COMPARE

Before comparing product features and specifications below, let’s start with what SVALT products share in common.

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.

DHCR Cooling Dock $279 for 3rd gen
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.


DHC Cooling Dock $219 for 3rd gen
Silent Conductive Heatsink Cooling for Closed-Screen Laptops
The new 3rd generation DHC offers more affordable silent heatsink cooling performance for current and prior generation Apple laptops. The DHC features a thin thermally conductive interface to more effectively extract heat from the laptop and transfer it to a 2.3 pound heatsink carved from solid aluminum with 5 deep cooling fin air channels to create 72 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).

Compare DHC vs DHCx

Design

• 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.

• Sx: Angular styling with a single component base support made from formed anodized aluminum.

Leveling

• 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.
