Noctua NH-L12 L-Type Low-Profile Cooler Review @ OCIA.net
 

Often built into micro-ATX or smaller chassis, HTPC aficionados demand small size and silent operation over sheer performance. Noctua aims to target the HTPC crowd with the release of their latest cooler, the NH-L12. Following in the footsteps of their C-Type NH-C14 that we reviewed here last year, the L12 offers a similar top-flow design in a slimmer, lower profile, while retaining a dual-fan configuration and incorporating their latest F-Series Focused-Flow PWM fan.
