DHCR SPECIFICATIONS


Cooling System Specifications
  • See Features for DHCR heatsink cooling system details.
  • See Product Setup page for product setup, operation and additional user guide resources. Please note that achieving cooling performance potential requires proper product and workstation setup.


Device Compatibility Specifications
  • Compatible Apple / Mac Laptops: The 4th, 3rd and 2nd generation DHCR models are compatible for cooling and fit with Mac laptop models from the last decade, as well as other devices per the compatibility criteria listed below. The 4th, 3rd and 2nd gen models are recommended for most laptops over the 1st gen model.
  • Compatible PC Laptops: Most standard to small PC laptops and other devices per the compatibility criterial listed below.
  • Compatibility Criteria for Types: Works with the following device and screen types: 1) Laptops operated in closed-screen clamshell mode while connected to an external display, keyboard/mouse and power supply. 2) Laptops with convertible/flip touchscreen, either while in a standalone configuration with touchscreen, or while also connected to a second display and/or keyboard/mouse. 3) Tablets with touchscreen, either standalone or connected to an additional display.
  • Compatibility Criteria for Fit: Works with devices that are up to approximately 1.100 inches thick, but will vary depending on the bottom edge shape of the device. An optional laptop retention pad can be installed to lock the laptop in place.
  • Compatibility Criteria for Cooling: Works with devices that do not have hot air exhaust vents located within the 4.800 inch center portion of the bottom edge (screen hinge edge on laptops), and that have a metal enclosure surface for coupling with the thermally conductive interface (note that customer installed surface coverings will not allow for thermal coupling and the transfer of heat from device to heatsink). Cooling performance improves with devices that have the following attributes, where more attributes result in more cooling: 1) Bottom/back metal enclosure surfaces that are flat at the location of the larger and taller thermally conductive pad to allow for continuous coupling and maximum heat transfer. 2) Processor location centered and near bottom edge to align the device’s highest temperature location with the most cooling for the largest heat transfer potential into the heatsink thermal mass. 3) Cool air intake vent locations centered on the bottom edge for direct internal cooling from the passthrough hole when used with the optional Cooling Fan Fx accessory. Note that the 3rd and 2nd generation DHCR models include curving cutouts in the front horizontal air channels for improved airflow and heatsink cooling with 2021-2023 MacBook Pros (M2/M1 Pro/Max).

Assembly Note
  • Some assembly may be required. Follow packaging labels and see Product Setup page for product setup, operation and additional user guide resources.


Heatsink Color and Finish Specifications
  • Lighter colors have a thinner anodize depth, which slightly improves heatsink conductive and convective heat transfer. In contrast, darker colors have higher heatsink emissivity, which slightly improves heatsink radiant and convective heat transfer.
  • Placing a heatsink in direct sunlight will result in heat gain and reduced cooling capacity. Lighter colors will have slightly less heat gain, while darker colors will have higher heat gain. Dark gray and black may have significant heat gain, to the point that it has a detrimental impact on cooling. See Workstation Setup page to learn more about how to setup your workstation to avoid heat gain.
  • Anodized parts are pre-finished by hand and then anodized by hand in small batches.
  • The same anodize color may vary slightly between individual parts based on where the part was located on the rack and whether the parts where run together on the rack or same batch.
  • Anodized part’s bottom and/or back surfaces are considered non-cosmetic finish.
  • Anodized surfaces can be cleaned with a damp cloth/sponge and soap.
  • See Order Configurations section for heatsink color options and additional details.


Heatsink Coupling Plate Specifications
  • The 4th generation DHCR is available with direct metal-to-metal laptop-to-heatsink coupling or with a protective thermally conductive assembly applied over the coupling plate.
  • The direct metal-to-metal laptop-to-heatsink coupling configuration requires extra care when setting up the laptop since the anodized aluminum surfaces of the laptop and heatsink will make direct contact.
  • The heatsink’s aluminum laptop coupling plate prioritizes functional performance and may not be as visually even and consistent as the rest of the heatsink’s aluminum heavy-texture bead-blast surfaces.
  • The ultra-thin thermally conductive assembly has a yellow-orange color hue that varies depending on the underlying anodized aluminum color with silver being the brightest and black being the darkest. A thinner material assembly improves heat transfer, and has a slightly lighter color compared to a thicker assembly.
  • The thermally conductive assembly is engineered and installed to prioritize technical performance over cosmetics, and may show small areas of lighter or darker color marks or areas of uneven coloring. Exposure to heat from device coupling may reduce or eliminate some marks or uneven areas over time.
  • A white microfiber cloth is provided to clean surface.
  • See Order Configurations section for laptop coupling plate options and additional details.
