Black vs White Heatsink Cover Specs
color options
The Noctua NA-HC3 chromax.Black.swap offers swappable inlays in six colors: red, blue, green, yellow, black, and white. This allows you to change the look over time. The Noctua NA-HC4 chromax.White provides a fixed sleek, snow-white finish. If you want a permanent white aesthetic, the NA-HC4 is the direct choice. If you prefer flexibility to match changing build themes, the NA-HC3 is superior. The swappable feature adds versatility that the fixed white cover cannot match.
compatible device
Both covers are designed for Noctua dual-tower coolers. The NA-HC3 fits the NH-D15, NH-D15S, and NH-D15S SE-AM4. The NA-HC4 also lists compatibility with the NH-D15, NH-D15S, and NH-D15S SE-AM4. Both sets include two covers for outfitting both fin-stacks. There is no difference in which CPU coolers they support. You can use either cover on the same dual-tower heatsinks without issue. The compatibility is identical for both products.
material quality
Both the NA-HC3 and NA-HC4 are made from high-quality powder-coated aluminum. This material choice ensures durability and a consistent finish. The powder coating protects the aluminum while providing the desired black or white color. Since both use the exact same material construction, there is no difference in build quality or material specs. You get the same tactile feel and protective layer regardless of which color you choose.
dimensions
The NA-HC3 measures 6.5 inches in width, 21.5 inches in height, and 24.5 inches in length. The NA-HC4 measures 9.65 inches in width, 2.56 inches in height, and 8.46 inches in length. These dimensions are significantly different, likely reflecting the cover design or measurement points for the fin stacks. The NA-HC3 appears taller and longer, while the NA-HC4 is wider but much shorter. You should verify these measurements fit your specific cooler layout before buying.
weight
The NA-HC3 weighs 12.3 ounces. The NA-HC4 weighs 13.4 ounces. The difference is 1.1 ounces. This is a minor variation that will not affect installation or cooler performance. Both covers are light enough to be handled easily during installation. The weight difference is negligible for practical purposes. You do not need to worry about the slight mass difference when mounting the covers on your dual-tower heatsink.
