      SVALT Cooling Dock model D2/D1 Pro D2/1 Pro Cooling System
      The D2 Pro and D1 Pro use a passive and active cooling system. The passive cooling system features a 1.8 pound aluminum heat sink located next to laptop processors that absorbs heat through line-of-sight radiant heat transfer. The active cooling system features ten side vents that drive cooling air onto the laptop’s metal enclosure at the processor location and then sends cooling airflow to the sides of the laptop enclosure. The side vents combine with cooling airflow from a lower vent that drives cooling air at the laptop enclosure’s central processor location and then sends air upward along the laptop enclosure. Raised laptop pads direct airflow for optimal cooling, as well as house the D2’s laptop temperature sensor. Pad size is minimized to reduce contact area on the laptop, reduce heat trap and maximize cooling. The managed airflow helps generate more efficient and quieter cooling.

      The D2 Pro’s active cooling system uses a powerful and high-quality 12-volt fan to efficiently generate more cooling airflow with less noise. The system operates with a programmable speed control that includes an external thermistor to measure the laptop enclosure temperature and to automatically adjust fan speed between over the course of a workday. Three Auto mode presets help to meet a variety of user needs and conditions, a Fixed speed cooling mode can be customized to any speed for complete user control, and two temporary Turbo cooling modes offer an instant blast of cooling power. A momentary push-button switch allows for user cooling system configuration, while a LED signals cooling system settings.

      The D2 Pro is available with either a standard D2 cooling system that prioritizes high-speed cooling performance for maximum cooling potential or a D2n cooling system that prioritizes low-speed audio performance for noise critical environments. The D2 cooling system uses a 800-4200 RPM speed range that delivers significant cooling airflow (up to 50 CFM and 75 Pa) with high noise levels at max-speed (up to 50 dBA). The D2n cooling system uses an ultra quiet Noctua fan that delivers cooling airflow (up to 37 CFM and 23 Pa) with quieter operation at overlapping 800-2200RPM speeds (up to 18 dBA) and with essentially silent operation at lower 500-1200RPM speeds. Both D2 fans have 7 black blades with a long life ball bearing and approximately eight years of continuous operation.

      The D1 Pro’s active cooling system uses a powerful and high-quality 12-volt fan to efficiently generate more cooling airflow with less noise. The system operates with a single-speed for simple on/off push-button switch operation. The fan runs at approximately 1700 RPM for a balance of audio performance at 17 dBA and cooling performance at 30 CFM. The fan has 7 red blades with a long life ball bearing and approximately eight years of continuous operation. Note that the D1 Pro uses a manual latching on/off power switch that allows the power supply to be plugged into a timer or smart home outlet. This gives the user the ability to automatically start/stop the cooling system per a set schedule, room ambient temperature, laptop sleep/wake or power status, etc.

      All three models use a modular cooling system that allows for exchanging cooling systems, as well as easier servicing and maintenance.

      


      SVALT Cooling Dock model D1 Legacy D1 Legacy Cooling System
      The D1 Legacy uses a passive and active cooling system. The passive cooling system uses a 1.9 pound aluminum heat sink located next to laptop processors for heat absorption. The active cooling system uses a lip edge to create an air seal around compatible laptops with a center air intake vent (see compatibility tab). The fan drives cooling air through the laptop vent to directly cooling internal components, such as processors, and then flushes out hot internal air through the laptop’s exhaust vents.

      The D1 Legacy’s active cooling system uses a powerful and high-quality 12-volt fan to efficiently generate more cooling airflow with less noise. The system operates with a single-speed for simple on/off push-button switch operation. The fan runs at approximately 1700 RPM for a balance of audio performance at 17 dBA and cooling performance at 30 CFM. The fan has 7 red blades with a long life ball bearing and approximately eight years of continuous operation. Note that the D1 Legacy uses a manual latching on/off power switch that allows the power supply to be plugged into a timer or smart home outlet. This gives the user the ability to automatically start/stop the cooling system per a set schedule, room ambient temperature, laptop sleep/wake or power status, etc.

      


      SVALT Cooling Dock model D D Cooling System
      The D uses a passive cooling system with a massive 3.3 pound aluminum heat sink located next to laptop processors for heat absorption. The heat sink works in conjunction with a cooling air channel and hole that generates natural air currents to exhaust heat from laptop and dock. The air within the air channel located between the laptop, dock and vertical pads heats up and exhausts upward out the open top edge, while pulling cool air from behind the dock through the center cooling air hole.

