Cooling kit

This is an add-on for certain Vertical Dock models to deliver active external cooling to minimize CPU and GPU thermal performance throttling.

While peak performance is not improved, sustained performance is far more consistent with external cooling especially for gaming or other 3D-graphics intensive workloads. The fan is aimed along the center of rear chassis where the CPU/GPU is located for maximum cooling effect.

• We cannot guarantee any particular performance improvement on your system, but we have observed 20-30% gains in sustained CPU+GPU package power draw when running a Furmark stress test on a Pro 4 Core i5 (9.5W -> 12.5W) at ~20°C ambient temperature. On a Surface Go, sustained package power increased from 6W->8W.
• Fan speed must be adjusted slowly. When the fan speed controller is set to maximum or adjusted quickly, fan noise may increase without additional airflow.
• At full speed, the fan is loud - approaching ~40 dBa, but you only need to run the fan at 30-50% speed to get decent cooling performance.
