Heatsinks are usually made of highly conductive metals which allow for heat rapid heat transfer (usually copper, aluminium or sometimes silver).
The mechanism in which this operates is the same in which electricity is allowed to pass through metal, via the electron swarm distribution and the ability of the electrons to move independently of the nucleus position. (see metallic bonding)
As with heat sinks, the heat is drawn away from the center and up the "fins" or "tails" because of the change in temperatures between the air around the fins and the temperature of the core. The fins and tails provide a greater surface area for the heat transfer to take place making it more efficient than a standard air cooling approach.
add. One specialized application of heatsinks is inside computer chips, where several watts need to be dispersed. Diamond and Moissanite are used here as these materials have the highest thermal conductivities, apart from graphene.

Does heat loss happen more vigorously through conduction than radiation?
Depends on the material itself(for conduction) or it's surface and the temperature(for radiation) - at very high temperatures(like a lightbulb filament), radiation is far more significant then conduction, but a heatsink in a normal PC is doing to be far more dependant on conduction then radiation...
Write the condition required for conduction of heat?
It require the medium with conduction property. The medium must be stable enough to withstand heat and not thermally decompose. It is then apply temperature difference to start such conduction heat transfer.
What can be used to fly A radiation B convection C conduction?
convection
What units are used to express a heat transfer?
conduction, convention, and radiation
Which process conduction convection or radiation is used to remove heat from car raditor?
Its actually conduction - to the air passing through (due to the fan ... or the forward velocity of the car).

Is a thermal conduction a physical property?
Thermal conductivity is a Physical property
What did older CPUs use instead of a cooling fan?
Some used a simple passive heatsink, or used parts of the computer's case itself to dissipate heat. Other required no heatsink at all.
What the heatsink does?
It draws heat away fom the object that is is being used on.
Which matarial is used for light conduction?
Fiberglass is used for light conduction.
How do you remove heatsink acer 4730z?
Depends on what they used if you remove the CPU heatsink you mite have to remove the CPU with it. If the heatcontact was a glue type then u cant without removeing the proccesor
What can travel through shiny convention or conduction?
A shiny surface will reflect light and heat, and thus is not a conductor. This property is used in a vacuum flask. If a shiny surface is in intimate contact with a hot object, then thermal conduction will take place.
Why do you need a Thermal compound for a heatsink?
Thermal compound rests between the CPU (heatspreader) and the heatsink, and is used to improve heat conductivity in areas where the two metal surfaces aren't completely flush.
Is silica gel a good heat thermal conductor?
No, silica gel is a gritty sand like material used to absorb water and thus keep humidity down in sensitive devices.Perhaps (considering your misspelling) you were thinking of silicone grease. Yes, silicone grease is a white colored sticky synthetic grease with good thermal conduction properties that is applied between a high wattage component and a heatsink. It is not as good a thermal conductor as metal, but is used primarily to prevent voids between the component and the heatsink which would cause hotspots.If a truly good thermal conductor is needed between a component and the heatsink, silver filled epoxy would be the best material.
What property of matter does a hot spoon that was left in boiling soup illustrate?
CONDUCTION
How can conduction be helpful?
Conduction can cause a spark which can light a light bulb. Conduction can be used to heat up metals.
Write the condition required for conduction of heat?
It require the medium with conduction property. The medium must be stable enough to withstand heat and not thermally decompose. It is then apply temperature difference to start such conduction heat transfer.
