Other components are also susceptible to heat damage and are sometimes equipped with fans. Video adapter cards also produce a lot
of heat. Fans are dedicated to cool the graphics-processing unit (GPU).
Computers with extremely fast CPUs and GPUs might use a water-cooling system. A metal plate is placed over the processor, and water
is pumped over the top to collect the heat that the processor generates. The water is pumped to a radiator to release the heat into the
air and is then recirculated.
