The cooling fins and cooling air channels run continuously from front-to-back with an upward angle to generate passive cooling air currents through the entire heatsink. Open space under the heatsink supplies cool air for more effective silent passive cooling, as well as open space for fan driven active airflows.


SVALT MxS-h bottom view, rendering
MxS-hi bottom view, rendering.

The heatsink’s side support mounting points use 0.125 inch extra-thick pads to create an air gap between the heatsink and side supports. This air gap allows for open cooling airflow around the sides of the heatsink. The air gap and extra-thick pads work together to provide thermal separation between the heatsink, side supports, and exposure to hot exhaust air.


ACTIVE AIRFLOW FAN COOLING

The Mx product line uses a right-to-repair modular system that is designed to endure, and ships with all of the tools required for disassembly to clean, service, replace, upgrade or otherwise exercise right-to-repair usage.

The Mx is available with hundreds of configurations for the initial purchase, as well as reconfiguration after purchase through available modular components and accessories to give customers a wide range of options to best meet their current and future laptop workstation needs.

The Mx’s modular components are made of high-quality materials, such as anodized 6061-T6 aluminum, and are oversized for increased strength and longer life span. Component connections use extra-large fasteners for increased strength and increased durability over repeated reconnections.

The Mx product line was designed for silent heatsink cooling without the need for electric power, however, the Mx was also designed for use with a fan cooling system. Mx models can be configured with a variety of modular right-to-repair fan systems, or customers can provide their own DIY fan system. Each Mx fan system uses high-end fans with long life bearings, standard available fan sizes, standard bolted assemblies, and standard snap connectors for modular power, on/off and speed-control components.

Mx modular components and accessories are available to order separately through the Mx Components and the Fx Cooling Fan accessory product pages. Future modular components for the Mx product line are in development, such as wood side supports that feature solid milled wood construction, robust strength, leveling pads and cable clutter management.


MODULAR PACKAGING SUSTAINABILITY

Mx heatsink and side support modular packaging system exploded view, rendering.

The Mx product line’s bolted modularity extends to the packaging system that uses a single exterior cardboard box, modular cardboard insert layers and heavy duty bolted connections for increased protection, durability and sustainability. The bolted assembly protects components from contact with one another and holds the components away from external impacts.

A single cardboard box serves as both the product and shipping box, thus eliminating the additional waste of having a separate outer shipping box with additional interior volume fill and cushioning. Within the Mx’s single shipping and product box, folded cardboard inserts bolt onto each side of the heatsink. Cardboard accessory boxes are located inside the heatsink’s folded cardboard inserts and use paper envelopes to hold small items. The side supports bolt onto flat cardboard inserts that stack up with double and triple side support configurations.


RECYCLING SUSTAINABILITY

Other Devices
  • The Mx is compatible with many other laptops, tablets and devices per the Compatibility Criteria below.

Compatibility Criteria
The Mx is a fully modular system built around the core heatsink component. The top of heatsink has an extra large coupling plate for direct metal-to-metal coupling with a device’s metal enclosure/chassis to thermally conduct heat from the device and into the heatsink. For device compatibility with the Mx modular heatsink cooling system, all of the following compatibility criteria must be met:
  • Metal Coupling: For proper heatsink coupling and maximum thermally conductive heat transfer, the back/bottom of the device should have a metal enclosure/chassis and should not have a protective cover/case installed over or on top of the metal surface.

  • Flat Coupling: For proper heatsink coupling and maximum thermally conductive heat transfer, the back/bottom of the device should have a flat metal surface free of pads, bumps and protrusions within the heatsink’s coupling area.

  • Coupling Area: For proper heatsink coupling and maximum thermally conductive heat transfer, the back/bottom of the device should have flat metal surface that is at least 6.750 inches front-to-back and 5.950 inches side-to-side. A smaller area can work with a device that is smaller than the heatsink and meets other compatibility criteria.

