The NH-D9L is a premium dual-fin battery cooler designed to deliver a high level of cooling despite a height of only 110mm. Its exceptionally small footprint (15mm smaller than conventional 9cm models such as the NH-U9S) not only ensures full 3U compatibility, but also allows the model to fit seamlessly into compact HTPCs and small form factor enclosures where airflow flows parallel to the motherboard. With a 95x95mm footprint, the NH-DL9 does not encroach on memory slots or PCIe ports on all Intel ITX motherboards and most AMD models. The included PWM-compatible NF-A9 fan allows automatic rotation speed control and therefore surprisingly quiet operation. An optional second NF-A9 can also be installed in Dual Mode to meet an increased need for performance if necessary. Complemented by the SecuFirm2™ multi-socket mounting system, a true top-of-the-line benchmark in the field, and the famous NT-H1 thermal paste but also backed by a 6-year manufacturer's warranty, the NH-D9L is a very compact premium solution ideal for tight environments.
