With its single NF-B9 PWM 92 mm fan, the new Ghost S1 edition is tailored for use in this case and has been updated with the latest SecuFirm2 mounting hardware for all current mainstream sockets, including Intel LGA1200, LGA115x and AMD AM4. Topped off with Noctua's further improved, second-generation NT-H2 thermal compound and a full 6-year manufacturer's warranty, the NH-L12 Ghost S1 edition is the ideal choice for premium-grade quiet builds in the Louqe Ghost S1 chassis.
