What is the cooling on Surface Pro 3?

Surface Pro 3 relies on an internal fan and heat sink system for active cooling across all models.

Surface Pro 3 uses active cooling on every model. It has a single internal fan positioned next to the CPU that pulls heat through two connected heat sinks.

This design keeps performance steady under normal use and ramps up airflow when you push the device hard. You may hear the fan under heavy workloads, and you can add USB-powered fans or cooling pads for extra airflow.
