Heat sinks are devices that sap heat from components inside your computer, a compact heat sink would be the same device in a smaller fashion, designed to go in small form factor pc's the inherently don't have a lot of space.
heat sinks
Cold air is compact air Hot air is less dense than cold air Ergo, hot air rises ; cold air sinks
No, cold sinks and heat rises.
The main purpose of a heat sink is to expel heat from a generating source. Heat sinks work through the process of conductive and convection heat transfer. Heat sinks are a passive form of cooling, as they have no moving parts and require no power.
Some heat sinks are packaged as part of a processor chip. This is done to reduce costs and potential user error.

heat sinks
Because of convection: heat rises and cold sinks
The cleaning of heat pipes and sinks can be done with two different chemicals (among others). Highly purified Isopropyl alcohol and chemist grade acetone are two examples. That being said if the heat sinks and pipes are made of copper do not expose them to ammonia which can react.
Copper and aluminum. Most heat sinks are made of Aluminum (cheap and a good conductor of heat).
Heat sinks increase the rate of heat loss from the source into the environment, i.e. usually air. The heat goes to the same place as it would without the heat sink, it just does it quicker. Some heat sinks may be enclosed in a liquid, which is used to transport the heat elsewhere where it cools down and then returns.
