Noctua NH-U9S is a premium quality quiet CPU cooler in classic 9cm size. Its asymmetrical design with 5 heat pipes not only provides even better cooling performance than the previous generation but also improves compatibility. Thanks to its 95x95mm footprint, the NH-U9S clears the RAM and PCIe slots on all Intel and most AMD based mainboards, including µATX and ITX.

The NH-L9a-AM4 is the latest, AM4-specific revision of Noctua's award-winning NH-L9a low-profile CPU cooler for AMD Ryzen-based HTPCs and Small Form Factor (SFF) systems. At a height of only 37mm, the NH-L9a is ideal for extremely slim cases and, due to its small footprint, it provides 100% RAM and PCIe compatibility as well as easy access to near-socket connectors even on tightly packed mini-ITX motherboards.
