Despite the compact design, measuring just 111mm tall! The D9L features a dual tower design, yet still provides perfect clearance for RAM modules, as well as keeping clear of any PCIe expansion cards. It's small enough to fit in a mini-ITX system build, but for the more professional hardware enthusiast, it'll be perfect for 3U systems too. Noctua build quality is world-famous, and to support their confidence, the D9L comes with a whopping six-year warranty! That's confidence in their products right there.

?The included NF-A9 premium fan supports automatic speed control via PWM for outstanding quietness of operation and a second, optional NF-A9 fan can be added for further improved performance in dual fan mode. Topped off with the trusted, pro-grade SecuFirm2? multi-socket mounting system, Noctua's proven NT-H1 thermal compound and full 6 years manufacturer's warranty, the NH-D9L forms a highly compact premium package for space-restricted applications.?
