Heatsink Launcher

Purges ship's heat into a disposable sink block, which is then ejected. Requires ammunition.

— In-Game Description

Heat sinks can be used to temporarily cool the ship by transferring all internally stored heat to a disposable sink and then ejecting the disposable sink from the ship.

Heat sinks are most commonly used in connection with Silent Running or with larger ships dumping excess heat when making multiple hyperspace jumps. With release of Horizons, heat sink launchers also became important to prevent overheating due to the use of shield cell banks.

Deploying a heat sink when weapons systems are overheated will also speed up the cool down process. The heat sink launchers are installed on a ship's Utility Mount and you can install more than one providing your ship has additional Utility Mounts to install them in. Each heat sink has a capacity of 3 sinks and each sink can hold approx 90-100% of the ship's maximum heat capacity. Heat sinks can be launched via a dedicated key binding or launched via the fire button of the fire group the launcher is assigned to. Hardpoints do not need to be deployed to launch a heat sink.

Heat sinks are now functional outside of normal space and can be used while in Supercruise.

Note that the key bound to "launch heat sink" does not always launch a sink while in Super Cruise. To work around this, use a fire button instead (assign it to a fire group before entering supercruise select the fire group prior to entering supercruise).

If you use fire groups to launch heat sinks, make sure each launcher is bound separately. Otherwise, every sink bound to that key will launch at once, depleting ammo.
