SVALT products are unique first-and-only products of their kind with innovated designs and features, as well as numerous issued and pending patents. Made locally in the Pacific Northwest with a focus on sustainability and enduring metal construction, all SVALT products use modular bolted/snapped cooling system assemblies and ship with the tools required for right-to-repair servicing, exchanging and upgrading.
SVALT Cooling Dock models work with the laptop operating in closed-screen clamshell mode and feature a unique and stable leaning configuration for easy clamshell setup while the laptop remains connected to cables and safely in a padded cradle with adjustable/replaceable laptop support pads.
SVALT Cooling Stand models use a fully modular bolt/snap system with exchangeable components and reconfigurable models. All laptop Cooling Stand models are designed to work with the laptop screen open for a more visually ergonomic workstation, either with the user typing directly on the rigid no-bounce stand or using external keyboard and display.

Silent Conductive Heatsink Cooling for Closed-Screen Laptops
The new 3rd generation DHCR offers the ultimate in silent heatsink cooling performance tailored to Apple’s latest flat backed laptops (2021-2023 MacBook Pro and 2022-2023 MacBook Air), as well as working with current and prior generation Apple laptops. The DHCR features rectilinear styling, a thin extra large thermally conductive interface to more effectively extract heat from the laptop and transfer it to a 2.6 pound heatsink carved from solid aluminum with 11 deep cooling fin air channels to create an exceptionally large 137 square inches of cooling fin surface area for improved heatsink cooling. When used with an optional Fx Cooling Fan, the heatsink’s angled air channels boost heatsink and internal processor cooling (center vent laptops 2021-2023 MacBook Pros, 2012-2015 MacBook Pros and 2010-2017 MacBook Airs). By designing the heatsink to work with a separate fan, the Fx Cooling Fan moves more air with less noise, while allowing for maximum heatsink cooling capacity. If also interested in the DHC, then see the DHCR vs DHC comparison.

Compare DHC vs DHCx

- DHC: The DHCR and DHC designs prioritize maximum heatsink performance for both silent passive airflow and fan driven active airflow. Separating the cooling fan from the heatsink avoids having to remove thermal mass and cooling surface area to make room for a built-in fan, which provides the DHCR and DHC heatsinks with higher cooling capacity. The separated fan also allows the fan to be located within unrestricted open air for increased airflow and decreased noise.

- DHC: #2 overall performance ranking with optional Fx Cooling Fan.
- DHCx: #3 overall performance ranking compared to the DHC with Fx, but out performs the DHC without the Fx.
- DHC: 6 wide cooing fins and 5 wide vertical air channels for increased cooling airflow for increased cooling surface area.
- DHCx: 5 wide cooing fins and 4 wide vertical air channels for increased cooling airflow.
- DHC: 72 square inches of cooling fin surface area for increased heat transfer to passive and active airflow.

Compare DHCx vs Dx

- DHCx: The DHCx design uses thermally conductive coupling with the laptop and a solid aluminum heatsink carved with cooling fin air channels to extract heat from the laptop, as well as directing active airflow for flushing out hot air, cooling the laptop enclosure surface, and internally cooling processors on laptops that include a center intake vent.
- Dx: The Dx design uses active airflow for cooling the bottom surface of the laptop enclosure, as well as internally cooling processors on laptops that include a center intake vent.
- DHCx: 9 square inches of thermally conductive area for fitting with laptops that have a more round or curving edge, as well as a wider variety of laptops.
- Dx: No thermally conductive coupling occurs as airflow cooling of the laptop enclosure surface is used instead of conductive heatsink cooling, however, some radiant heat transfers to the solid aluminum dock.
- DHCx: 5 wide cooing fins and 4 wide vertical air channels for increased cooling airflow.
- Dx: No cooling fins are included as airflow cooling of the laptop enclosure surface is used instead of conductive heatsink cooling.
- DHCx: 27 square inches of cooling fin surface area.
- Dx: 6 square inches of cooling surface area with the interior air chamber and ten vent slots.
- DHCx: 2.0 pound heatsink carved from solid aluminum for improved heat movement through thermal mass.
- Dx: 1.8 pound carved solid aluminum.

- Sx: Angular styling with a single component base support made from formed anodized aluminum.
- SRx: The two upper support arms and two lower support legs have slightly oversized mounting holes to allow for small height adjustments, and the product ships with one set of levels pads for additional small height adjustments to both the upper arms and lower legs.
- Sx: The two upper support arms have slightly oversized mounting holes to allow for small height adjustments, and the product ships with one set of upper arm levels pads for additional small height adjustments. The solid aluminum support base has four threaded holes at the four corners of the lower horizontal panel. The product ships with four leveling fasteners with non-slip pads that can be installed fully recessed within the aluminum base’s thickness and then each can be independently deployed to level the base for small to larger height adjustments as required. The base’s threaded holes can also be used to bolt the Stand to a desk or mobile workstation.
- SRx: Cables can be fed through the gap under the anodized aluminum front mounting plate, as well as the sides through the gap under the support legs. The cables are then hidden from view and routed to the laptop along the inside of the upper support arms.

- SRx: The flat anodized aluminum mounting plate with separate support legs allows the individual components to fit within more compact and slimmer product packaging with locking lid for easier transportation.
- Sx: The heavier and larger solid anodized aluminum support base ships with the cooling system pre-installed and with the base bolted onto the product packaging. This allows the inner product packaging to also act as the outer shipping packaging, which reduces shipment size and shipping waste.
- SRx: $299 with 3rd generation laptop support arms.
- Sx: $279 with 2nd generation laptop support arms, and $299 with 3rd generation laptop support arms.
