Quiet Active Airflow and Conductive Heatsink Cooling for Closed-Screen Laptops


The innovative first-of-kind DHCx Cooling Dock is specially designed, engineered and sculpted from solid aluminum to support and quietly cool current and prior generation Apple laptops.

The DHCx’s heatsink is carved from solid 6061 aluminum to create five cooling fins with four air channels cut to an incredible two inch depth, which provides the heatsink with a large surface area for improved heat transfer. The DHCx’s heatsink is made from continuous material with deep cooling fins to improve heat transfer, as well as improving heat flow within the heatsink mass. Compared to typical low-cost bolted or cast heatsinks, creating the DHCx’s heatsink requires higher precision, longer CNC milling times and higher costs.

The machined heatsink is then painstakingly finished by hand with sanding, bead-blasting and anodize to create a non-glossy matte finish with extra course texture for increased surface area, greater heat transfer and improved heatsink cooling efficiency. The heatsink’s laptop coupling plate has a specially prepared finish to produce a flat surface for improved heat transfer through a thermally conductive interface that couples with the laptop to efficiently extract heat while protecting the laptop’s finish. Edge pads wrap around all four sides of the heatsink’s coupling plate to protect the laptop from impact without heat transfer interference. The coupling system and padding is installed by hand onto the heatsink, and is made from the highest-quality and best performing materials to simultaneously transfer heat and protect the laptop. The heatsink can also be configured without the thermally conductive material overlay for direct metal-to-metal coupling between the laptop and heatsink.

The DHCx not only achieves high levels of heatsink cooling efficiency, but has a design tailor made for optimal performance with the latest generation of Apple laptops, such as the 2021-2023 MacBook Pro. The DHCx’s heatsink is positioned at the laptop processor location to extract heat at the heat source. The overall support cradle width, heatsink coupling plate width and air channel locations match the laptop’s processor and built-in cooling system layout. The heatsink’s extra large central through-hole connects to a horizontal air channel with curving ends to supply cool air to the laptop’s center intake vent and flush out hot exhaust air for more efficient operation of the laptop’s built-in cooling system. The extra large through hole creates an open air space below the five vertical air channels to generate a passive current of cool air that continuously rises up to cool the six vertical cooling fins.

The DHCx’s air channels support silent passive cooling airflow, while a built-in cooling fan boosts heatsink cooling performance. The vertical air channels send cooling airflow upward to cool the laptop enclosure, and the internal angle guides cooling airflow down through the central through hole and front horizontal channel to flush out hot air and internally cool processors on laptops with a center intake vent, such as the 2021-2023 MacBook Pros (M2/M1 Pro/Max), 2012-2015 MacBook Pros (Intel Retina) and 2010-2017 MacBook Airs (Intel non-Retina).

The DHCx and all Cooling Dock models feature a unique and stable leaning configuration for easy closed-screen clamshell setup while the laptop remains connected to cables and safely in a padded cradle with adjustable / replaceable laptop support pads. All SVALT products are made with enduring metal construction milled from solid aluminum in the Pacific Northwest. All SVALT cooling systems use modular bolted / snapped cooling system assemblies and ship with the tools required for right-to-repair servicing, exchanging and upgrading.


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 DHCx thermal coupling options diagram Laptop Coupling Interface
The DHCx is available with two different configurations for the laptop’s thermally conductive coupling interface. The “thin overlay” configuration is recommended for most customers as it offers lower impedance and improves heat transfer while protecting the laptop finish. The “bare metal” configuration is offered for customers that want metal-to-metal contact between laptop and heatsink for direct heat transfer. The “bare metal” configuration includes the edge bumper pads to provide edge impact protection but the laptop will directly contact the heatsink’s anodized aluminum coupling plate that extends slightly beyond the pads to achieve proper surface-to-surface contact, and as a result, customers that select the “bare metal” configuration need to take care when placing the laptop on the dock (customers assume full responsibility for the care and condition of their device).

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 darker color for improved heat transfer. Each selection strategy is valid and depends on the customer’s priorities. For customers that prioritize performance and select the "bare metal" configuration, then selecting black is recommended to further improve performance.

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. The heatsink's coupling plate differs from the rest of the heatsink to produce a flatter and smoother surface finish optimized for improved conductive heat transfer from the laptop. For customers that select the “bare metal” configuration, then the coupling plate surface prioritizes functional performance and may not have a finish that is as cosmetically even as the rest of the heatsink.

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 B16 is recommended for baseline always-on ultra-quiet cooling. The W20 is recommended for more aggressive cooling that can be used in less noise sensitive environments or switched on/off as needed. The R17 falls between the B16 and W20, and is recommended as a good balance between audio and cooling performance. All three B16, R17 and W20 fans can be order bundled together with the R17 pre-installed and the B16 and W20 ready to quickly and easily exchange. The B22 option includes a Noctua NF-A8 PWM fan, Noctua NA-FC1 PWM dial viable-speed controller, and Noctua accessories. All of the 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. There also a DIY option that is the Cooling Dock without the fan cooling system or associated fan accessories so that the user can setup a cooling system as they prefer. See the Specifications section below for additional details.

Future Options
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.

Cool by Design

When it comes to using your laptop, heat generation and increased performance are in a cyclical relationship that feed off of one another. Processors generate heat that can spin up internal fans, stress systems, degrade hardware and throttle processors. This is the basic problem all laptop users face, the more you want to do with your laptop, the harder it works, and the hotter and slower it gets.

  • Conductive Cooling

    The DHCx uses an innovative thermally conductive interface to transfer heat from laptop processors to heatsink for a substantial increase in cooling performance.The thermally conductive interface uses edge bumper pads along all four sides to protect the laptop during setup. A user installed pad locks the laptop in place for improved thermal coupling (extra pads included for future setups).

  • Heatsink Cooling

    Sculpted from solid aluminum, the DHCx’s thermally massive heatsink transfers heat from the laptop to fan driven cooling airflow through extra wide vertical air channels and cooling fins. The DHCx’s integrated fan flushes out hot air, accelerates heat transfer, cools laptop enclosure, and internally cools processors on compatible laptops, such as the 2021-2023 MacBook Pro.

Setup for Cool

Running a laptop with the screen closed in clamshell mode offers compelling benefits, such as a more compact and ergonomic workstation, reduced wear on built-in components and improved external display performance, however, clamshell mode also traps heat, resulting in a greater need for supplemental cooling.

  • Current Laptop Optimization

    The DHCx’s dimensions, air channels and cooling features have been designed to work seamlessly with the built-in cooling systems of Apple’s current and prior generation laptops, allowing hot air to escape through laptop exhaust vents and cool air to reach laptop intake vents. The integrated cooling fan drives cool air directly onto processors in compatible laptops, such as the 2021-2023 MacBook Pro (16-in shown above).

  • Innovative Clamshell Setup

    The DHCx has been optimized to support and cool Apple laptops, while a leaning support works with a wide variety of PC laptops. The unique leaning support provides an easy clamshell setup by holding the laptop safely within the padded cradle while opening the lid to access the power button with cables connected. The heavy mass and non-slip padded cradle provide a stable non-tip support for larger and heavier laptops, such as the 16-inch MacBook Pro (shown above).

Objects of Substance

SVALT is a mission driven company that offers something different with products that are as much art as tech, and as much objects of substance as machines engineered for performance. Made locally with care in the Pacific Northwest, SVALT products endure with solid metal construction, right-to-repair maintenance, easy upgrades, and a focus on sustainability.
