"Standing at only 37mm tall with fan, the NH-L9a-AM4 L-Type low-profile cooler easily fits any slim case and its small footprint easily accommodates RAM and PCIe components, especially on AMD based mini-ITX motherboards with their near socket connectors. The NH-L12S L-Type low-profile cooler offers a slightly larger fin dissipation area, four heat-pipes, and with the new NF-A12x15 PWM fan you get better thermal performance potential."
