Low-profile tower design for better airflow efficiency
While most low-profile coolers blow air towards the motherboard, the NH-D9L is a tower style cooler that bows parallel to the mainboard, which allows for superior airflow efficiency in cases with front intake and rear exhaust fans that create an airflow path parallel to the mainboard.

100% RAM compatibility
With its compact 95x95mm footprint, the NH-D9L does not overhang the RAM slots on Intel LGA1851 / LGA1700 / LGA1200 / LGA115x and AMD AM5 / AM4 based motherboards no matter in which orientation it is installed. This ensures easy access to the modules and 100% compatibility with DIMMs that feature tall heat-spreaders or RGB lighting.

100% compatibility with PCIe cards
Many mini-ITX motherboards have the PCIe slot sitting close to the socket zone. While larger coolers that exceed this zone are likely to block the PCIe slot, the 95x95mm sized NH-D9L provides full compatibility with PCIe cards, be it on ATX, microATX or ITX.
