Heatsinks:

They are great for removing the heat away from the board. It is worth the $10.00 extra per board to have. Also great if you are pulling peak or near peak power from the board. What else do you want to know?


Internet info:

A heat sink is an environment or object that absorbs heat from another object using thermal contact (in either direct or radiant contact).

In common use, it is a metal object brought into contact with an electronic component's hot surface — though in most cases, a thin thermal interface material mediates between the two surfaces. Microprocessors and power handling semiconductors are examples of electronics that need a heat sink to reduce their temperature through increased thermal mass and heat dissipation (primarily by conduction and convection and to a lesser extent by radiation). Heat sinks are widely used in electronics, and have become almost essential to modern integrated circuits like microprocessors, DSPs, GPUs, and more.

A heat sink usually consists of a base with one or more flat surfaces and an array of comb or fin-like protrusions increase the heat sink's surface area contacting the air, and thus increasing the heat dissipation rate. While a heat sink is a static object, a fan often aids a heat sink by providing increased airflow over the heat sink — thus maintaining a larger temperature gradient by replacing the warmed air more quickly than passive convection achieves alone — this is known as a forced air system.

Scott covered it pretty well. I think that unless you have very specific plans to use very little power per channel then you should have heatsinks.

Do all of the 16-channel (30amp) Showtime controllers automatically come with the heat sink feature?

Yes....