If the laptop is powered on and asleep, then leave the laptop screen closed and press the external keyboard’s space bar to wake up the laptop.
      • Please see our clamshell setup guide for additional details on clamshell setup and operation

      

      All Models Workspace Setup
      • Avoid Restrictive Spaces: Locate the computer away from walls and corners for access to more air circulation and avoid trapping hot air that could be pulled back into intake vents. Avoid placing within a small enclosed space (cabinet, shelving, under desk, etc) without a dedicated mechanical air conditioning system (like a server room). Provide a recommended 6 inch minimum and 12 inch preferred open space behind and on the sides of the Cooling Dock with laptop. Reductions in this open space area will result in reduced cooling efficiency and increased noise.
      • Avoid Heat Sources: External displays, hard drive arrays, and other common professional desktop accessories can generate and exhaust heat. To avoid transferring that heat to your computer, identify the neighboring device’s hot exhaust vent and position it to reduce heat transfer. Provide a recommended 6 inch minimum and 12 inch preferred separation from heat source on all sides of the Cooling Dock with laptop. Reductions in this open space area will result in reduced cooling efficiency.
      • Avoid Hot Spaces: As a general rule, an increase in ambient air temperature will lead to higher computer temperatures. If your office space has forced air heating, then try to position the computer so that it is not hit by heated air. Of course, the reverse is true with air conditioning, as that airflow could help drop ambient air temperature.
      • Avoid Direct Sunlight: When metal is placed in direct sunlight then it will absorb heat, which will reduce it’s heat sink cooling capabilities and could result in heat radiating into the computer.

      D2 Pro Operation
      The following operation guide is for the new next generation D2 Pro model with firmware version 3.0 (September 2020), and the D2n Pro model with firmware version 4.0 (November 2020). For the original D2 Legacy models with firmware versions 1.0 and 2.0, please go to the operation and upgrades.

      Cooling System Components
      The following describes the cooling system’s major user interface components:
      • Jack : A power jack located towards the bottom of the rear screen receives a power supply plug for powering the system. Only use the power supply included with product shipment or a Replacement Power Supply.
      • Switch : A pushbutton switch located towards the bottom of the rear screen panel controls the system. After starting the cooling system as described below, pressing the switch two times (2x) to eight times (8x) will enable different cooling modes and additional functionality as described below. To register multiple switch entries, each switch depression needs to occur within 1.2 seconds of the last.
      • LED : A LED located inside the rear screen and toward the bottom indicates switch inputs and the system’s enabled cooling mode. When starting up the cooling system or changing cooling modes, the LED will indicated the enabled cooling mode for 24-seconds (see Turbo and Custom Cooling Mode sections below for LED signal patterns). When shutting down the cooling system, the LED will momentarily light up and fade to off after 1-second. The LED is placed for visibility when leaning over the laptop and looking down the back side of the dock.
      • Fan : A fan located behind the rear screen generates cooling airflow by pulling air from the back and drive it out the front vents against the laptop enclosure. The fan also provides an audio indicator for switch inputs and the system’s enabled cooling mode. When starting the cooling system or changing cooling modes, the fan instantly spins up to maximum speed and then either drops down to a lower speed or turns off based on the cooling mode and measured temperature. When shutting down the cooling system, the fan will stop if it hasn’t already stopped.
      • Thermistor : A thermistor located within the top laptop pad measures laptop enclosure temperature in order to automatically adjust fan speeds when one of the three Auto cooling modes are enabled.

      

      

      System Startup & Shutdown
      The following single 1x switch activation provide basic cooling system on/off operation.
      • 1x Startup (LED flashes per enabled cooling mode as indicated below) : When the cooling system is shutdown, pressing the switch 1x starts the cooling system in Auto cooling mode by default or the last user saved cooling mode as described below.
      • 1x Shutdown (LED fades to off) : After waiting 2-seconds from the last switch depression, pressing the switch 1x shuts down the cooling system.

