The NA-HC4 chromax.white cooler cover set is an accessory for Noctua's award-winning NH-D15, NH-D15S and NH-D15 SE-AM4 CPU coolers. The covers, made of high-quality black powder-coated aluminium, give the cooler an elegant snow-white look that perfectly matches systems designed entirely in white or in black and white. Thanks to the foolproof assembly, it takes only a few minutes to change the appearance of an NH-D15(S), without even having to remove the cooler from the CPU. Caution: The covers increase the overall height of the cooler by 5 mm (from 160 to 165 mm) and the width by 3 mm (from 150 to 153 mm). Please make sure that your case has sufficient space and that the covers do not come into contact with other components such as PCIe cards.
