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.
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.

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.
