Workspace Setup
The following is provided to help achieve an optimal SVALT workstation setup:
  • Avoid Restrictive Spaces: If the back of SVALT Cooling Dock and laptop are placed against a wall or within a enclosed space (cabinet, shelving, under desk, etc), then the SVALT Cooling Dock’s intake may be restricted, which could result in reduced cooling power and increased noise levels. A restrictive placement could also result in the laptop’s hot exhaust being cycled back into the SVALT Cooling Dock’s intake, leading to less effective cooling.
  • 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 the SVALT Cooling Dock and laptop, identify the device’s hot exhaust vent and position it to blow in the other direction, or alternatively, move the Cooling Dock so that it is away from the heat exhaust. Note that Apple Thunderbolt Displays generate and exhaust a considerable amount of heat from the left portion of the bottom edge vent.
  • 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 SVALT Cooling Dock and laptop so it is not hit by the heated air. Also keep in mind that offices may reduce or disable air condition during non-business hours.
  • Avoid Direct Sunlight: The SVALT Cooling Dock and current Mac laptops are made of aluminum, a material that will absorb solar radiant energy when hit with direct sunlight. Low-E glass helps, but if you stand in the window and the sun feels warm, then the laptop is also getting nice and toasty. That heat will slow passive cooling at best, and at worst slowly cook internal components.

SVALT Cooling Dock Operation

The following explains how to operate a SVALT Cooling Dock based on model and firmware version:
  • SVALT D2 Operation with Cooling System Firmware Version 2.0
    (v2.0 included with D2’s shipped after August 7, 2017)

    System Startup & Shutdown
    A pushbutton switch is used to control the system and is located on the rear screen panel. A LED signals switch inputs and the system’s cooling mode (see Turbo and Custom Cooling Mode sections below for LED signal patterns). The LED is located inside the rear screen, along the bottom of the fan. The LED is positioned to be visible when leaning over the laptop and looking down the back side of the dock.
    • 1x Startup : To turn on the D2, press the push-button switch once (1x) and the cooling system will start in Auto cooling mode by default (see the Auto Cooling Modes section below to learn about how this cooling mode works, and see the Custom Cooling Modes section below to change cooling modes). When powering on the cooling system or changing cooling modes, the LED will signal the cooling mode for 24-seconds, while the fan provides an audio signal by instantly spinning to maximum speed and then either dropping down to a lower speed or turning off based on cooling mode and measured temperature.
    • 1x Shutdown : To turn off the D2, wait a few seconds if you just powered on the D2, and then press the switch once (1x) to power down the cooling system. When powering off the cooling system, the LED will momentarily light up and fade to off after 1-second, while the fan spins to a stop if it hasn’t already stopped.

    Auto Cooling Modes
    In any of the three Auto cooling modes the cooling system’s external thermistor measures laptop enclosure temperatures and automatically adjust fan speed between 900 and 3600 RPM. This helps keep things quiet when supplemental cooling is not required and then increase cooling power 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 it will automatically restart.

    Turbo Cooling Modes
    After turning on the D2 by pressing the switch 1x, you can then use the following switch activations to immediately increase fan speed to 3200 RPM for an extra blast of cooling power. These Turbo cooling modes are temporary and do not change the saved cooling mode.
    • 2x Turbo (rapid flashing LED) : When you press switch 2x the cooling system will enable Turbo and then automatically return to the default Auto cooling mode, or the last user saved cooling mode after 5-min.
    • 3x Turbo + (medium flashing LED) : When you press switch 3x the cooling system will enable Turbo until you press the switch 1x to return to the default Auto cooling mode, or the last user saved cooling mode.

