The NH-D9L chromax.black is an all-black version of Noctua’s award-winning NH-D9L compact dual-tower CPU cooler that has been designed to provide excellent quiet cooling performance at a height of only 110mm. Its comparably low profile (15mm lower than classic 9cm tower coolers such as the NH-U9S) doesn’t only guarantee full 3U compliance but also makes the NH-D9L ideal for compact mini-ITX and Small Form Factor cases that have airflow paths parallel to the motherboard. Thanks to its 95x95mm footprint, the NH-D9L always clears the RAM and PCIe slots, even on ITX motherboards.
