S is a compact low-profile CPU cooler that combines excellent compatibility, surprising efficiency & remarkable flexibility. Thanks to its NF-A12x 15 PWM a slim 120mm fan, the NH-L12S provides even better quiet cooling performance than the previous model with its 92mm fan. At the same time, the NH-L12S is highly versatile: with the fan installed on top of the fins, the cooler is compatible with RAM modules of up to 48mm in height. With the fan installed underneath the fins, the total height of the cooler is only 70mm, making it suitable for use in many HTPC & Small Form Factor cases. Topped off with the trusted, pro-grade Secu Firm 2 multi-socket mounting system, Noctua’s proven NT-H1 thermal compound & a full 6-year manufacturer’s warranty, the NH-L12S is a premium-quality low-profile solution for the highest demands. Based on the award-winning NH-L12 Having received more than 200 awards & recommendations from leading international hardware websites & magazines, the NH-L12 has become an established reference for low-profile 120mm top-flow coolers. Equipped with the new NF-A12x 15 fan, the new S-version provides more flexibility & enhanced performance in low-profile mode. Low-profile mode Run with the NF-A12x 15 fan installed underneath the fin stack, the NH-L12S stands only 70mm tall. The fan can be installed blowing upwards or blowing downwards in order to match the airflow direction inside the case. High-clearance mode Run with the NF-A12x 15 fan installed on top, the NH-L12S provides extended clearance underneath the fin stack. This way, it is fully compatible with chipset coolers & RAM modules with heat-spreaders of up to 48mm in height (vs. 35mm in low-profile mode). NF-A12x 15 slim 120mm premium fan Featuring sophisticated aerodynamic optimisations such as Flow Acceleration Channels, the NF-A12x 15 is a premium-grade slim 120mm fan. Its outstanding efficiency allows the NH-L12S to provide even better performance than the previous model with its 92mm fan. PWM support & Low-Noise Adaptor The NF-A12x 15 premium fan supplied with the NH-L12S supports PWM for convenient automatic speed control through the motherboard. In addition, the maximum fan speed can be reduced from 1850 to 1400rpm using the supplied Low-Noise Adaptor for even quieter operation. 120x 25mm fan support The fan clips supplied with the NH-L12S work not only with the slim NF-A12x 15 fan but also with 25mm thick 120mm fans. Users who have extra room inside their cases can thus boost the cooler’s performance by using a standard 120x 25mm fan on top (increases total height to 95mm).
