Who it fits
Good fit for
You should buy this if you own a Noctua NH-D15 or NH-D15S cooler and want a uniform black aesthetic. It is ideal for builds that use Noctua’s chromax line of fans and anti-vibration pads. The covers provide a clean, stealth look without altering airflow. If you value visual consistency in your case and already have the compatible cooler, this is a straightforward upgrade. It is also suitable for users who prefer a monochromatic theme over the standard brown and gray Noctua colors.
Who should skip it
Skip this product if your cooler is not a Noctua NH-D15 or NH-D15S. The covers are not universal and will not fit other brands or models. Do not buy this if you are looking for improved cooling performance. These are cosmetic shells that do not affect thermal output. You should also avoid this if you prefer the original Noctua color scheme. Since it is an add-on, you must already own the compatible cooler. It is not a standalone cooling solution for a bare CPU.
Verdict: The Noctua NA-HC4 is a specialized aesthetic accessory for specific dual-tower coolers. It delivers a consistent black look but offers no thermal benefits.
Key specs explained
Material: powder-coated aluminium
The covers use powder-coated aluminum for their construction. This material choice provides a durable surface that resists scratches and wear during handling. You get a consistent black finish that matches Noctua’s chromax aesthetic line. Unlike plastic shells, metal covers add a premium feel to your build. This spec ensures the covers maintain their appearance over time without fading or chipping.
Color: Black
The product is finished in a solid black color. This allows you to hide the silver fins of your dual-tower cooler for a stealthy look. It pairs well with black fans or case interiors. If you prefer a monochrome setup, this spec helps unify your hardware. The black finish is applied evenly to both covers included in the set.
Width: 2.56 inches
Each cover has a width of 2.56 inches. This dimension ensures it fits snugly over the side of the heatsink fins. You do not need to worry about gaps or loose fits. The width is tailored to standard dual-tower cooler dimensions. Check your cooler’s fin stack size to confirm compatibility. This precise measurement prevents interference with nearby components.
Height: 8.46 inches
The covers stand 8.46 inches tall. This height covers the majority of the fin stack on compatible models like the NH-D15. It provides a complete visual transformation rather than a partial one. Ensure your case clearance allows for this height before installation. The tall design ensures no silver fins remain visible from the side.
Weight: 12.3 ounces
The set weighs 12.3 ounces total. This weight indicates a solid build that feels substantial in your hands. It is light enough to handle easily but heavy enough to stay in place. The weight comes from the aluminum material used. You do not need additional support brackets. The mass helps the covers feel secure once installed.
Design and build overview
According to the listing, the NA-HC4 covers are crafted from powder-coated aluminum. This material choice offers a durable surface that resists scratches and wear during handling. You get a consistent black finish that aligns with Noctua’s chromax aesthetic line. Unlike plastic shells, metal covers provide a solid feel. The set includes two pieces to outfit both fin-stacks on compatible dual-tower heatsinks.
The dimensions measure 9.65 inches in length, 8.46 inches in height, and 2.56 inches in width. These specific measurements ensure the covers fit snugly over the NH-D15, NH-D15S, and NH-D15S SE-AM4 models. The weight is listed at 12.3 ounces for the pair. This mass adds negligible load to your cooler while providing structural integrity. The layout is designed for easy installation, requiring no special tools.
The finish is a matte black that matches Noctua’s chromax line fans and anti-vibration pads. This allows you to create a uniform stealth look for your build. The covers do not include any electronic components or controls. They serve purely as aesthetic add-ons. You should verify that your specific cooler model is listed as compatible before purchasing. The design focuses on visual integration rather than thermal performance changes. This makes them suitable for users who prioritize a cohesive color scheme in their system.
Setup and everyday use guide
Installing the Noctua NA-HC4 chromax.Black covers is a straightforward process. The listing highlights easy installation as a key feature. You do not need complex tools or technical expertise to proceed. The set includes two covers, which allows you to outfit both fin-stacks on compatible dual-tower heatsinks. This ensures a symmetrical and uniform appearance across your CPU cooler.
Compatibility is specific. These covers are designed exclusively for Noctua NH-D15, NH-D15S, and NH-D15S SE-AM4 dual-tower heatsinks. You must verify that your cooler model matches one of these before purchasing. The covers measure 9.65 inches in length, 8.46 inches in height, and 2.56 inches in width. They weigh 12.3 ounces. These dimensions ensure a snug fit over the existing aluminum fins without obstructing airflow or requiring modification to your cooling setup.
In daily use, the powder-coated aluminum construction provides a durable surface. It resists scratches and wear during routine handling. The black finish offers a sleek, stealth look that integrates well with Noctua’s chromax line of fans and anti-vibration pads.

Before you buy
You must verify that your cooler is a Noctua NH-D15, NH-D15S, or NH-D15S SE-AM4. The covers fit only these specific dual-tower models. You need both covers to outfit the entire heatsink, as the set includes two units. Check that your fan setup aligns with the chromax aesthetic. The listing suggests pairing these with Noctua chromax line fans and anti-vibration pads for a cohesive look. Upkeep is minimal. The powder-coated aluminum surface resists scratches, but you should handle the covers gently to avoid denting the thin metal. Dust accumulation is similar to the cooler fins themselves. You can wipe them with a dry cloth. This accessory does not improve cooling performance. It is purely cosmetic. If you already have a black-themed build, these covers help unify the visual appearance. If your cooler is not compatible, these will not fit. You cannot use them on single-tower or third-party coolers. Ensure your case has enough clearance for the full dual-tower height before adding these covers.
Check before you buy
- Verify your cooler is an NH-D15, NH-D15S, or SE-AM4 model.
- Confirm you need two covers for both fin-stacks.
- Check if your fans match the chromax black aesthetic.
- Ensure case clearance allows for the full dual-tower height.
