us to upgrade your D2’s cooling system firmware to Version 2.0. If you cover shipping costs, then we will upgrade the firmware and clean your Cooling Dock at no charge.
The following outlines Version 2.0's main revisions over Version 1.0:
D2 Pro Operation Firmware Version 1.0
- 4x Fixed cooling mode has been revised to start with a default 1600 RPM fixed speed or a user’s saved custom fixed speed.
- 5x Fixed Customize cooling mode has been added as a separate mode for the user to select a custom speed for 4x Fixed cooling mode. This allows the cooling system to save the user’s custom fixed speed so that it can be reactivated without having to reselect a fixed speed, which can be helpful when a user wants to change between modes to meet various audio or cooling performance scenarios.
- 6x Auto + cooling mode has been revised with significantly more aggressive mapping.
- 7x Auto default cooling mode has been revised with slightly more aggressive mapping.
- 8x Auto - cooling mode has been revised with slightly less aggressive mapping.
- The reset to factory default has been revised to reset Fixed cooling mode to the default 1600 RPM.
- The order of cooling modes has been revised along with associated switch activations required to enable the cooling modes.
Firmware version 1.0 was included with D2 Pro’s shipped before 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.
Auto Cooling Modes
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.
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.
Custom Cooling Modes
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.
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.
