Computer Fan; Heat Sink - Dell Inspiron 13z Manual

Processors are specifically designed for mobile devices, laptop
computers, desktop computers, servers, and so on. A processor designed
for mobile devices consumes less power compared to the ones designed
for desktop computers or servers.

Computer Fan

A computer fan cools the internal components of a computer by
expelling hot air from the computer. Computer fans are commonly
used to cool components that have high power consumption and thus
generate a high amount of heat. Keeping the components cool helps in
protecting them from overheating, malfunctioning, and damage.
Fans are used to cool:
• Computer chassis
• Processor
• Graphics card
• Chipset
• Hard drive and so on.

Heat Sink

Heat sinks are used to dissipate heat generated by the processor or some
high-end graphics cards. Heat sinks generally have a fan mounted above
them to increase airflow and are made up of fins or blades instead of a
single block of metal. This helps increase the surface area for maximum
heat dissipation. A layer of thermal grease is applied between the
processor/graphics card and the heat sink for easy exchange of heat.
