The NA-HC4 chromax.black heatsink covers are an add-on accessory for Noctua’s award-winning NH-D15, NH-D15S and NH-D15 SE-AM4 CPU coolers. Made from high-quality aluminium with black powder-coating finish, they allow users to give the cooler a sleek stealth look that is right at home in all-black builds and goes nicely with many other popular colour schemes. Thanks to the easy, straightforward installation, changing the looks of your NH-D15(S) cooler only takes a few minutes and doesn’t even require taking it off the CPU. Combined with chromax.black.swap edition NF-A15, fans, the two NA-HC4 chromax.black covers give you the option to turn your NH-D15(S) into an all-black powerhouse that looks just as great as it cools.