  • Air Vents: If the device has a built-in air cooling system, then the device’s vent locations and their direction of airflow needs to be considered, such as the following: 1) The device’s vents should not be covered by the heatsink’s coupling area. 2) The device’s hot exhaust vents should not blow directly onto the heatsink.

  • Fit w/ Dock Supports: The Dock Supports position the heatsink above the device’s bottom edge by approximately 0.430 inches.

  • Fit w/ Stand Supports: The High/Low Stand Supports have four heatsink mounting options, and position the heatsink from the device’s front edge by approximately 2.700 inches for position 1, 2.150 inches for position 2, 1.600 inches for position 3, and 1.050 inches for position 4.

The Mx product line was designed to exceed all prior models with extreme cooling capabilities. The Mx's massive thermally conductive heatsink silently pulls heat from the laptop to help reduce laptop temperatures and quiet laptop built-in fans. The Mx’s optional fan cooling system helps tackle extra high-intensity and long-duration workloads.


Test Results

SVALT product cooling and audio performance shown in the graph above is approximate and based on a wide range of averaged and normalized testing. SVALT conducts a variety of tests through conceptual research, product development and final production proving phases. Test results are meant to provide a more general understanding of built-in laptop cooling systems and how they respond to supplemental cooling. Actual results vary depending on a SVALT product’s configuration, fan, fan speed setting, laptop model, laptop configuration, laptop operation, workstation setup, external monitor setup, and overall testing conditions.


Test Laptop Operation

Mx tests conducted with the laptop in closed-screen operation while connected to a single low-resolution external monitor. Comparison tests conducted with the screen open and without an external monitor for high and low stand models.

  • As a general condition for all laptop models, adding a high-resolution external monitors and/or multiple external monitors will increase demand on the laptop and generate more heat. Demand and heat generation can be reduced by using only the laptop’s built-in display, or by closing the built-in display and connected to a single low resolution external monitor.

  • As a general condition for 2021+ MacBook Pro, the laptop runs cooler when in closed-screen operation and connected to a single low-resolution external monitor as compared to using a single high-resolution monitor, multiple monitors, or running in open-screen operation. As a result of the 2021+ MacBook Pro's back edge hinge venting design, these laptops are among a small group of laptops that do not see a large reduction in temperatures when the screen is open, or conversely, are particularly capable when running in clamshell mode.

Test Model Configurations

Mx tests conducted with multiple Mx model configurations.

  • As a general note, results were more similar than dissimilar between the different Mx model configurations. When selecting a Mx model, it is recommended to select a model based on a desired workstation setup, such as the dock supports to position the laptop upright with screen closed and moved aside to free up desk space, the high stand supports to use the built-in display and have it raised higher for improved viewing ergonomics, or the low stand supports to have a low-profile setup with the screen closed or with the screen open to type directly on the laptop keyboard.

  • Silent heatsink cooling is approximately consistent across the three side supports

  • Fan active airflow cooling with the heatsink is approximately consistent across the 140mm bolt-on and 80mm Fx separate fan cooling system configurations.

  • The following slight differences in cooling between side support and fan system configurations were observed:

    • For all laptops and devices, the low and high stand supports have a near horizontal laptop support orientation, which allows the weight of the laptop to press down onto the heatsink’s conductive coupling plate, which in turn increases conductive heat transfer between the laptop and heatsink.

    • For all laptops and devices, the 140mm fan's larger size allows the fan to generate slightly more airflow for a given amount of noise generation. The 140mm fan's larger size also allows the fan to span the full width of the heatsink and nearly span the full length, which moves more cooling air over/through the heatsink cooling fins and removes more heat from the heatsink.

    • For the 2021+ MacBook Pro and other laptops that include a center intake vent along the back/hinge edge, the low stand supports with FxB22 Cooling Fan provides slightly more cooling because the low stand supports have increased heatsink conductive coupling, and because the low stand positions the laptop’s center intake vent so that the Fx Cooling Fan can simultaneously cool the heatsink and drive air into the laptop for direct internal processor cooling.

Test Conditions

Mx tests conducted per SVALT’s testing guidelines that control testing conditions.
