SVALT Cooling Dock model DHCx with vertical section diagram Based on New 3rd Generation DHC Design
The DHCx is based on the new 3rd gen DHC design’s deeper and angled cooling fin air channels, thinner laptop coupling plate, thinner laptop thermally conductive materials, and front horizontal channel with curving ends. The DHC model was designed for silent passive airflow or optional active airflow with the use of a separate Fx Cooling Fan accessory, while the new DHCx model has been designed with a built-in cooling fan to provide a more compact and conveniently single item configuration.

SVALT Cooling Dock model DHC anodized aluminum gray, black and silver colors Aluminum Color and Finish
The DHCx’s aluminum heatsink is available in gray, black and silver anodize colors (as shown in the above photo). There are different strategies for color selection, such as selecting the color that matches a laptop or selecting a color for improved heat transfer. If you want to select a matching color then the gray is similar to Apple’s Space Gray, the black is similar to Apple’s Midnight, and the silver is similar to Apple’s Silver. If you want higher heatsink performance, then a darker color will offer a slight improvement, such as gray compared to silver, and black offering the best. Each selection strategy is valid and depends on the customer’s priorities.

All colors are finished by hand with a heavy DA-sanding and heavy bead-blasting to produce a more even and consistent surface with a deeply textured matte finish optimized for increased surface area, improved heat transfer to passive/active airflows, and improved radiant heat transfer.

Aluminum docks are anodized in weekly batches by model and color, so the listed “est. build lead time” can fluctuate and might differ between colors based on the anodize schedule and based on estimated order build lead time.

SVALT Cooling Dock model DHCx modular diagram Built-in Fan Cooling System
The DHCx is available with a three fan kit for customers to select the best fan for their setup. The B16 can be used for baseline always-on ultra-quiet cooling. The W20 offers more aggressive hi-airflow cooling that can be used in less noise sensitive environments or switched on/off as needed. The R17 is pre-installed for a good balance between audio and cooling performance.

The DHCx is also available with a black B22 variable speed fan that 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.

The two above fan configurations include 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.

Future Configurations
The cooling system’s bolt and snap modular system allows for easy and quick fan exchange through accessories, and the cooling system will work with most any standard 80x80x25mm fan (see specs). We also offer a variety of upgrade options to our customers.
