Noctua NA-HC4 Black vs White
Color finish
The primary difference between these two Noctua models is the visual finish. The NA-HC4 chromax.Black provides a sleek, black stealth look for your cooling hardware. In contrast, the NA-HC4 chromax.White offers a matching snow-white appearance. Both units use the same high-quality powder-coated aluminum material. This ensures the finish is durable and consistent across both color options. You choose the Black version for a dark theme or the White version for a light aesthetic. The material quality remains identical, so the choice depends entirely on your preferred color scheme.
Compatibility
Both heatsink covers are designed for the same specific CPU coolers. They fit the Noctua NH-D15, NH-D15S, and NH-D15S SE-AM4 dual tower heatsinks. Each set includes two covers to outfit both fin-stacks of the cooler. This compatibility applies equally to the Black and White editions. You do not need to worry about fitment differences between the colors. The mounting mechanism and dimensions are identical. This means you can mix and match fans or pads from the chromax line regardless of the cover color you select. The functional compatibility is exactly the same for both products.
Weight
There is a slight difference in the weight of the two covers. The Noctua NA-HC4 chromax.Black weighs 12.3 ounces. The Noctua NA-HC4 chromax.White weighs 13.4 ounces. The White version is 1.1 ounces heavier than the Black version. This difference is minimal and unlikely to affect the structural integrity of your cooler. Both weights are well within safe limits for the dual tower heatsinks they support. The variation in weight may be due to minor differences in the powder coating application or material density. For most users, this weight difference is negligible when considering the overall build of the cooling system.
Dimensions
The dimensions listed for each product appear to swap values, likely due to orientation in the data. The Black cover lists width as 2.56 inches, height as 8.46 inches, and length as 9.65 inches. The White cover lists width as 9.65 inches, height as 2.56 inches, and length as 8.46 inches. Despite this labeling difference, the physical footprint is identical. Both covers are designed to fit the same fin-stack size on the NH-D15 series. The actual physical size of the aluminum covers is the same. You can rely on the fact that they will both cover the same area on your cooler without any size conflicts.
Warranty
Both Noctua heatsink covers come with the same manufacturer warranty. Each product includes a 6-year manufacturer's warranty. This warranty coverage is identical for both the Black and White editions. You receive the same level of protection and support regardless of the color you choose. This long warranty period reflects Noctua's confidence in the durability of their powder-coated aluminum construction. It also provides peace of mind for your investment. The warranty terms do not vary between the two color options, ensuring consistent customer service and product reliability for both buyers.

Frequently asked questions
Do the black and white NA-HC4 covers change cooling performance?
No. These covers are aesthetic add-ons that do not alter thermal performance. They are made from powder-coated aluminum and fit compatible dual-tower heatsinks without affecting airflow. You can choose either color based on your build's look without worrying about temperature changes.
What are the exact dimensions of the NA-HC4 covers?
The black version measures 2.56 inches in width, 8.46 inches in height, and 9.65 inches in length. The white version has slightly different orientation specs: 9.65 inches in width, 2.56 inches in height, and 8.46 inches in length. Both fit the same dual-tower cooler models.
Which cover is heavier, the black or the white one?
The white cover weighs 13.4 ounces, while the black cover weighs 12.3 ounces. The white model is slightly heavier by one ounce. This minor weight difference does not impact installation or stability on your Noctua dual-tower cooler.
Are these covers compatible with all Noctua coolers?
No. They are designed specifically for compatible Noctua dual-tower heatsinks, such as the NH-D15 series. They are not universal accessories for single-tower or other cooler types. Check your cooler model to ensure it supports the NA-HC4 cover fitment.
What material are the NA-HC4 chromax covers made from?
Both the black and white covers are constructed from powder-coated aluminum. This material provides a durable finish that resists scratches and wear. The powder coating ensures a consistent color appearance that matches your chosen aesthetic theme.
Can I mix black and white covers on one cooler?
Technically, yes, but it is not recommended. Each cover is designed to fit both fin stacks of a dual-tower cooler. Mixing colors would create a mismatched look. For a uniform appearance, stick to either the all-black or all-white version.
