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 95x95mm footprint, the NH-D9L does not overhang the RAM slots on current Intel and most AMD mainboards. This gives the user full access to the memory modules and guarantees 100% compatibility with tall heatspreaders or optional memory fans. Please note however that some AMD mainboards violate the 96x114mm keep-out zone specified by AMD, so the NH-D9L can only be used with RAM modules of up to 30mm height on these boards. Please consult our compatibility list for details.

100% compatibility with PCIe cards on mini-ITX
Many Intel LGA17xx/1200 based mini-ITX motherboards have the PCIe slot sitting right next to the 95x95mm socket zone. While larger coolers that exceed this zone are likely to block the PCIe slot, the 95x95xmm sized NH-D9L provides full compatibility with PCIe cards, be it on ATX, microATX or ITX.
