because metal is a good conductor of energy (there are a lot of free electrons in a metal) and this will cause the metal to absorb and radiate more energy combined with the increased surface area of the heat sink

no, the type of metal used is platinum which is unfavorable to metal or magnet.
Heat sinks are needed for transistors passing large currents. Waste heat is produced in transistors due to the current flowing through them. If you find that a transistor is becoming too hot to touch it certainly needs a heat sink! The heat sink helps to dissipate the heat by transferring it to the surrounding air. The rate of producing waste heat is called the thermal power, P. Usually the base current IB is too small to contribute much heat, so the thermal power is determined by the collector current IC and the voltage VCE across the transistor: P = IC × VCE The heat is not a problem if IC is small or if the transistor is used as a switch because when 'full on' VCE is almost zero. However, power transistors used in circuits such as an audio amplifier or a motor speed controller will be partly on most of the time and VCE may be about half the supply voltage. These power transistors will almost certainly need a heat sink to prevent them overheating. Power transistors usually have bolt holes for attaching heat sinks, but clip-on heat sinks are also available. Make sure you use the right type for your transistor. Many transistors have metal cases which are connected to one of their leads so it may be necessary to insulate the heat sink from the transistor. Insulating kits are available with a mica sheet and a plastic sleeve for the bolt. Heat-conducting paste can be used to improve heat flow from the transistor to the heat sink, this is especially important if an insulation kit is used.
Annealing is a term used for when metal is heat hardened

A Fan sink is a Heat sink with a fixed FAN. Heat sink's are blocks of metal, primarily used are are copper, and aluminum, that draw heat from a source ( such as your Processor, or another heat producing chip set ) and spread it across its surface area to be air cooled. A Fan sink, combine's the heat drawing of it's sink with a dedicated fan blowing air into ore out from the heat sink below it. This will significantly improve the sinks cooling power. So a processor cooler is most likely a Fan sink, but some chips surrounding it may only have a heat sink. ( Southbridge controller is usually placed near your CPU and is fitted with a black block of metal that has a lot of blades on it )
Either a cold plate, used with Peltier, or TEC (Thermo Electric Cooling) or a water block used with water cooling systems.
Heatsinks and fans are used on CPUs to help cool them down so that they are not destroyed. A heatsink is a piece of metal placed on the CPU to distribute heat away from the CPU itself.
Heat sink
A heat sink is designed to disperse and transfer heat coming from a processor to an outside medium, so that it does not overheat the actual processor chip. It is usually used in conjunction with a fan to cool the device it is installed on.
There is no such thing as the "purity of electrons". A heat sink is used to keep a device reasonably cold.
A heat-sink is needed to dissipate the wasted power without any undue temperature rise. The effectiveness of a heat sink is measured by the watts dissipated per degree of temperature rise.
Not sure what a RIMM module is, but in general electronics we use metal plates to disperse heat. Removing plate will result in either a fire or fried electronics. If it looks more like it has encapsulated something it may be there as a shield (ie stopping radio waves from entering or exiting module) as this may cause interference resulting in erroneous behavior.
Specific heat capacity
The main purpose of a heat sink is to dissipate excessive heat away from the device that it is attached to. Some small integrated circuit components are so physically small that an over excess of heat generated by themselves would destroy the device. The heat sink is placed on the IC to prevent this from happening.
