The cooler cover NA-HC2 chromax.black is an accessory for Noctua's award-winning CPU coolers NH-U12S, NH-U12S TR4-SP3, NH-U12S SE-AM4 and NH-U12S DX-3647. The cover, made of high-quality black powder-coated aluminium, gives the cooler a sleek stealth look that perfectly matches completely black systems as well as many other popular colour schemes. Thanks to the foolproof assembly, it takes only a few minutes to change the appearance of an NH-U12S, without even having to remove the cooler from the CPU. Caution: The cover increases the overall height of the cooler by 6 mm (from 158 to 164 mm) and the width by 3 mm (from 125 to 128 mm). Please make sure that your case has sufficient space and that the cover does not come into contact with other components such as PCIe cards.