      Auto Cooling Modes
      The cooling system runs in Auto cooling mode by default. In addition to the default Auto cooling mode, there are also Auto+ and Auto- cooling modes to help meet different conditions and user preferences. In any of the three Auto cooling modes the cooling system’s external thermistor measures laptop enclosure temperatures and automatically adjust fan speeds. This helps keep things quiet when supplemental cooling is not required and then increases fan speed as temperatures rise over the course of a workday. When temperatures are low enough the fan will temporarily stop until higher temperatures are detected, at which point the fan will automatically restart. See the Custom Cooling Modes section below to learn more about each of the three Auto cooling modes.

      Turbo Cooling Modes
      After starting the cooling system as described above, then the following switch activations will immediately increase the fan speed for an extra blast of cooling power. The Turbo cooling modes are temporary and do not change the last saved cooling mode, and so are meant to be used in conjunction with a user’s preferred normal cooling mode.
      • 2x Turbo (rapid flashing LED) : Pressing the switch 2x runs the fan at 2400 RPM for D2 Pro and 2200 RPM for D2n Pro until automatically returning to the default Auto cooling mode or the last user saved cooling mode after 30-minutes for D2 Pro and 10-minutes for D2n Pro. Turbo cooling mode provides a moderate increase in fan speed while maintaining moderately low noise levels for a quick boost in cooling power.
      • 3x Turbo+ (medium flashing LED) : Pressing the switch 3x runs the fan at 4200 RPM for D2 Pro and 2200 RPM for D2n Pro until pressing the switch 1x to return to the default Auto cooling mode or the last user saved cooling mode. Turbo+ cooling mode provides maximum fan speed with high noise levels for a full boost in cooling power.

      

      

      Custom Cooling Modes
      After starting the cooling system as described above, then the following switch activations will change the saved cooling mode. Once one of these modes has been enabled, then the cooling system will return to that cooling mode upon subsequent power restarts or after the use of a temporary Turbo cooling mode.
      • 4x Fixed (slow flashing LED) : Pressing the switch 4x runs the fan at 1400 RPM for D2 Pro and 1200 RPM for D2n Pro by default or a user’s saved custom fixed speed (see 5x Fixed Customization below). Fixed cooling mode provides a constant speed for precisely meeting a user’s cooling and audio performance requirements.
      • 5x Fixed Customization (LED pulses up and down to indicate rising or falling fan programming speeds) : Pressing the switch 5x runs the fan in a cycle from the lowest to highest to lowest speed that repeats four times until pressing the switch 1x at the desired fixed speed. The cooling system automatically enters into the Fixed cooling mode at the selected and now saved speed. To select a different speed, then press the switch 5x to restart the process, or reset to the default speed as described below.
      • 6x Auto+ (rapid pulsing LED) : Pressing the switch 6x runs the fan at variable speeds set for cooling priority. Auto+ cooling mode is less likely to turn off in standby mode, to stay on at moderate speeds, and to increase speeds sooner to help stay ahead of heat buildup. Auto+ cooling mode is suggested for cooler offices or for more aggressive cooling within less noise sensitive environments.
      • 7x Auto (medium pulsing LED) : Pressing the switch 7x runs the fan at default variable speeds set for a balance of audio and cooling performance. Default Auto cooling mode is more likely to stay off in standby mode or run at lower speeds until temperatures rise, at which point fan speeds will progressively increase to help neutralize heat buildup. Auto cooling mode is suggested for offices with normal temperatures and normal noise sensitive environments.
      • 8x Auto- (slow pulsing LED) : Pressing the switch 8x runs the fan at variable speeds set for audio priority. Auto- cooling mode is most likely to stay off in standby mode or run at lower speeds until temperatures rise significantly, at which point fan speeds will begin to increase to help recovery from heat buildup. This cooling mode is suggested for hotter offices or more noise sensitive environments.

      Restore Factory Defaults
      After starting the cooling system as described above, the cooling system can be reset to factory default settings by pressing and holding the switch for 5-seconds. Once the switch has been held down for 5-seconds and a system reset has been triggered, then the fan will speed up and the system will reset to the default Auto cooling mode and the LED will medium pulse. The Fixed cooling mode will also reset to the default speed.

      Laptop Builtin Cooling Systems
      Compatibility is based on SVALT’s supplemental cooling system working with and boosting a laptop’s builtin cooling capabilities. To better understand how Apple laptop’s builtin cooling systems work and how SVALT products improve laptop performance, please see our article on Laptops.

