Description

The Noctua NH-L12S is the successor to the award-winning NH-L12, offering a compact low-profile CPU cooler designed for excellent compatibility, efficiency, and flexibility. Equipped with the slim NF-A12x15 120mm PWM fan, it delivers quieter and more efficient cooling than its predecessor’s 92mm fan. The cooler supports flexible fan placement: on top of the fins to accommodate RAM modules up to 48mm tall or underneath the fins for an ultra-low total height of just 70mm, making it ideal for HTPC and small form factor PC cases. It features Noctua’s trusted SecuFirm2 multi-socket mounting system and comes with premium NT-H1 thermal compound. With a full 6-year manufacturer warranty, the NH-L12S is perfect for users seeking a premium-quality, low-profile cooling solution for CPUs with moderate heat output.
