The combination heat sink and cooling fan is sometimes called a cooler.
With a heat sink and fan.
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 )
your moma is my heat sink
A central processing unit (CPU), is under the fan and heat sink. The processor creates a lot of heat as it works, and would soon burn-out if not cooled.
The difference is that Passive cooling is just a heat sink that dissipates the heat into the air without the help of a fan. Active cooling is when you have a heat sink and a fan is directly blowing/sucking air thru the heat sink to cool it. The fan does not have to be on the heat sink as with some dell/gateway computers. The fan is on the plastic shroud, which in turn fits right over the heat sink. Water cooling and phase-change cooling is also considered active cooling.
A heatsink is a piece of metal that sits on top of your computers CPU (and also some other components) that helps conduct heat away from it, the fan you're referring to sits on top of the heat sink and moves the heat away and (ideally) out of the case.
Thermal grease to allow heat to transfer to the heat sink.
Cooling fan is always better. By:B.J
The heat sink absorbs the heat from the processor and then the fan disperses the heat.
Not sure what you mean. The fan is very small and spins to blow air across a heat sink that is attached to the processor. It isn't attached to anything but itself and the housing that screws to the motherboard or case.