      D2/1 Pro and D Compatibility
      The Cooling Dock models D2/1 Pro and D are optimized for supporting and cooling current generation Mac laptops, such as the 16-inch MacBook Pro. They are compatible with current and prior generation Mac laptops, as well as most all PC laptops. A steeply angled laptop support shelf and non-slip pad help to create a universal laptop support. A user installed laptop stop pad can be installed to lock a particular laptop in place, and each product ships with three pads for future laptop fit. See compatibility notes below for additional details.

      D1 Legacy Compatibility
      The original Cooling Dock model D1 Legacy was designed to drive cooling air through a laptop’s central air intake vent that becomes exposed and accessible when the screen is closed in clamshell mode. This configuration allows the laptop’s internal components, such as the processors, to be directly cooled and to turbo charge the laptop’s performance potential without requiring any laptop modification. The original D1 Legacy was designed for optimal performance with the 2012-2015 MacBook Pro and 2008-2017 MacBook Air laptops and select PC laptops with a center intake vent. Apple removed the central intake vent from current generation Mac laptops (2016+ MacBook Pros, 2018+ MacBook Airs, and 2015+ MacBooks), which removed the ability to internally cool processors. The D1 Legacy’s leaning support and adjustable retention pad help accommodate a range of laptops. See compatibility notes below for additional details.

      

      

      
All Models Device Compatibility Criteria
      The Cooling Dock can work with a wide range of devices. Devices may be compatible if they meet following screen, fit/alignment and cooling criteria.

      Screens
      Compatible devices can be used with a variety of screen configurations, such as the following:
      • Laptops operated in closed-screen clamshell mode while connected to an external display and keyboard/mouse.
      • 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.
      • Tablets with touchscreen, either standalone or connected to an additional display.

      Fit and Alignment
      Compatible devices with a range of thicknesses and shape can fit, based on the following:
      • All models of the Cooling Dock use a leaning vertical configuration to hold the device in place. The Cooling Docks have been designed for a device to be centered and placed on edge within the padded leaning cradle. While devices can be placed into the cradle off-center to align with a laptop’s off-center vent locations, doing so may compromise stability.
      • The D2/1 Pro and D models include a cradle shelf/foot with a steeper incline angle and uses a super grippy non-slip pad material to hold the laptop in place without the need for a locking pad as with the original D1 Legacy model. However, user installed laptop retention pads are included as an optional accessory for the user to install and lock the laptop in place. The model D will accommodate devices that are up to approximately 0.800 inches thick at their bottom tapped edge with the locking pad installed and 1.100 inches without the locking pad. The models D2/1 Pro will accommodate devices that are up to approximately 0.670 inches thick at their bottom tapped edge with the locking pad installed, 0.850 inches without the locking pad, and the user has the option to remove an outer layer of vertical padding to increase those figures by 0.063 inches.
      • The D1 Legacy model includes a front pad that adjusts to fit devices that are up to approximately 0.5 inches thick at their bottom tapped edge, and depending on the edge shape can fit devices up to approximately 0.9 inches thick at their thickest section. Larger devices with more rounded and tapered edges usually fit more easily than square edges. Adding a protective or decorative case to your device typically increases overall thickness and alters edge profile. Cases may or may not be compatible, with thinner cases more likely to fit than thicker cases. Note that removing the front adjustable pad allows thicker devices to lean against the cradle’s angled back and rest on the cradle’s lower pad. However, the laptop support shelf/foot on the original D1 Legacy model has less of an incline and less material grip than the new D2/1 Pro and D models, so the front adjustable pad on the original D1 Legacy is used to help hold the laptop in place and removing it may compromise stability.

