The NA-HC3 chromax.black.swap 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 and including swappable inlays in black, white, red, blue, green and yellow, they allow users to colour-customise the cooler in order to coordinate it with popular build colour schemes such as all black, black and white or black and red. 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-HC3 chromax.black.swap covers give you endless possibilities to design your very own, individual NH-D15(S) that looks just as great as it cools! Caution: The covers increase the height of the heatsink by 5mm (from 160 to 165mm) and the width by 3mm (from 150mm to 153mm). Please make sure that your case offers sufficient clearance and that the covers don't make contact with any other components such as PCIe cards! chromax.black.swap design with swappable colour inlays The NA-HC1 chromax.black.swap comes with swappable inlays in black, white, red, blue, green and yellow that allow colour-coordinating the heatsink with most popular build colour schemes. Whether you're designing your dream machine for the years to come or switch parts on a monthly basis, matching colours has never been so easy! Create your own inlays in custom colours Do you want to use a custom colour for your new project? Creating custom-coloured inlays for the chromax.black.swap covers couldn't be easier: Either spray-coat one of the supplied ones or cut a 150x36mm piece of paper, cardboard or plastic (max. thickness 0.5mm), put it inside the cover and you're ready to go!