    Custom Cooling Modes
    After turning on the D2 by pressing the switch 1x, you can then use the following switch activations to change the saved cooling mode. Once one of these modes has been enabled, then the D2 will return to that cooling mode upon subsequent power restarts.
    • 4x Fixed (slow flashing LED) : When you press the switch 4x the cooling system will run at a constant 1600 RPM fixed speed by default to provide a balance of audio and cooling performance, or you can save a custom fixed speed to precisely meet your audio and cooling performance requirements as described below in 5x Fixed Customization.
    • 5x Fixed Customization (LED pulses up and down to indicate rising or falling fan programming speeds) : When you press the switch 5x the fan will begin to continually cycle from 900 to 3600 to 900 RPM. Press the switch 1x when the fan reaches your desired fixed speed. At this point you have saved a custom fixed speed and entered into 4x Fixed cooling mode. If you change cooling modes and then return to 4x Fixed cooling mode, it will return to your custom fixed speed. If you would like to select a different fixed speed, then press the switch 5x to restart the process, or you can reset to the default 1600 RPM as described below.
    • 6x Auto + (rapid pulsing LED) : When you press the switch 6x the cooling system will run at higher speeds for cooling priority. In this cooling mode the fan is more likely to stay on at low to moderate speeds, and will increase speeds sooner to help stay ahead of heat buildup. This cooling mode is suggested for cooler offices.
    • 7x Auto (medium pulsing LED) : When you press the switch 7x the cooling system will run at default speeds for a balance of audio and cooling performance. In this cooling mode the fan will stay off or at lower speeds until temperatures rise, as which point fan speeds will progressively increase to help neutralize heat buildup. This cooling mode is suggested for offices with normal temperatures.
    • 8x Auto - (slow pulsing LED) : When you press the switch 8x the cooling system will run at lower speeds for audio priority. In this cooling mode the fan will stay off or at lower speeds until temperatures rise significantly, at which point fan speeds will rapidly increase to help recovery from heat buildup. This cooling mode is suggested for hotter offices.

    Restore Factory Defaults
    To reset the cooling system to factory default settings press and hold the switch for 5-seconds. Once the switch has been held down for 5-seconds and a system reset has been triggered, the fan will speed up and the system will enter into Auto default cooling mode and the LED will medium pulse. The Fixed cooling mode will also reset to 1600 RPM.

When powering off the cooling system, the LED will momentarily light up and fade to off after 1-second, while the fan spins to a stop if it hasn’t already stopped.

    Auto Cooling Modes
    In any of the three Auto cooling modes the cooling system’s external thermistor measures laptop enclosure temperatures and automatically adjust fan speed between 0 and 3600 RPM. This helps keep things quiet when supplemental cooling is not required and then increase cooling power 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 it will automatically restart.

    Turbo Cooling Modes
    After turning on the D2 by pressing the switch 1x, you can then use the following switch activations to immediately increase fan speed to 3200 RPM for an extra blast of cooling power. These Turbo cooling modes are temporary and do not change the saved cooling mode.
    • 2x Turbo (very fast flashing LED) Press switch 2x to enable, and then the system will automatically return to default Auto cooling mode, or the last user saved cooling mode after 5-min.
    • 3x Turbo + (fast flashing LED) Press switch 3x to enable, and then press switch 1x to return to default Auto cooling mode, or the last user saved cooling mode.

    Custom Cooling Modes
    After turning on the D2 by pressing the switch 1x, you can then use the following switch activations to change the saved cooling mode. Once one of these modes has been enabled, then the D2 will return to that cooling mode upon subsequent power restarts.
    • 4x Fixed (medium flashing LED) Press switch 4x to set the cooling system to a fixed speed of your choosing. The fan continually cycles from 900 to 3600 to 900 RPM, while the LED indicates increasing or decreasing speeds. When the fan reaches your desired speed, press the switch 1x to select a fixed speed, at which point the LED will medium flash. Press switch 4x to restart the selection process. In this Fixed cooling mode you can lock-in the precise fan speed that provides the right balance of audio and cooling performance for your requirements.
    • 5x Auto - (slow fading LED) Press switch 5x to set the cooling system to a lower speeds for audio priority, or for a hot office as compared to normal 70 F office temperatures. In this Auto cooling mode the fan will stay off or at lower speeds until temperatures rise significantly, at which point fan speeds will rapidly increase to help recovery from heat buildup.
    • 6x Auto + (fast fading LED) Press switch 6x to set the cooling system to a higher speeds for cooling priority, or for a cold office as compared to normal 70 F office temperatures. In this Auto cooling mode the fan is more likely to stay on at low to moderate speed, and will increase speeds sooner to help stay ahead of heat buildup.
    • 7x Auto (medium fading LED) Press switch 7x to reset the cooling system to factory default for a balance of audio and cooling performance in normal 70 F office temperatures. In this Auto cooling mode the fan will stay off or at lower speeds until temperatures rise, as which point fan speeds will progressively increase to help neutralize heat buildup. The system can also be reset to factory default by pressing the switch 1x and then holding it down for 7-seconds, at which point the fan speeds up to signal a system reset.