      

      
Cooling
      Compatible devices can benefit from a variety of supplemental cooling configurations, based on the following:
      • All models of the Cooling Dock include a cooling vent hole in the center of the dock that is meant to align with a central cooling air intake vent located along the bottom/back edge of the laptop’s screen hinge. Laptops that exhaust hot air through a central vent located along the bottom/back edge of the laptop’s screen hinge will result in inefficient cooling that could result in higher laptop temperatures. This is a less common venting layout and cooling system design, but in these cases, the laptop may need to be positioned off-center so that the hot air exhaust vent is moved off of the dock. While devices can be placed into the cradle off-center, doing so may compromise stability.
      • The D model has been designed to provide passive cooling through a massive 3.3 pound heat sink that pulls heat from the laptop at the location of heat generating processors, along with an air hole and air channel to create passive cooling air currents. The passive cooling system has been designed to work optimally with all modern Mac laptops and to work with most any laptop venting layout and cooling systems.
      • The D2/1 Pro models have been designed to provide passive and active cooling. The passive cooling system uses a 1.8 pound aluminum heat sink located next to laptop processors in order to extract processor heat through the laptop’s aluminum enclosure by radiant heat transfer. The active cooling system uses ten slot vents and one large lower vent to drive cooling airflow against the laptop’s aluminum enclosure at the processor location and send cooling airflow over the rest of the laptop’s bottom surface.
      • The original D1 Legacy model has been designed to drive cooling air from its exhaust vent into a device’s air intake vent centrally located along the bottom edge. The original D1 Legacy’s cooling exhaust vent includes a flexible edge that conforms around the device’s edge to fit a greater variety of device shapes and provide an air seal around the device's air intake vent. The vent opening is approximately 3.8 inches wide at it widest point and approximately 0.5 inches tall at its tallest point. To achieve successful vent coupling, the device’s vent should be approximately as long as the original D1 Legacy’s exhaust vent, and should not conflict with the device’s exhaust venting. Devices with an intake vent that leads directly to the processors may result in more significant supplemental cooling.

      Introduction to Testing
      Computer processors generate heat which can increase temperatures, and when running intensive applications that heat can cause throttling and limit performance. Supplemental cooling can only increase performance under throttling conditions, however, the computer uses throttling to reduce temperatures and reduce heat damage. That means supplemental cooling that effectively improves cooling will allow the computer to run with reduced throttling and increased performance, but that also means that temperatures could be higher because of the higher processor power. In short, less throttling means faster and hotter. So if throttling occurs, then it is challenging to simultaneously test temperatures. Conversely, if throttling is not occurring, then it is impossible to test performance. For this reason, each test is conducted to analyze either temperatures or performance, and not both.

      To test supplemental cooling and to accurately measure its influence on temperatures and performance, SVALT tests under strictly controlled variables so that SVALT supplemental cooling is the only variable influencing the results. Each test session includes two tests, one with the SVALT supplemental cooling device and another without as the control. Conditions are as close to identical as possible for both tests (ambient air temperature, physical placement, non-thermally conductive insulated base, starting laptop temperatures, internal fan speeds, eliminated non-test background activities, and single applied testing workload) and results are based on direct sensor data logs (component temperatures, processor power and speed, etc). To learn more about throttling and our testing process see:
      

      D2 Pro Testing Details - All Tests
      • Computer: 2019 16-inch MacBook Pro (top-spec 2.4GHz CPU and 8GB GPU) with the screen closed running in clamshell mode, connected to a low-resolution external monitor, external keyboard/mouse, a fully charged battery, running on an Apple power adapter, and setup per Testing Guide.
      • Process: Two tests were conducted under controlled conditions per Testing Guide, a SVALT test with a Cooling Dock model D2 Pro set to Turbo+ 4200 rpm fan speeds, and another CONTROL test without the D2 Pro. Both tests were conducted on a flat non-thermally conductive insulated base and surrounded by open space without influence by an external cooling or heating source.
      • Ambient: Testing was conducted in a single room without windows closed and covered, and mechanical system dedicated to conditioning only that single space. The mechanical system was used to maintain a constant 75F temperature throughout testing. Temperatures were monitored by multiple gauges placed around the laptop and outside of any direct heating or cooling source.
      • Data: Overall setup photos were taken throughout the testing process to document testing conditions. Terminal automated screenshoots were captured every five minutes. Raw data from the laptop sensors was logged to CVS files through TG Pro and Intel Power Gadget applications. These data logs were used to calculate cooling performance by averaging data into 15-min segments, which were then used to generate the graphs and to calculate percentage improvements relative to the computer’s baseline settings.

      D2 Pro Testing Details - Light Stress Test
      • Summary: The SVALT test had up to 87% cooler processor (CPU Proximity in Celsius) and up to 67% cooler processor (AMD Radeon Pro 5500M Proximity in Celsius) compared to the CONTROL test.
