DHC CONFIGURATIONS

3rd Generation Design
The DHC is available with a new 3rd generation design that has been significantly updated with the following revisions for improved cooling performance, especially with long-duration and high-intensity workloads:

• Up to 96% deeper cooling fin air channels and thinner thermally conductive coupling plate for increased cooling surface area and improved heatsink cooling.
• 23% thinner thermally conductive material assembly for reduced impedance and improved heat transfer from the laptop to heatsink.
• Angled vertical cooling air channels for improved internal processor cooling when used with the optional Fx Cooling Fan and laptops that include a center intake vent, such as the 2021-2023 MacBook Pros, 2012-2015 MacBook Pros (Intel Retina) and 2010-2017 MacBook Airs (Intel non-Retina)

2nd Generation Design
Both the 3rd and 2nd generations include curving cutouts in the front horizontal air channel for improved airflow and heatsink cooling.


Heatsink Colors and Coupling Plate
The heatsink uses a special finish to improve heatsink cooling performance. The body of the heatsink is finished by hand with sanding, heavy bead-blasting and a short anodize to produce a deeply-textured micro-porous non-glossy matte finish that increases the active area of the heatsink for higher radiant emissivity cooling and improved conductive cooling from both passive and active airflows. The aluminum heatsink is available with the following anodize colors as shown in the above image and listed below from left to right:

• Silver: The silver color is similar to Apple’s Silver.
• Gray: The gray color is similar to Apple’s Space Gray.
• Dark Gray: The dark gray color is similar to Apple’s Space Black.
• Black: The black color is a full and deep black.

Heatsink Coupling
The aluminum finish of the laptop coupling plate is specially prepared with a fine hand sanded finish and protected from the heavy bead-blasting used on the rest of the heatsink to produce an extra-flat and extra-smooth surface finish for improved laptop coupling and higher conductive heat transfer.

A special assembly of ultra-thin low-impedance thermally conductive materials cover the aluminum laptop coupling plate. The assembly uses an ultra-thin material to improve heat transfer, however, the semi-transparent assembly may show surface variations such as areas of lighter, darker or uneven coloring. The underlying anodize color will show through semi-transparent assembly, so the anodize color will impact both the resultant color of the assembly and visibility of surface variations. For instance, the lightest anodize color (silver) will result in the lightest yellow assembly color with the least visible surface variations, while the darkest anodize color (black) will result in the darkest orange assembly color with the most visible surface variations.

See Specs under product details for additional details.


Fx Cooling Fan Accessory
The DHC has been designed to work with the optional Fx Cooling Fan accessory that boosts heatsink cooling, as well as providing direct internal processor cooling on 2021-2023 MacBook Pros, 2012-2015 MacBook Pros (Intel Retina) and 2010-2017 MacBook Airs (Intel non-Retina). The separate Fx Cooling Fan design moves more air with less noise, while also allowing the heatsink to be as large as possible with the most thermal mass and cooling surface area.

The Fx is sold below our cost to offer customers a quiet compact desk fan made from high-quality materials with full right-to-repair modularity. The Fx includes an additional $10 discount when bundled with the DHC, or the Fx can be purchased separately in the future. The Fx is available with the following fan configurations:

• FxR17 w/ B16 and W20: The Fx ships with the R17 fan installed, and includes the B16 and W20 fans for users to exchange to best meet their workstation cooling and noise preferences. The black B16 fan can be used for baseline always-on ultra-quiet cooling. The white W20 fan offers more aggressive hi-airflow cooling that can be used in less noise sensitive environments or switched on/off as needed. The red R17 fan is pre-installed for a good balance between audio and cooling performance.
• FxB22: The Fx ships with the B22 fan installed. The black B22 variable speed fan covers the full range of ultra-quiet to hi-airflow cooling performance. The B22 is a high-end Noctua NF-A8 PWM chromax.black.swap fan that is controlled with Noctua’s NA-FC1 PWM dial-variable speed controller.

All of the fan configurations include front and back black anodized fan supports, front and back black metal fan screen, mounting fasteners, fan 2/3/4-pin fan adapter with on/off switch, 12 volt power supply (fixed for North America and multi-plug for other locations) and hex key for right-to-repair disassembly. See the Fx Cooling Fan product page for additional details.


Fan Colors
